| sarcocystis in the birds family corvidae with description of sarcocystis cornixi sp. nov. from the hooded crow (corvus cornix). | having studied 67 birds of six species of the family corvidae, sarcocystis cysts were found in 16 (23.9%) individuals belonging to three species. the highest prevalence of infection (35.9%) was determined in the hooded crow (corvus cornix). two types of sarcocysts, which were temporarily called cysts type i and type v, were determined in the corvids examined. by light microscope, type i cyst wall seemed to be thin (< 1.0 microm) and smooth. banana shaped cystozoites measured 6.0-8.0 microm in le ... | 2009 | 18855013 |
| accipiter hawks (accipitridae) confirmed as definitive hosts of sarcocystis turdusi, sarcocystis cornixi and sarcocystis sp. ex phalacrocorax carbo. | sarcocystis is a large genus of protozoan parasites with complex heteroxenous life cycles. for many species, either the intermediate or the definitive host is still unknown. in this study, 116 accipiter hawks (eurasian sparrowhawks and northern goshawks) were investigated for the presence of sarcocystis spp. in their intestinal tract or their faeces. to gain a wide distribution, samples were collected throughout germany within 2 years. it was possible to detect sarcocystis-like oocysts in 65 sam ... | 2016 | 27083188 |
