Development of Sarcocystis falcatula in cell cultures demonstrates that it is different from Sarcocystis neurona.
The development of Sarcocystis falcatula merozoites in bovine turbinate (BT) cell cultures is described and compared with development of Sarcocystis neurona merozoites. Merozoites of S. falcatula entered BT cell cultures and increased in size until 3 days post-inoculation when the nucleus of some merozoites developed lobes. Developing schizonts present at 4 days contained a lobed nucleus or app...
متن کاملDetermination of the activity of diclazuril against Sarcocystis neurona and Sarcocystis falcatula in cell cultures.
Diclazuril is a benzeneacetonitril anticoccidial that has excellent activity against the extraintestinal stages of Toxoplasma gondii and Neospora caninum. It also is highly active against intestinal coccidia of poultry. The present study examined the efficacy of diclazuril in inhibiting merozoite production of Sarcocystis neurona and Sarcocystis falcatula in bovine turbinate cell cultures. Dicl...
متن کاملComparative development and merozoite production of two isolates of Sarcocystis neurona and Sarcocystis falcatula in cultured cells.
The development and merozoite production of Sarcocystis falcatula and 2 isolates (SN6 and SN2) of Sarcocystis neurona were studied in various cultured cell lines inoculated with culture-derived merozoites. All 3 parasites underwent multiple cycles of schizogony in VERO cells, bovine monocytes (M617 cells), and bovine pulmonary artery endothelial cells (CPA). Sarcocystis neurona strains SN6 and ...
متن کاملMolecular phylogenetic relatedness of Frenkelia spp. (Protozoa, Apicomplexa) to Sarcocystis falcatula Stiles 1893: is the genus Sarcocystis paraphyletic?
The coccidians Frenkelia microti and F. glareoli (Apicomplexa: Sarcocystidae) form tissue cysts in the brain of small rodents (intermediate hosts) while oocysts are formed in the intestine of final hosts, buzzards of the genus Buteo. The inclusion of the small subunit ribosomal RNA gene sequences (SSU rRNA) of both Frenkelia species into the SSU rRNA trees of other, tissue cyst-forming coccidia...
متن کاملDevelopment of Sarcocystis falcatula in its intermediate host, the Brown-headed Cowbird (Molothrus ater).
Sporocysts of Sarcocystis falcatula obtained from experimentally infected Virginia opossums (Didelphis virginiana) were inoculated orally to 60 wild-caught Brown-headed Cowbirds (Molothrus ater). Another 30 Brown-headed Cowbirds were not challenged and served as uninfected controls. Two inoculated and one control cowbird were necropsied every 2 weeks and the pectoral and thigh muscles were exam...
