During the summers of 2000, 2001, and 2002, 1,950 fecal samples from 4 families, 10 genera, and 16 species of rodents in Alaska, U.S.A. (N1⁄41,711), and Siberia, Russia (N1⁄4239) were examined for coccidia (Apicomplexa: Eimeriidae). The 4 families sampled were Dipodidae (jumping mice), Erethizontidae (New World porcupines), Muridae (mice, rats), and Cricetidae (voles, lemmings). Nineteen oocyst...

A cross-sectional study was carried out to determine the prevalence, species characterization and associated risk factors with Eimeria (E.) in sheep of district Toba Tek Singh from April, 2009 to March, 2010. Of the total 486 faecal samples examined for Eimeria, 209 (43%) were found infected with five species of Eimeria. Amongst the identified species of Eimeria, E. ovinoidalis was the commones...

Faecal samples collected from 300 Bolivian marsupials (Didelphimorphia: Didelphidae) between 1984 and 1993 were examined for coccidian parasites. Sporulated oocysts were present in the faeces of 50 (17%) marsupials representing 11 genera and 22 species. Three new species of Eimeria are described and named from six host species. One species occurred in Marmosops dorothea, Monodelphis domestica a...

background: eimeria infection is an important part of protozoal infection in ruminants which causes economic lost in animal husbandry of iran and worldwide. therefore it is important to implement effective control programs on the prevalence and diversity of eimeria species in livestocks. objectives: this study was aimed to determine prevalence and eimeria species diversity in dairy cattle with ...

A cross-sectional study was carried out to determine the prevalence, species composition, and associated risk factors with Eimeria infection in calves of 40 dairy farms in Addis Ababa city and Debre Zeit town. Of the total 580 calves examined for Eimeria infection, 68.1% (395) were infected with 1 or more Eimeria species. A total of 11 species of Eimeria were identified. The most prevalent was ...

BACKGROUND Coccidiosis is an intestinal disease of chickens caused by various species of protozoan parasites within the genus Eimeria. Diagnosis and genetic characterization of different species of Eimeria are central to the prevention, surveillance, and control of coccidiosis. The aim of this study was to detect different chicken Eimeria species from several areas in Khuzestan, southwest Iran....

Fecal samples from arctic ground squirrels (Spermophilus parryii) collected in Alaska (n = 90) and Russia (n = 46) and from red squirrels (Tamiasciurus hudsonicus) in Alaska (n = 35) were examined for the presence of Eimeria spp. (Apicomplexa: Eimeriidae). Four species were recovered from arctic ground squirrels, including Eimeria callospermophili (prevalence = 18%), Eimeria cynomysis (23.5%), ...

background: coccidiosis is a serious protozoal disease of poultry. the iden-tification of eimeria species has important implications for diagnosis and con-trol as well as for epidemiology. the molecular characterization of eimeria spe-cies infecting egyptian baladi chickens was investigated. methods: eimeria species oocysts were harvested from intestines of naturally infected egyptian baldi chi...

Human-associated Cyclospora is a coccidian parasite that causes diarrheal disease. A reevaluation of the parasite's molecular taxonomy that takes into account newly published data for seven Eimeria species shows that Cyclospora belongs to the Eimeria clade (Eimeriidae family). The Cyclospora branch on the phylogenetic tree is between the branches of the eight avian and two mammalian Eimeria spe...

A full-length cDNA encoding chicken tumor necrosis factor superfamily 15 (TNFSF15) was isolated and its functional role was investigated. TNFSF15 transcripts were primarily expressed in spleen, liver, intestinal intraepithelial lymphocytes (IEL), peripheral blood lymphocytes and bursa. In vitro infection of HTC macrophages with three species of Eimeria sporozoites induced TNFSF15 gene expressio...
