We analyzed almost complete 18S rDNA sequences of 10 bovine Eimeria species, namely Eimeria alabamensis, E. auburnensis, E. bovis, E. bukidnonensis, E. canadensis, E. cylindrica, E. ellipsoidalis, E. subspherica, E. wyomingensis and E. zuernii. Although these sequences showed intraspecific variation in 8 species, the sequences of each species were clustered in monophyletic groups in all species...
The present study was designed to investigate the prevalence of Eimeria spp. in Zabol, east of Iran. The samples were examined microscopically for the presence of oocysts from February 2015 to December 2016. Out of 196 cattle, 124 (63.26%) were identified to be positive for Eimeria species. Eight species of Eimeria were found as follows: E. bovis (42.54%), E. zuernii (38.67%), E. subspherica (5...
The efficacy of three polyether ionophores viz. salinomycin, monensin and maduramicin was evaluated in poultry. Dayold chicks (n=350) were randomly divided into seven groups of 50 chicks each. The drugs were administered as feed premix from day one onwards. The chicks at 14-day of age were initially infected with 20,000 sporulated viable oocysts of Eimeria tenella and challenged with 40,000 spo...
Loószová A., V. Revajová, M. Levkut, J . Pist l: Pathogenesis of Eimeria colchici in the Intestine of Chickens and the Related Immune Response. Acta Vet. Brno 2001, 70: 191-196. To study the immune response in poultry, a non-specific host for pheasant Eimeria colchici coccidium, ten-day-old chickens were each orally inoculated with 106 oocysts. For determination and comparison of coccidia invas...
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%), ...
Coccidian Parasites and Conservation Implications for the Endangered Whooping Crane (Grus americana)
While the population of endangered whooping cranes (Grus americana) has grown from 15 individuals in 1941 to an estimated 304 birds today, the population growth is not sufficient to support a down-listing of the species to threatened status. The degree to which disease may be limiting the population growth of whooping cranes is unknown. One disease of potential concern is caused by two crane-as...
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....
Penelitian yang dilaksanakan pada Oktober 2022 bertujuan untuk mengetahui tingkat infestasi dan jenis parasit saluran pencernaan Sapi Peranakan Simental di Kecamatan Tulang Bawang Udik, Kabupaten Barat. Metode penelitian digunakan adalah metode survei. Jumlah sampel diperoleh yaitu 113 berasal dari 71 peternak. Pemeriksaan feses sapi dilakukan Balai Veteriner, Kota Bandar Lampung menggunakan Mc...
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...
