Correction to: Minimally conscious state “plus”: diagnostic criteria and relation to functional recovery (Journal of Neurology, (2020), 267, 5, (1245-1254), 10.1007/s00415-019-09628-y)
'Springer Science and Business Media LLC', 2020Co-Authors: Thibaut Aurore, Bodien Y. G., Laureys Steven, Giacino J. T.Abstract:audience: researcher, professional, studentFollowing Electronic Publication of the above-referenced manuscript, we discovered that one of the three criteria we proposed to establish command-following in the MCS+ syndrome was inadvertently omitted in some parts of the manuscript. Specifically, "object recognition" was omitted from the criteria used to diagnose MCS+. We operationally define command-following as a Coma Recovery Scale-Revised (CRS-R) Auditory Subscale score of 3 (i.e. reproducible command-following: A3) or 4 (i.e. consistent commandfollowing: A4), or a Visual Subscale score of 5 (i.e. object recognition: V5). However, in Tables 1 and 2 and Figs. 2 and 3, we failed to include object recognition as a criterion for MCS+. In addition, in Fig. 4 (CRS-R Face Sheet), object recognition is not labeled as a criterion for MCS+. Therefore, we would like to highlight the corrected parts of our manuscript to clarify that the criteria for "command-following" include object recognition (V5) as well as reproducible (A3) and consistent (A4) command-following. Please note that these modifications do not change any of the findings of the study. Please find the individual corrections here: In the section “Methods” the paragraph “consistent command following” needs to be replaced by: Command following: At least three clearly-discernible behavioral responses are observed over four consecutive trials on at least one of two commands. Note that this definition also includes object recognition. At the end of the “Procedures” paragraph, the following text needs to be added before Table 1. Note that we did not include “attention” from the Arousal Subscale as a criterion for MCS+ because all responses, regardless of accuracy, are considered when scoring this item. This item can be scored even in the absence of intact language function. For example, a patient with aphasia who does not comprehend language but understands that a response is anticipated may meet the required criteria. At the end of the section “Results” the word “lower” needs to be replaced by “higher”: The MCS- group had significantly higher (i.e., worse) DRS scores than all other groups (all p values < 0.05—supplementary Fig. S3).

Henneguya Pseudoplatystoma N. Sp. Causing Reduction In Epithelial Area Of Gills In The Farmed Pintado, A South American Catfish: Histopathology And Ultrastructure
2015Co-Authors: Naldoni J., Arana S., Maia A.a.m., Ceccarelli P.s., Tavares L.e.r., Borges F.a., Pozo C.f., Adriano E.a.Abstract:The present study is part of an ongoing investigation into the characteristics of Myxozoan parasites of Brazilian freshwater fish and was carried out using morphology, histopathology and electron microscopy analysis. A new Myxosporea species (Henneguya pseudoplatystoma) is described causing an important reduction in gill function in the farmed pintado (a hybrid fish from a cross between Pseudoplatystoma corruscans and Pseudoplatystoma fasciatum), which is a commercially important South American catfish. From a total of 98 pintado juveniles from fish farms in the states of São Paulo and Mato Grosso do Sul (Brazil), 36 samples (36.7%) exhibited infection of the gill filaments. Infection was intense, with several plasmodia occurring on a same gill filament. The plasmodia were white and measured up to 0.5 mm in length; mature spores were ellipsoidal in the frontal view, measuring 33.2 ± 1.9 μm in total length, 10.4 ± 0.6 μm in body length, 3.4 ± 0.4 μm in width and 22.7 ± 1.7 μm in the caudal process. The polar capsules were elongated, measuring 3.3 ± 0.4 μm in length and 1.0 ± 0.1 μm in width and the polar filaments had six to seven turns. Histopathological analysis revealed the parasite in the connective tissue of the gill filaments and lamella. No inflammatory process was observed, but the development of the plasmodia reduced the area of functional epithelium. Ultrastructural analyses revealed a single plasmodial wall, which was in direct contact with the host cells and had numerous projections in direction of the host cells as well as extensive pinocytotic canals. A thick layer (2-6 μm) of fibrous material and numerous mitochondria were found in the ectoplasm. Generative cells and the earliest stage of sporogenesis were seen more internally. Advanced spore developmental stages and mature spores were found in the central portion of the plasmodia. © 2009 Elsevier B.V.

Myxobolus Cordeiroi N. Sp., A Parasite Of Zungaro Jahu (siluriformes: Pimelodiade) From Brazilian Pantanal: Morphology, Phylogeny And Histopathology
2015Co-Authors: Adriano E.a., Arana S., Ceccarelli P.s., Alves A.l., Silva M.r.m., Henrique-silva F., Maia A.a.m.Abstract:This work is part of an ongoing investigation into the characteristics of Myxozoan parasites of freshwater fish in Brazil and was carried out using morphology, histopathology and molecular analysis. A new Myxosporea species (Myxobolus cordeiroi) is described infecting the jaú catfish (Zungaro jahu). Fifty jaú specimens were examined and 78% exhibited plasmodia of the parasite. The plasmodia were white and round, measuring 0.3-2.0 mm in diameter and the development occurred in the gill arch, skin, serosa of the body cavity, urinary bladder and eye. The spores had an oval body and the spore wall was smooth. Partial sequencing of the 18S rDNA gene resulted in a total of 505 bp and the alignment of the sequences obtained from samples in different organs revealed 100% identity. In the phylogenetic analysis, the Myxobolus species clustered into two clades-one primarily parasites of freshwater fish and the other primarily parasites of marine fish. M. cordeiroi n. sp. was clustered in a basal position in the freshwater fish species clade. The histological analysis revealed the parasite in the connective tissue of the different infected sites, thereby exhibiting affinity to this tissue. The plasmodium was surrounded by an outer collagen capsule of fibers with distinct orientation from the adjacent connective tissue and an inner layer composed of delicate collagen fibrils-more precisely reticular fibers. The development of the parasite in the cornea and urinary bladder caused considerable stretching of the epithelium. © 2009 Elsevier B.V.

Phylogenetic And Host-parasite Relationship Analysis Of Henneguya Multiplasmodialis N. Sp. Infecting Pseudoplatystoma Spp. In Brazilian Pantanal Wetland
2015Co-Authors: Adriano E.a., Naldoni J., Maia A.a.m., Ceccarelli P.s., Silva M.r.m., Carriero M.m., Arana S.Abstract:A new species of the genus Henneguya (Henneguya multiplasmodialis n. sp.) was found infecting the gills of three of 89 specimens (3.3%) of Pseudoplatystoma corruscans and two of 79 specimens (2.6%) of Pseudoplatystoma reticulatum from rivers in the Pantanal wetland, Brazil. Partial sequencing of the 18S rDNA gene of the spores obtained from one plasmodium from the gills of P. corruscans and other one from the gills of P. reticulatum, respectively, resulted in a total of 1560 and 1147 base pairs. As the spores of H. multiplasmodialis n. sp. resemble those of Henneguya corruscans, which is also a parasite of P. corruscans, sequencing of the 18S rDNA gene of the spores of H. corruscans found on P. corruscans caught in the Brazilian Pantanal wetland was also provided to avoid any taxonomic pendency between these two species, resulting in 1913 base pairs. The sequences of H. multiplasmodialis n. sp. parasite of P. corruscans and P. reticulatum and H. corruscans did not match any of the Myxozoa available in the GenBank. The similarity of H. multiplasmodialis n. sp. obtained from P. corruscans to that from P. reticulatum was of 99.7%. Phylogeny revealed a strong tendency among Henneguya species to form clades based on the order and/or family of the host fish. H. multiplasmodialis n. sp. clustered in a clade with Henneguya eirasi and H. corruscans, which are also parasites of siluriforms of the family Pimelodidae and, together with the clade composed of Henneguya spp. parasites of siluriforms of the family Ictaluridae, formed a monophyletic clade of parasites of siluriform hosts. The histological study revealed that the wall of the plasmodia of H. multiplasmodialis n. sp. were covered with a stratified epithelium rich in club cells and supported by a layer of connective tissue. The interior of the plasmodia had a network of septa that divided the plasmodia into numerous compartments. The septa were composed of connective tissue also covered on both sides with a stratified epithelium rich in club cells. Inflammatory infiltrate was found in the tissue surrounding the plasmodia as well as in the septa. © 2011 Elsevier B.V.1852-4110120Adriano, E.A., Arana, S., Ceccarelli, P.C., Cordeiro, N.S., Light and scanning electron microscopy of Myxobolus porofilus n. sp.

Myxidium Ceccarellii N. Sp. (myxosporea) From The Gallbladder Of Leporinus Elongatus (anastomidae) From The São Francisco River, Brazil
Springer Verlag, 2015Co-Authors: Adriano E.a., Silva M.r.m., Atkinson S.d., Bartholomew J.l., Maia A.a.m.Abstract:During a survey of myxozoan parasites of freshwater fish from the São Francisco River in Minas Gerais State, Brazil, plasmodia of Myxidium ceccarellii n. sp. were found in gallbladders of two out of six specimens (22 %) of Leporinus elongatus (Anastomidae). Parasite plasmodia were translucent and greenish, with disporic sporoblasts that develop asynchronously. Mature myxospores were ellipsoidal in frontal and lateral views, with slightly pointed ends. The surfaces of each valve had four to six longitudinal grooves. Spores dimensions were as follows: length 17.7±0.5 μm (17.1-18.1), width 10.4±0.47 μm (9.8-11.3), and thickness 10.1±0.27 μm (9.6-10.4). Two polar capsules, one at either end of the spore, had the length of 6.3±0.5 μm (5.7-7.0) and width of 6.4±0.44 μm (5.7-6.9), with four to five polar filament turns. Some aberrant spores had one or three polar capsules. Partial sequencing of M. ceccarellii n. sp. small subunit ribosomal RNA (ssrRNA) gene resulted in 1,845 bp. This is the first molecular study of a Myxidium species that parasitizes a South American freshwater fish. Phylogenetic reconstruction using ssrRNA gene sequences showed that M. ceccarellii n. sp. was positioned basally in a recognized clade of myxozoans that infect the biliary systems of nonfish vertebrates. © 2014 Springer-Verlag.113726652670Altschul, S.F., Madden, T.L., Schaffer, A.A., Zhang, J., Zhang, Z., Miller, W., Lipman, D.J., Gapped BLAST and PSI-BLAST: A new generation of protein database search programs (1997) Nucleic Acids Research, 25 (17), pp. 3389-3402. , DOI 10.1093/nar/25.17.3389(2012) Região Hidrográfica Amazônica: A Maior Do Mundo Em Disponibilidade de Água, , http://www2.ana.gov.br/Paginas/portais/bacias/amazonica.aspx, Accessed on 19 Mar 2012Azevedo, C., Casal, G., Clemente, S.C., Lopes, L.M.S., Matos, P., Abdel-Baki, A.A., Oliveira, E., Matos, E., Myxidium volitans sp.

The Morphological And Molecular Characterization Of Henneguya Rotunda N. Sp., A Parasite Of The Gill Arch And Fins Of Salminus Brasiliensis From The Mogi Guaçu River, Brazil
'Springer Science and Business Media LLC', 2015Co-Authors: Moreira G.s.a., Adriano E.a., Ceccarelli P.s., Silva M.r.m., Maia A.a.m.Abstract:A new species of myxosporea (Henneguya rotunda n. sp.) was found in the membrane of the gill arch and the fins of Salminus brasiliensis in the Mogi Guaçu River, municipality of Pirassununga, São Paulo state, Brazil. Morphological and morphometric analyses using light microscopy revealed parasites with similar characteristics at both infection sites. The mature spores found infecting the fins had oval spore body with 7.1±0.2 μm in length, 5.6±0.2 μm in width, 3.7±0.1 μm in thickness, 16.4±1.2 μm in length of the caudal process, and 23.6±1.1 μm in total length of the spore. In a frontal view, the polar capsule was observed to be symmetrical with 3.4±0.2 μm in length and 1.8±0.1 μm in width. Mature spores contain six to seven turns of the polar filaments. The morphometric data concerning the spores obtained from plasmodia from the membrane of the gill arch were similar to those from the fins. Ultrastructure analysis revealed that the plasmodial wall was formed by a single membrane and had numerous pinocytotic canals connecting the outside of the plasmodia to the ectoplasm zone. Beyond that, various electron-translucent vesicles also were observed at the periphery of the plasmodium. The molecular analyses of the 18S rDNA gene from the spores obtained from the gill arch membrane and fin membrane showed that these sequences shared 100 % similarity. Phylogenetic studies using maximum parsimony and maximum likelihood methods demonstrated the polyphyletic clustering of the myxosporean parasites of characiform fishes.

Henneguya Pseudoplatystoma N. Sp. Causing Reduction In Epithelial Area Of Gills In The Farmed Pintado, A South American Catfish: Histopathology And Ultrastructure
2015Co-Authors: Naldoni J., Arana S., Maia A.a.m., Ceccarelli P.s., Tavares L.e.r., Borges F.a., Pozo C.f., Adriano E.a.Abstract:The present study is part of an ongoing investigation into the characteristics of Myxozoan parasites of Brazilian freshwater fish and was carried out using morphology, histopathology and electron microscopy analysis. A new Myxosporea species (Henneguya pseudoplatystoma) is described causing an important reduction in gill function in the farmed pintado (a hybrid fish from a cross between Pseudoplatystoma corruscans and Pseudoplatystoma fasciatum), which is a commercially important South American catfish. From a total of 98 pintado juveniles from fish farms in the states of São Paulo and Mato Grosso do Sul (Brazil), 36 samples (36.7%) exhibited infection of the gill filaments. Infection was intense, with several plasmodia occurring on a same gill filament. The plasmodia were white and measured up to 0.5 mm in length; mature spores were ellipsoidal in the frontal view, measuring 33.2 ± 1.9 μm in total length, 10.4 ± 0.6 μm in body length, 3.4 ± 0.4 μm in width and 22.7 ± 1.7 μm in the caudal process. The polar capsules were elongated, measuring 3.3 ± 0.4 μm in length and 1.0 ± 0.1 μm in width and the polar filaments had six to seven turns. Histopathological analysis revealed the parasite in the connective tissue of the gill filaments and lamella. No inflammatory process was observed, but the development of the plasmodia reduced the area of functional epithelium. Ultrastructural analyses revealed a single plasmodial wall, which was in direct contact with the host cells and had numerous projections in direction of the host cells as well as extensive pinocytotic canals. A thick layer (2-6 μm) of fibrous material and numerous mitochondria were found in the ectoplasm. Generative cells and the earliest stage of sporogenesis were seen more internally. Advanced spore developmental stages and mature spores were found in the central portion of the plasmodia. © 2009 Elsevier B.V.

Myxobolus Cordeiroi N. Sp., A Parasite Of Zungaro Jahu (siluriformes: Pimelodiade) From Brazilian Pantanal: Morphology, Phylogeny And Histopathology
2015Co-Authors: Adriano E.a., Arana S., Ceccarelli P.s., Alves A.l., Silva M.r.m., Henrique-silva F., Maia A.a.m.Abstract:This work is part of an ongoing investigation into the characteristics of Myxozoan parasites of freshwater fish in Brazil and was carried out using morphology, histopathology and molecular analysis. A new Myxosporea species (Myxobolus cordeiroi) is described infecting the jaú catfish (Zungaro jahu). Fifty jaú specimens were examined and 78% exhibited plasmodia of the parasite. The plasmodia were white and round, measuring 0.3-2.0 mm in diameter and the development occurred in the gill arch, skin, serosa of the body cavity, urinary bladder and eye. The spores had an oval body and the spore wall was smooth. Partial sequencing of the 18S rDNA gene resulted in a total of 505 bp and the alignment of the sequences obtained from samples in different organs revealed 100% identity. In the phylogenetic analysis, the Myxobolus species clustered into two clades-one primarily parasites of freshwater fish and the other primarily parasites of marine fish. M. cordeiroi n. sp. was clustered in a basal position in the freshwater fish species clade. The histological analysis revealed the parasite in the connective tissue of the different infected sites, thereby exhibiting affinity to this tissue. The plasmodium was surrounded by an outer collagen capsule of fibers with distinct orientation from the adjacent connective tissue and an inner layer composed of delicate collagen fibrils-more precisely reticular fibers. The development of the parasite in the cornea and urinary bladder caused considerable stretching of the epithelium. © 2009 Elsevier B.V.

Phylogenetic And Host-parasite Relationship Analysis Of Henneguya Multiplasmodialis N. Sp. Infecting Pseudoplatystoma Spp. In Brazilian Pantanal Wetland
2015Co-Authors: Adriano E.a., Naldoni J., Maia A.a.m., Ceccarelli P.s., Silva M.r.m., Carriero M.m., Arana S.Abstract:A new species of the genus Henneguya (Henneguya multiplasmodialis n. sp.) was found infecting the gills of three of 89 specimens (3.3%) of Pseudoplatystoma corruscans and two of 79 specimens (2.6%) of Pseudoplatystoma reticulatum from rivers in the Pantanal wetland, Brazil. Partial sequencing of the 18S rDNA gene of the spores obtained from one plasmodium from the gills of P. corruscans and other one from the gills of P. reticulatum, respectively, resulted in a total of 1560 and 1147 base pairs. As the spores of H. multiplasmodialis n. sp. resemble those of Henneguya corruscans, which is also a parasite of P. corruscans, sequencing of the 18S rDNA gene of the spores of H. corruscans found on P. corruscans caught in the Brazilian Pantanal wetland was also provided to avoid any taxonomic pendency between these two species, resulting in 1913 base pairs. The sequences of H. multiplasmodialis n. sp. parasite of P. corruscans and P. reticulatum and H. corruscans did not match any of the Myxozoa available in the GenBank. The similarity of H. multiplasmodialis n. sp. obtained from P. corruscans to that from P. reticulatum was of 99.7%. Phylogeny revealed a strong tendency among Henneguya species to form clades based on the order and/or family of the host fish. H. multiplasmodialis n. sp. clustered in a clade with Henneguya eirasi and H. corruscans, which are also parasites of siluriforms of the family Pimelodidae and, together with the clade composed of Henneguya spp. parasites of siluriforms of the family Ictaluridae, formed a monophyletic clade of parasites of siluriform hosts. The histological study revealed that the wall of the plasmodia of H. multiplasmodialis n. sp. were covered with a stratified epithelium rich in club cells and supported by a layer of connective tissue. The interior of the plasmodia had a network of septa that divided the plasmodia into numerous compartments. The septa were composed of connective tissue also covered on both sides with a stratified epithelium rich in club cells. Inflammatory infiltrate was found in the tissue surrounding the plasmodia as well as in the septa. © 2011 Elsevier B.V.1852-4110120Adriano, E.A., Arana, S., Ceccarelli, P.C., Cordeiro, N.S., Light and scanning electron microscopy of Myxobolus porofilus n. sp.

Morphology And Host-parasite Interaction Of Henneguya Azevedoi N. Sp., Parasite Of Gills Of Leporinus Obtusidens From Mogi-guaçu River, Brazil
2015Co-Authors: Barassa B., Arana S., Adriano E.a., Cordeiro N.s., Ceccarelli P.s.Abstract:Henneguya azevedoi n. sp. is described from the piava (Leporinus obtusidens). Between 2005 and 2007, 60 fish were collected from the Mogi-Guaçu River near Cachoeira de Emas Falls located in the municipality of Pirassununga, state of São Paulo, Brazil. A total of 70% had plasmodia of the parasite. The plasmodia were white, spherical, and measured 40-200 μm in diameter. Histopathological analysis revealed that the development of the parasite was intralamellar and caused stretching of the epithelium, with accentuated deformation, as well as compression of the capillary and adjacent tissues. Ultrastructural analysis revealed that the wall of the plasmodium was a single membrane in direct contact with the host cells and contained pinocytic canals that extended into the plasmodium. The development of the parasite was asynchronous, with the earliest stages at the periphery and mature spores in the central region. Mature spores were elongated in the frontal view [mean±standard deviation (range)]: 45.2±0.6 (45.0-47.0)μm in total length, 10.0± 0.07 (9.9-10.2)μm in body length, 35.6±0.9 (34.9- 36.5)μm in caudal process length, and 4.4±0.4 (4.0- 5.0)μm in body width. The polar capsules were elongated and equal in size: 3.8±0.3 (3.5-4.0)μm in length and 1.0 μm in width. The polar filaments were coiled in six to seven turns and perpendicular to the axis of the capsule. Scanning electron microscopy revealed smooth valves and a conspicuous rim around the spore body. This is the first time that a myxosporean has been reported in L. obtusidens. © Springer-Verlag 2011.1102887894Abdel-Ghaffar, F., Abdel-Baki, A.S., Bayoumy, E.M., Bashtar, A.R., Qurieshy, S.A., Morsey, K.S., Alghamdy, A., Mehlhorn, H., Light and electron microscopic study on Henneguya suprabranchiae Landsberg, 1987 (Myxozoa: Myxosporea) infecting Oreochromis niloticus, a new host record (2008) Parasitol Res, 103, pp. 609-617Adriano, E.A., Arana, S., Cordeiro, N.S., Histology, ultrastructure and prevalence of Henneguya piaractus (Myxosporea) infecting the gills of Piaractus mesopotamicus (Characidae) cultivated in Brazil (2005) Diseases of Aquatic Organisms, 64 (3), pp. 229-235Adriano, E.A., Arana, S., Cordeiro, N.S., Histophatology and ultrastructure of Henneguya caudalongula sp. n. infecting Prochilodus lineatus (Pisces: Prochilodontidae) cultivated in the state of São Paulo, Brazil (2005) Memorias do Instituto Oswaldo Cruz, 100 (2), pp. 177-181Ali, M.A., Abdel-Baki, A.S., Sakran, Th., Entzeroth, R., Abdel-Ghaffar, F., Myxobolus lubati n. sp.

Myxidium Ceccarellii N. Sp. (myxosporea) From The Gallbladder Of Leporinus Elongatus (anastomidae) From The São Francisco River, Brazil
Springer Verlag, 2015Co-Authors: Adriano E.a., Silva M.r.m., Atkinson S.d., Bartholomew J.l., Maia A.a.m.Abstract:During a survey of myxozoan parasites of freshwater fish from the São Francisco River in Minas Gerais State, Brazil, plasmodia of Myxidium ceccarellii n. sp. were found in gallbladders of two out of six specimens (22 %) of Leporinus elongatus (Anastomidae). Parasite plasmodia were translucent and greenish, with disporic sporoblasts that develop asynchronously. Mature myxospores were ellipsoidal in frontal and lateral views, with slightly pointed ends. The surfaces of each valve had four to six longitudinal grooves. Spores dimensions were as follows: length 17.7±0.5 μm (17.1-18.1), width 10.4±0.47 μm (9.8-11.3), and thickness 10.1±0.27 μm (9.6-10.4). Two polar capsules, one at either end of the spore, had the length of 6.3±0.5 μm (5.7-7.0) and width of 6.4±0.44 μm (5.7-6.9), with four to five polar filament turns. Some aberrant spores had one or three polar capsules. Partial sequencing of M. ceccarellii n. sp. small subunit ribosomal RNA (ssrRNA) gene resulted in 1,845 bp. This is the first molecular study of a Myxidium species that parasitizes a South American freshwater fish. Phylogenetic reconstruction using ssrRNA gene sequences showed that M. ceccarellii n. sp. was positioned basally in a recognized clade of myxozoans that infect the biliary systems of nonfish vertebrates. © 2014 Springer-Verlag.113726652670Altschul, S.F., Madden, T.L., Schaffer, A.A., Zhang, J., Zhang, Z., Miller, W., Lipman, D.J., Gapped BLAST and PSI-BLAST: A new generation of protein database search programs (1997) Nucleic Acids Research, 25 (17), pp. 3389-3402. , DOI 10.1093/nar/25.17.3389(2012) Região Hidrográfica Amazônica: A Maior Do Mundo Em Disponibilidade de Água, , http://www2.ana.gov.br/Paginas/portais/bacias/amazonica.aspx, Accessed on 19 Mar 2012Azevedo, C., Casal, G., Clemente, S.C., Lopes, L.M.S., Matos, P., Abdel-Baki, A.A., Oliveira, E., Matos, E., Myxidium volitans sp.

T.Abstract:audience: researcher, professional, studentFollowing Electronic Publication of the above-referenced manuscript, we discovered that one of the three criteria we proposed to establish command-following in the MCS+ syndrome was inadvertently omitted in some parts of the manuscript. Specifically, "object recognition" was omitted from the criteria used to diagnose MCS+. We operationally define command-following as a Coma Recovery Scale-Revised (CRS-R) Auditory Subscale score of 3 (i.e. reproducible command-following: A3) or 4 (i.e. consistent commandfollowing: A4), or a Visual Subscale score of 5 (i.e. object recognition: V5).

In addition, in Fig. 4 (CRS-R Face Sheet), object recognition is not labeled as a criterion for MCS+. Therefore, we would like to highlight the corrected parts of our manuscript to clarify that the criteria for "command-following" include object recognition (V5) as well as reproducible (A3) and consistent (A4) command-following.

Note that this definition also includes object recognition. At the end of the “Procedures” paragraph, the following text needs to be added before Table 1. Note that we did not include “attention” from the Arousal Subscale as a criterion for MCS+ because all responses, regardless of accuracy, are considered when scoring this item.

Henneguya Pseudoplatystoma N. Sp. Causing Reduction In Epithelial Area Of Gills In The Farmed Pintado, A South American Catfish: Histopathology And Ultrastructure
2015Co-Authors: Naldoni J., Arana S., Maia A.a.m., Ceccarelli P.s., Tavares L.e.r., Borges F.a., Pozo C.f., Adriano E.a.Abstract:The present study is part of an ongoing investigation into the characteristics of Myxozoan parasites of Brazilian freshwater fish and was carried out using morphology, histopathology and electron microscopy analysis. A new Myxosporea species (Henneguya pseudoplatystoma) is described causing an important reduction in gill function in the farmed pintado (a hybrid fish from a cross between Pseudoplatystoma corruscans and Pseudoplatystoma fasciatum), which is a commercially important South American catfish. From a total of 98 pintado juveniles from fish farms in the states of São Paulo and Mato Grosso do Sul (Brazil), 36 samples (36.7%) exhibited infection of the gill filaments. Infection was intense, with several plasmodia occurring on a same gill filament. The plasmodia were white and measured up to 0.5 mm in length; mature spores were ellipsoidal in the frontal view, measuring 33.2 ± 1.9 μm in total length, 10.4 ± 0.6 μm in body length, 3.4 ± 0.4 μm in width and 22.7 ± 1.7 μm in the caudal process. The polar capsules were elongated, measuring 3.3 ± 0.4 μm in length and 1.0 ± 0.1 μm in width and the polar filaments had six to seven turns. Histopathological analysis revealed the parasite in the connective tissue of the gill filaments and lamella. No inflammatory process was observed, but the development of the plasmodia reduced the area of functional epithelium. Ultrastructural analyses revealed a single plasmodial wall, which was in direct contact with the host cells and had numerous projections in direction of the host cells as well as extensive pinocytotic canals. A thick layer (2-6 μm) of fibrous material and numerous mitochondria were found in the ectoplasm. Generative cells and the earliest stage of sporogenesis were seen more internally. Advanced spore developmental stages and mature spores were found in the central portion of the plasmodia. © 2009 Elsevier B.V.

Myxobolus Cordeiroi N. Sp., A Parasite Of Zungaro Jahu (siluriformes: Pimelodiade) From Brazilian Pantanal: Morphology, Phylogeny And Histopathology
2015Co-Authors: Adriano E.a., Arana S., Ceccarelli P.s., Alves A.l., Silva M.r.m., Henrique-silva F., Maia A.a.m.Abstract:This work is part of an ongoing investigation into the characteristics of Myxozoan parasites of freshwater fish in Brazil and was carried out using morphology, histopathology and molecular analysis. A new Myxosporea species (Myxobolus cordeiroi) is described infecting the jaú catfish (Zungaro jahu). Fifty jaú specimens were examined and 78% exhibited plasmodia of the parasite. The plasmodia were white and round, measuring 0.3-2.0 mm in diameter and the development occurred in the gill arch, skin, serosa of the body cavity, urinary bladder and eye. The spores had an oval body and the spore wall was smooth. Partial sequencing of the 18S rDNA gene resulted in a total of 505 bp and the alignment of the sequences obtained from samples in different organs revealed 100% identity. In the phylogenetic analysis, the Myxobolus species clustered into two clades-one primarily parasites of freshwater fish and the other primarily parasites of marine fish. M. cordeiroi n. sp. was clustered in a basal position in the freshwater fish species clade. The histological analysis revealed the parasite in the connective tissue of the different infected sites, thereby exhibiting affinity to this tissue. The plasmodium was surrounded by an outer collagen capsule of fibers with distinct orientation from the adjacent connective tissue and an inner layer composed of delicate collagen fibrils-more precisely reticular fibers. The development of the parasite in the cornea and urinary bladder caused considerable stretching of the epithelium. © 2009 Elsevier B.V.

Phylogenetic And Host-parasite Relationship Analysis Of Henneguya Multiplasmodialis N. Sp. Infecting Pseudoplatystoma Spp. In Brazilian Pantanal Wetland
2015Co-Authors: Adriano E.a., Naldoni J., Maia A.a.m., Ceccarelli P.s., Silva M.r.m., Carriero M.m., Arana S.Abstract:A new species of the genus Henneguya (Henneguya multiplasmodialis n. sp.) was found infecting the gills of three of 89 specimens (3.3%) of Pseudoplatystoma corruscans and two of 79 specimens (2.6%) of Pseudoplatystoma reticulatum from rivers in the Pantanal wetland, Brazil. Partial sequencing of the 18S rDNA gene of the spores obtained from one plasmodium from the gills of P. corruscans and other one from the gills of P. reticulatum, respectively, resulted in a total of 1560 and 1147 base pairs. As the spores of H. multiplasmodialis n. sp. resemble those of Henneguya corruscans, which is also a parasite of P. corruscans, sequencing of the 18S rDNA gene of the spores of H. corruscans found on P. corruscans caught in the Brazilian Pantanal wetland was also provided to avoid any taxonomic pendency between these two species, resulting in 1913 base pairs. The sequences of H. multiplasmodialis n. sp. parasite of P. corruscans and P. reticulatum and H. corruscans did not match any of the Myxozoa available in the GenBank. The similarity of H. multiplasmodialis n. sp. obtained from P. corruscans to that from P. reticulatum was of 99.7%. Phylogeny revealed a strong tendency among Henneguya species to form clades based on the order and/or family of the host fish. H. multiplasmodialis n. sp. clustered in a clade with Henneguya eirasi and H. corruscans, which are also parasites of siluriforms of the family Pimelodidae and, together with the clade composed of Henneguya spp. parasites of siluriforms of the family Ictaluridae, formed a monophyletic clade of parasites of siluriform hosts. The histological study revealed that the wall of the plasmodia of H. multiplasmodialis n. sp. were covered with a stratified epithelium rich in club cells and supported by a layer of connective tissue. The interior of the plasmodia had a network of septa that divided the plasmodia into numerous compartments. The septa were composed of connective tissue also covered on both sides with a stratified epithelium rich in club cells. Inflammatory infiltrate was found in the tissue surrounding the plasmodia as well as in the septa. © 2011 Elsevier B.V.1852-4110120Adriano, E.A., Arana, S., Ceccarelli, P.C., Cordeiro, N.S., Light and scanning electron microscopy of Myxobolus porofilus n. sp.

Morphology And Host-parasite Interaction Of Henneguya Azevedoi N. Sp., Parasite Of Gills Of Leporinus Obtusidens From Mogi-guaçu River, Brazil
2015Co-Authors: Barassa B., Arana S., Adriano E.a., Cordeiro N.s., Ceccarelli P.s.Abstract:Henneguya azevedoi n. sp. is described from the piava (Leporinus obtusidens). Between 2005 and 2007, 60 fish were collected from the Mogi-Guaçu River near Cachoeira de Emas Falls located in the municipality of Pirassununga, state of São Paulo, Brazil. A total of 70% had plasmodia of the parasite. The plasmodia were white, spherical, and measured 40-200 μm in diameter. Histopathological analysis revealed that the development of the parasite was intralamellar and caused stretching of the epithelium, with accentuated deformation, as well as compression of the capillary and adjacent tissues. Ultrastructural analysis revealed that the wall of the plasmodium was a single membrane in direct contact with the host cells and contained pinocytic canals that extended into the plasmodium. The development of the parasite was asynchronous, with the earliest stages at the periphery and mature spores in the central region. Mature spores were elongated in the frontal view [mean±standard deviation (range)]: 45.2±0.6 (45.0-47.0)μm in total length, 10.0± 0.07 (9.9-10.2)μm in body length, 35.6±0.9 (34.9- 36.5)μm in caudal process length, and 4.4±0.4 (4.0- 5.0)μm in body width. The polar capsules were elongated and equal in size: 3.8±0.3 (3.5-4.0)μm in length and 1.0 μm in width. The polar filaments were coiled in six to seven turns and perpendicular to the axis of the capsule. Scanning electron microscopy revealed smooth valves and a conspicuous rim around the spore body. This is the first time that a myxosporean has been reported in L. obtusidens. © Springer-Verlag 2011.1102887894Abdel-Ghaffar, F., Abdel-Baki, A.S., Bayoumy, E.M., Bashtar, A.R., Qurieshy, S.A., Morsey, K.S., Alghamdy, A., Mehlhorn, H., Light and electron microscopic study on Henneguya suprabranchiae Landsberg, 1987 (Myxozoa: Myxosporea) infecting Oreochromis niloticus, a new host record (2008) Parasitol Res, 103, pp. 609-617Adriano, E.A., Arana, S., Cordeiro, N.S., Histology, ultrastructure and prevalence of Henneguya piaractus (Myxosporea) infecting the gills of Piaractus mesopotamicus (Characidae) cultivated in Brazil (2005) Diseases of Aquatic Organisms, 64 (3), pp. 229-235Adriano, E.A., Arana, S., Cordeiro, N.S., Histophatology and ultrastructure of Henneguya caudalongula sp. n. infecting Prochilodus lineatus (Pisces: Prochilodontidae) cultivated in the state of São Paulo, Brazil (2005) Memorias do Instituto Oswaldo Cruz, 100 (2), pp. 177-181Ali, M.A., Abdel-Baki, A.S., Sakran, Th., Entzeroth, R., Abdel-Ghaffar, F., Myxobolus lubati n. sp.

The Morphological And Molecular Characterization Of Henneguya Rotunda N. Sp., A Parasite Of The Gill Arch And Fins Of Salminus Brasiliensis From The Mogi Guaçu River, Brazil
'Springer Science and Business Media LLC', 2015Co-Authors: Moreira G.s.a., Adriano E.a., Ceccarelli P.s., Silva M.r.m., Maia A.a.m.Abstract:A new species of myxosporea (Henneguya rotunda n. sp.) was found in the membrane of the gill arch and the fins of Salminus brasiliensis in the Mogi Guaçu River, municipality of Pirassununga, São Paulo state, Brazil. Morphological and morphometric analyses using light microscopy revealed parasites with similar characteristics at both infection sites. The mature spores found infecting the fins had oval spore body with 7.1±0.2 μm in length, 5.6±0.2 μm in width, 3.7±0.1 μm in thickness, 16.4±1.2 μm in length of the caudal process, and 23.6±1.1 μm in total length of the spore. In a frontal view, the polar capsule was observed to be symmetrical with 3.4±0.2 μm in length and 1.8±0.1 μm in width. Mature spores contain six to seven turns of the polar filaments. The morphometric data concerning the spores obtained from plasmodia from the membrane of the gill arch were similar to those from the fins. Ultrastructure analysis revealed that the plasmodial wall was formed by a single membrane and had numerous pinocytotic canals connecting the outside of the plasmodia to the ectoplasm zone. Beyond that, various electron-translucent vesicles also were observed at the periphery of the plasmodium. The molecular analyses of the 18S rDNA gene from the spores obtained from the gill arch membrane and fin membrane showed that these sequences shared 100 % similarity. Phylogenetic studies using maximum parsimony and maximum likelihood methods demonstrated the polyphyletic clustering of the myxosporean parasites of characiform fishes. H. rotunda n. sp. clustered as a sister species of Myxobolus pantanalis, also a parasite of S. brasiliensis. © 2014 Springer-Verlag.113517031711Abdel-Baki, A.S., Sakran, T., Fayed, H., Zayed, E., Ultrastructural characteristics and histological impacts of Myxobolus naffari (Myxozoa: Myxosporea) infecting Nile labeo Labeo niloticus (Osteichthyes: Cichlidae) (2010) Dis Aquat Org, 90, pp. 207-213Abdel-Ghaffar, F., Abdel-Baki, A.A., Bayoumy, E.M., Bashtar, A.R., Al Qurieshy, S., Morsey, K.S., Alghamdy, A., Mehlhorn, H., Light and electron microscopic study on Henneguya suprabranchiae Landsberg, 1987 (Myxozoa: Myxosporea) infecting Oreochromis niloticus, a new host record (2008) Parasitol Res, 103 (3), pp. 609-617Adriano, E.A., Arana, S., Cordeiro, N.S., An ultrastructural and histopathological study of Henneguya pellucida n. sp.
