Leptospira borgpetersenii from free-living white-eared opossum (Didelphis albiventris): first isolation in Brazil.
Acta tropica, 2012Co-Authors: Sérgio Jorge, Cláudia Pinho Hartleben, Fabiana Kömmling Seixas, Marco Antonio Afonso Coimbra, Cledir B. Stark, Adriana G. Larrondo, Marta G. Amaral, Ana Paula Neuschrank Albano, Luiz Fernando Minello, Odir Antonio DellagostinAbstract:Leptospirosis is a zoonotic disease that occurs all over the world, caused by bacteria of the genus Leptospira. Marsupial and didelphidae families are considered susceptible to infection caused by a wide range of Leptospira serovars for which they serve as reservoirs. Thirty-three free-living white-eared opossums (Didelphis albiventris) were captured in Southern Brazil and bodily fluids were collected. From the urine samples it was possible to obtain an isolate identified as Leptospira borgpetersenii by rpoB gene sequencing and belonging to serovar Castellonis by Multilocus Variable-Number Tandem-Repeat Analysis. This is the first report of the isolation of Leptospira spp. from the white-eared opossum in Brazil. In addition, the new strain was also virulent in the hamster model of lethal leptospirosis. The microscopic agglutination test (MAT) was used for detecting the presence of antibodies against Leptospira spp. in white-eared opossum, human, cattle and canine sera using a panel of 59 Leptospira strains that included the new isolate. The inclusion of the new strain in the MAT battery increased the MAT sensitivity for canine sera. These findings suggest that the white-eared opossum is an important reservoir of pathogenic Leptospira spp.

isolates of sarcocystis falcatula like organisms from south american opossums Didelphis marsupialis and Didelphis albiventris from sao paulo brazil
Journal of Parasitology, 2001Co-Authors: J P Dubey, David S Lindsay, O C H Kwok, Benjamin M Rosenthal, Claudia Ehlers Kerber, Nobuko Kasai, H F J Pena, S K ShenAbstract:Isolates of Sarcocystis falcatula–like organisms from South American opossums were characterized based on biological and morphological criteria. Sporocysts from intestinal scrapings of 1 Didelphis marsupialis and 8 Didelphis albiventris from Sao Paulo, Brazil, were fed to captive budgerigars (Melopsittacus undulatus). Budgerigars fed sporocysts from all 9 isolates became ill and S. falcatula–like schizonts were identified in sections of their lungs by immunohistochemical staining. Sarcocystis falcatula–like organisms were cultured from lungs of budgerigars fed sporocysts from D. marsupialis and from lungs of budgerigars fed sporocysts from 3 of 8 D. albiventris. The 33/54 locus amplified by polymerase chain reaction from culture-derived merozoites contained both a HinfI endonuclease recognition site previously suggested to diagnose S. falcatula and a DraI site thought to diagnosed S. neurona. Development of the isolate from D. marsupialis was studied in cell culture; its schizonts divided by endopolygeny,...

sarcocystis lindsayi n sp protozoa sarcocystidae from the south american opossum Didelphis albiventris from brazil
Journal of Eukaryotic Microbiology, 2001Co-Authors: J P Dubey, Benjamin M Rosenthal, C. A. SpeerAbstract:Abstract A new species, Sarcocystis lindsayi n. sp., is proposed for a parasite resembling Sarcocystis falcatula. It was obtained from the lungs and muscles of budgerigars (Melopsittacus undulatus) fed sporocysts from a naturally-infected South American opossum, Didelphis albiventris, from Jaboticabal, Brazil. Sarcocysts of S. lindsayi n. sp. in budgerigars are microscopic, up to 600 μm long and up to 50 μm wide. The cyst wall is up to 2 μm thick. Ultrastructurally, the sarcocyst wall consists of numerous slender villar protrusions (up to 2.0 μm long and up to 0.3 μm wide), each with a stylet at its tip. Schizonts in cell culture divide by endopolygeny leaving a residual body. Sporocysts are ∼ 12 × 7 μm. The parasite is genetically distinct from other organisms that also cycle between opossums and avian species and resemble S. falcatula. Diagnostic genetic variation has been observed in the nuclear large subunit ribosomal RNA gene, the internal transcribed spacer (ITS-1), and each of two other genetic loc...

first isolation of sarcocystis neurona from the south american opossum Didelphis albiventris from brazil
Veterinary Parasitology, 2001Co-Authors: J P Dubey, Solange Maria Gennari, Hilda Fatima De Jesus Pena, David S Lindsay, O C H Kwok, Claudia Ehlers Kerber, Nobuko Kasai, Benjamin M RosenthalAbstract:Sarcocystis neurona was isolated from sporocysts from two of eight South American opossums, Didelphis albiventris, from Brazil. Interferon gamma gene knock out (KO) mice fed sporocysts from two opossums developed neurologic sarcocystosis. S. neurona was demonstrated in the brains of infected KO mice by immunohistochemical staining with anti-S. neurona antibody. The parasite was cultivated in cell culture and S. neurona DNA was isolated from cultured merozoites. This is the first report of isolation of S. neurona from Brazil and the first report from its new host, D. albiventris.

isolation of sarcocystis speeri dubey and lindsay 1999 parasite from the south american opossum Didelphis albiventris from argentina
Journal of Parasitology, 2000Co-Authors: J P Dubey, C. A. Speer, L Venturini, M C VenturiniAbstract:Sarcocystis sporocysts from the intestines of 2 opossums (Didelphis albiventris) from Argentina were fed to gamma-interferon knockout (KO) and nude mice. Protozoal schizonts were seen in brain, liver, spleen, and adrenal glands of mice examined 33-64 days after feeding sporocysts. Sarcocysts were seen in skeletal muscles of KO mice 34-71 days after feeding sporocysts. Schizonts and sarcocysts were structurally similar to Sarcocystis speeri Dubey and Lindsay, 1999 seen in mice fed sporocysts from the North American opossum Didelphis virginiana from the United States.

Experimental Transmission of Sarcocystis speeri Dubey and Lindsay, 1999 from the South American Opossum (Didelphis albiventris) to the North American Opossum (Didelphis virginiana)
The Journal of parasitology, 2000Co-Authors: J P Dubey, C. A. Speer, Dwight D. Bowman, K. M. Horton, Cecilia Venturini, L VenturiniAbstract:Sarcocystis speeri Dubey and Lindsay, 1999 from the South American opossum Didelphis albiventris was successfully transmitted to the North American opossum Didelphis virginiana. Sporocysts from a naturally infected D. albiventris from Argentina were fed to 2 γ-interferon knockout (KO) mice. The mice were killed 64 and 71 days after sporocyst feeding (DAF). Muscles containing sarcocysts from the KO mouse killed 71 DAF were fed to a captive D. virginiana; this opossum shed sporocysts 11 days after ingesting sarcocysts. Sporocysts from D. virginiana were fed to 9 KO mice and 4 budgerigars (Melopsittacus undulatus). Schizonts, sarcocysts, or both of S. speeri were found in tissues of all 7 KO mice killed 29–85 DAF; 2 mice died 39 and 48 DAF were not necropsied. Sarcocystis stages were not found in tissues of the 4 budgerigars fed S. speeri sporocysts and killed 35 DAF. These results indicate that S. speeri is distinct from Sarcocystis falcatula and Sarcocystis neurona, and that S. speeri is present in both D....

characterization of an unidentified sarcocystis falcatula like parasite from the south american opossum Didelphis albiventris from brazil
Journal of Eukaryotic Microbiology, 2000Co-Authors: J P Dubey, David S Lindsay, P C B Rezende, A J CostaAbstract:An unidentified isolate of a Sarcocystis falcatula-like parasite was obtained from the lungs of budgerigars (Melopsittacus undulatus) fed sporocysts from a naturally-infected South American opossum, Didelphis albiventris from Brazil. Four captive budgerigars fed sporocysts from the opossum intestine died of acute sarcocystosis 8, 10, and 12 days after oral inoculation (DAI); one budgerigar was killed 12 DAI when it was lethargic. Schizonts and merozoites found in the lungs of the budgerigars reacted mildly with polyclonal S. falcatula antibody. The parasite was isolated in equine kidney cell cultures inoculated with lung tissue from a budgerigar that was killed 12 DAI. Two budgerigars inoculated subcutaneously with 100,000 culture-derived S. falcatula merozoites developed acute sarcocystosis and S. falcatula-like schizonts were found in their lungs 15 and 16 DAI. Four budgerigars kept as unfed controls in the same environment remained free of Sarcocystis infection. The parasite underwent schizogony in African green monkey kidney cells and bovine turbinate cells. Merozoites divided by endopolygeny, often leaving a residual body. Polymerase chain reaction studies using primers JNB33/JNB54 and Hinf I and Dra I digestion indicated that the isolate was not S. falcatula. Results of this study indicated that the South American opossum, D. albiventris, is a definitive host for yet another S. falcatula-like parasite.

characterization of sarcocystis falcatula isolates from the argentinian opossum Didelphis albiventris
Journal of Eukaryotic Microbiology, 2000Co-Authors: J P Dubey, David S Lindsay, L Venturini, C VenturiniAbstract:Two isolates of Sarcocystis falcatula were obtained from the lungs of budgerigars (Melopsittacus undulatus) fed sporocysts from two naturally-infected South American opossums (Didelphis albiventris). The two isolates were designated SF-1A and SF-2A. Both isolates induced fatal infections in budgerigars. Both isolates underwent schizogony in African green monkey kidney cells. The structure of schizonts in the lungs of budgerigars was more variable than that observed in cell culture. The two isolates were identified as S. falcatula by the two species-specific Hinf 1 restriction fragments dervied from digestion of a PCR amplification using primers JNB33/JNB54. Thus, the South American opossum, D. albiventris, is a definitive host for S. falcatula.

isolation of sarcocystis falcatula from the south american opossum Didelphis albiventris from argentina
Veterinary Parasitology, 1999Co-Authors: J P Dubey, L Venturini, Cecilia Venturini, W Basso, Juan Manuel UnzagaAbstract:Abstract Sarcocystis sporocysts from the intestines of four opossums (Didelphis albiventris) from Argentina were identified as Sarcocystis falcatula based on schizogonic stages and pathogenicity to budgerigars (Melopsittacus undulatus). Seven budgerigars fed sporocysts from the opossum feces died of acute sarcocystosis 8, 9, 11, 12, and 14 days after inoculation. Schizonts and merozoites found in the lungs and other organs of the budgerigars were identified as S. falcatula based on structure and immunoreactivity with S. falcatula-specific antibody. Sarcocystis falcatula was also isolated in bovine monocyte cell cultures inoculated with lung tissue from a budgerigar that died nine days after ingesting sporocysts. Two budgerigars inoculated subcutaneously with 1 000 000 culture-derived S. falcatula died 11 and 12 days post-inoculation. This is the first report of S. falcatula infection in South America.
