| [sarcocystis cruzi (protozoa: apicomplexa: sarcocystiidae) infection in european bison (bison bonasus) from białowieza forest, poland]. | samples of oesophagus, diaphragm and heart muscles were taken from one european bison from białowieza forest during seasonal european bison elimination in 2008. five gram of each muscle was examined by staining small samples in 0.2% aqueous solution of methylene blue. after that they were placed between compressor glasses and examined under a dissecting microscope in order to detect sarcocystis sp. infection. all sarcocysts observed were counted. the 5-g sample of the heart muscle yielded a tota ... | 2009 | 19579782 |
| sarcocystosis in neonatal bison fed sarcocystis cruzi sporocysts derived from cattle. | a 6-day-old female (bison bison) was inoculated with 10 million sporocysts of the b1 isolate of sarcocystis cruzi originally obtained by feeding heart of a naturally infected cow (bos taurus) to a laboratory-raised coyote. the bison became febrile, lethargic, and anorectic at about 25 days after inoculation of the sporocysts, and was euthanatized 3 days later. there were widespread hemorrhages, hepatitis, myocarditis, nephritis, and enteritis; intravascular meronts were found in the adrenal cort ... | 1982 | 6816777 |
| the parasitic fauna of the european bison (bison bonasus) (linnaeus, 1758) and their impact on the conservation. part 1. the summarising list of parasites noted. | during the current century, 88 species of parasites have been recorded in bison bonasus. these are 22 species of protozoa (trypanosoma wrublewskii, t. theileri, giardia sp., sarcocystis cruzi, s. hirsuta, s. hominis, s. fusiformis, neospora caninum, toxoplasma gondii, cryptosporidium sp., eimeria cylindrica, e. subspherica, e. bovis, e. zuernii, e. canadensis, e. ellipsoidalis, e. alabamensis, e. bukidnonensis, e. auburnensis, e. pellita, e. brasiliensis, babesia divergens), 4 trematodes species ... | 2014 | 25119348 |
| characterization of bovine sarcocystis species by analysis of their 18s ribosomal dna sequences. | two sarcocystis hirsuta isolates from 2 cattle (bos taurus), 2 sarcocystis hominis-like isolates from 2 cattle, 1 each sarcocystis hominis-like isolate from a zoo-born dwarf zebu (b. taurus) and from a zoo-born bison (bison bison), and 1 each sarcocystis cruzi isolate from the dwarf zebu and the bison have been characterized by comparing the directly sequenced polymerase chain reaction products of their 18s rrna genes. sequences of 2 different isolates from the same species always showed a very ... | 1998 | 9488337 |
| sarcocystis cruzi infection in wood bison (bison bison athabascae). | endangered wood bison (bison bison athabascae) is the largest terrestrial mammal in the american continent. animal health is an important issue in their conservation, and sarcocystis cruzi may be a cause of clinical disease in bovidae. hearts of eight wood bison from alaska, usa were examined for sarcocysts by histology, transmission electron microscopy, pepsin digestion, and molecularly. sarcocystis bradyzoites were found in pepsin digests of all eight and sarcocysts were found in histologic se ... | 2015 | 25868849 |
| the wisent (bison bonasus, bovidae) as an intermediate host of three sarcocystis species (apicomplexa: sarcocystidae) of cattle. | sarocysts were found in muscle tissue of a wisent (bison bonasus) which was born and kept in germany. light microscopic and tem examination revealed all the three named species known from cattle: sarcocystis cruzi ("thin-walled", with longer hair-like villar protrusions of the primary cyst wall); s. hirsuta ("thick-walled", with tongue-like protrusions of the cyst wall arising with very short and narrow stalklets from the surface of the cyst and containing rows of electron-dense granules in the ... | 1994 | 7927061 |
