Direct, reverse transcriptase-mediated, partial sequencing of the small-subunit (16S-like) ribosomal RNA (srRNA) of Eimeria tenella and E. acervulina was performed. Sequences were aligned by eye with six previously published, partial or complete srRNA sequences of apicomplexan protists (Plasmodium berghei, Theileria annulata, Cryptosporidium sp., Toxoplasma gondii, Sarcocystis muris, and S. gig...
The intermediate hosts for Sarcocystis rileyi (Stiles 1893) Minchin 1913 are ducks (Anas spp.), and the striped skunk (Mephitis mephitis) is its definitive host. The structure of sarcocysts from an experimentally infected shoveler duck (Anas cylpeata) fed sporocysts from an experimentally-infected M. mephitis was studied and compared with type specimens from a naturally infected duck. The exper...
The infection status of harbor seals Phoca vitulina in central California, USA, was evaluated through broad surveillance for pathogens in stranded and wild-caught animals from 2001 to 2008, with most samples collected in 2007 and 2008. Stranded animals from Mendocino County to San Luis Obispo County were sampled at a rehabilitation facility: The Marine Mammal Center (TMMC, n = 175); wild-caught...
ABSTRACT: This study assessed microscopic morphology of protozoan and metazoan parasites, as well parasite-associated histopathologic changes in five Brazilian free-ranging armadillos. Three armadillos had intra sarcolemmal cysts Sarcocystis sp. skeletal muscles without changes. One Dasypus novemcinctus was found parasitized with a nematode morphologically compatible an oxyurid the small intest...
Infection with Sarcocystis species is common in herbivores but is rare in bears. Histological sections of 374 black bears (Ursus americanus) from Pennsylvania were examined for sarcocysts. In total, 3 sarcocysts were found in 3 bears, with 1 sarcocyst per section. Sarcocysts from 2 bears were considered a new species, Sarcocystis ursusi. Sarcocysts of S. ursusi n. sp. were microscopic and conta...
