a new species of Syphacia seuratoxyuris nematoda oxyuridae from sooretamys angouya fischer 1814 rodentia cricetidae in argentina
Acta Tropica, 2014Co-Authors: Maria Del Rosario Robles, Guillermo Panisse, Graciela Teresa NavoneAbstract:Syphacia (Seuratoxyuris) hugoti n. sp. (Nematoda: Oxyuridae) is described from the cecum of Sooretamys angouya (Cricetidae: Sigmodontinae: Oryzomyini) captured in Formosa Province, Argentina. The diagnosis of the subgenus is emended, and the new species is separated from eight congeners by the distribution of submedian papillae and amphids, shape of the cephalic plate, presence of deirids, absence of cervical and lateral alae, length of the spicule, structure of the accessory hook of the gubernaculum and distance of excretory pore and vulva from the anterior extremity. The analysis suggests that S. (Se.) oryzomyos should be removed from Seuratoxyuris and redesignated as S. (Syphacia) oryzomyos n. comb. To date, of the species of Syphacia found in South and North American, 7 parasitize Oryzomyini rodents, of which two are distributed in Argentina. The present study constitutes the first record of the subgenus Seuratoxyuris from Argentina and the third record of a Syphacia species from rodents of the tribe Oryzomyini.

redescription of Syphacia venteli travassos 1937 nematoda oxyuridae from nectomys squamipes in argentina and brazil and description of a new species of Syphacia from melanomys caliginosus in colombia
Parasitology Research, 2010Co-Authors: Maria Del Rosario Robles, Graciela Teresa NavoneAbstract:Syphacia venteli Travassos, Mem Inst Oswaldo Cruz 32:607-613, 1937 is redescribed on the basis of specimens recovered from the type host, Nectomys squamipes (Brants 1827), from Brazil and Argentina. Specimens determined by Quentin (Bull Mus Natl Hist Nat 2:909-925, 1969) as S. venteli from Melanomys caliginosus (Tomes 1860) in Colombia were re-studied and assigned to a new species. In both species, structures such as the shape of the cephalic plate, details and distribution of the submedian papillae and amphids, presence and absence of the lateral and cervical alae, and shape and structure of the accessory hook of the gubernaculum were studied with the light microscope and scanning electron microscope. The present survey is the first detailed study of the species S. venteli since the original description, and the first record of this species from Argentina. Moreover, the present study suggests that the validity of some host species of Syphacia should be questioned and that through of the study of deposited specimens, a more exact number of parasitized host species can be confirmed, contributing to a better understanding of host specificity in this genus.

new morphological details and first records of heterakis spumosa and Syphacia muris from argentina
Comparative Parasitology, 2008Co-Authors: Maria Del Rosario Robles, Graciela Teresa Navone, Isabel Gomez E VillafaneAbstract:Heterakis spumosa and Syphacia muris are among the most common species parasitizing mammals. Although these nematodes have been reported from many hosts on several continents, in South America, they have only been recovered from the cecum of Rattus norvegicus from Brazil and Peru. This study provides morphological details of H. spumosa and S. muris. Moreover, this is the first record of these species in Argentina. Heterakis spumosa and S. muris were collected from specimens of R. norvegicus from Partido de Exaltacion de la Cruz, Buenos Aires Province, Argentina. This note presents relevant features observed with scanning electron microscopy (SEM) for H. spumosa, such as the presence of 4 papillae on the lips, the lateral alae forming a cuticular fold inside a groove that extends to the posterior end, double papillae on the tip of tail of the male, vulva with 5 cuticular processes, and 2 pair of sessile papillae on the female tail. Syphacia muris has a porous badge posterior to the amphids, and the excretory pore is located in an oval depression.

a new species of Syphacia nematoda oxyuridae from oligoryzomys nigripes rodentia cricetidae in argentina
Parasitology Research, 2007Co-Authors: Maria Del Rosario Robles, Graciela Teresa NavoneAbstract:The aim of this paper is to describe Syphacia kinsellai n. sp. (Nematoda: Oxyuridae) from the cecum of Oligoryzomys nigripes (Olfers 1818) (Sigmodontinae: Oryzomyini) captured in Misiones Province, Argentina. The new species can be differentiated from other species of the genus principally by the shape of the cephalic plate; distribution of submedian papillae and amphids; development of porous badge; presence of derids in females; absence of cervical and lateral alae; shape and structure of accessory hook of gubernaculum; and distance of excretory pore and vulva from the anterior extremity. Until the present, only two species of Syphacia had been reported from Argentina in sigmodontine rodents, the first one parasitizes an Oryzomyini host and the second one an Akodontini host. This new species is the second record of Syphacia from the tribe Oryzomyini in Argentina; however, we propose that the first record, S. oryzomae, should be treated as a nomen dubium.

A New Species of Syphacia (Nematoda: Oxyuridae) From Calomys laucha (Rodentia: Cricetidae) in an Agroecosystem of Central Argentina
The Journal of parasitology, 2011Co-Authors: Elba Juliana Rojas Herrera, Mariela Haydée Miño, Juliana Notarnicola, Maria Del Rosario RoblesAbstract:abstract: A new oxyurid nematode Syphacia hodarae n. sp. is described from the cecum and rectum of the cricetid rodent Calomys laucha Fischer, 1814 (Sigmodontinae, Phyllotini), captured in an agroecosystem of central Argentina. The new species is distinguished from other members of the genus mainly by the shape of the cephalic plate, presence of cervical alae in females, absence of lateral alae, and absence of deirids. Some characters are shared with Syphacia carlitosi, a parasite of Akodon azarae from the wetlands in Argentina. However, S. hodarae can be differentiated from this species by the absence of ornamentation on the accessory hook of the gubernaculum, length of spicule and gubernaculum, size of the eggs, and distance to the vulva from the anterior end. This is the first record of a Syphacia species from the tribe Phyllotini in Argentina, and the first time a Syphacia species is reported from C. laucha.

Parasite survey in mouse and rat colonies of Brazilian laboratory animal houses kept under differents sanitary barrier conditions
Arquivo Brasileiro De Medicina Veterinaria E Zootecnia, 2000Co-Authors: Rovilson Gilioli, Lenira Aparecida Guaraldo De Andrade, Luiz Augusto Corrêa Passos, F.a. Silva, Daniele Masselli Rodrigues, Ana Maria Aparecida GuaraldoAbstract:A parasitological study was undertaken to determine the health status of 15 mouse and 10 rat colonies bred in 18 Brazilian laboratory animal houses maintained under different sanitary barrier conditions which supply animals for teaching, research purposes and manufacture of biological products for medical or veterinary use. Parasitological methods were used for diagnosis of mites, lices, helminthes and protozoan parasites. A questionnaire was answered by institutions with the intention to obtain information about the existence of barriers against infections and of regular sanitary monitoring program of their colonies. The questionnaire data show that the majority of the animal houses investigated do not possess an efficient sanitary barrier system able to keep animals under controlled health sanitary conditions. Ecto and endoparasite infections are widespread in the colonies and multiple infections were common in animals from most facilities investigated. The prevalences of parasites detected among the mouse and rat colonies of the laboratory animal houses investigated were: Myocoptes musculinus (46.6%), Myobia musculi (26.6%), Radfordia ensifera (13.3%), Syphacia obvelata (86.6%), Aspiculuris tetraptera (60.0%), Hymenolepis nana (53.3%), Spironucleus muris (80.0%), Tritrichomonas muris (80.0%), Giardia muris (66.0%), Entamoeba muris (20.0%), Eimeria sp.

subsensitivity to beta adrenergic stimulation in atria from rats infested with Syphacia sp
Laboratory Animals, 2003Co-Authors: Ana Carolina Silveira, Rovilson Gilioli, Elizângela S Oliveira, Rosana A BassaniAbstract:Syphacia sp. is a common intestinal parasite in conventionally-housed laboratory rodents. Although gross lesions are rare in oxyuriasis, it is possible that more subtle changes may develop, which may affect research results. In this study, we analysed the responsiveness to β-adrenergic stimulation by isoproterenol (ISO) of left atria isolated from Syphacia-infested (SYPH) and control, non-infested adult male Wistar rats (CONT). In the non-infested animals, ISO pD2 was not significantly changed by ivermectin treatment. Whereas the maximal inotropic response to ISO was not significantly affected, the pD2 value was decreased in SYPH (7.61 ± 0.09, n = 7, vs 8.21 ± 0.25 in CONT, n = 5, P < 0.05), indicating lower sensitivity to β-adrenergic stimulation. This change was similar to that caused by a classic stressor, namely repeated immobilization, in non-infested rats (IMMO). In this group, ISO pD2 was 7.62 ± 0.14, n = 6 (P < 0.05 with relation to CONT). The results indicate that infestation with Syphacia sp. is...

the acute effects of single dose orally administered doramectin eprinomectin and selamectin on natural infections of Syphacia muris in rats
Experimental Parasitology, 2009Co-Authors: Feride Kircali Sevimli, Esma Kozan, Alper Sevimli, Nurhan Dogan, Aziz BulbulAbstract:Abstract This study was designed to determine the acute effects of a single-dose of orally administered doramectin, eprinomectin and selamectin on Syphacia muris infection in rats. Rats, naturally infected with S. muris , were divided into four groups: three different treatment groups ( n = 7) and one positive control ( n = 7). Cellophane tape preparations were obtained from the treated rats on day 0 pre-treatment and on days 2, 4 and 6 post-treatment. Syphacia sp. eggs were counted. Eprinomectin was found to be 100% effective in eliminating eggs on two post-treatment. However when egg counts on day 6 post-treatment were compared with pre-treatment egg counts, doramectin and selamectin were found to be 99.32 and 98.77% effective in eliminating eggs, respectively. On day 7 post-treatment, blood samples were obtained from all groups, and then the rats were necropsied. Doramectin, eprinomectin and selamectin were found to be 100% effective in eliminating adult S. muris , when compared with the positive control group.
