Beginning in July 1980, 149 voles (Microtus spp.) representing 9 species and 14 subspecies collected in Japan, Mexico and the United States were examined for coccidia; 67 (45%) had oocysts in their feces. These included 1 of 3 (33%) M. californicus sactidiegi; 0 of 1 M. longicaudus longicaudus; 0 of 1 M. l. macrurus; 48 of 111 (43%) M. mexicanus including 11 of 26 (42%) M. m. fulviventer, 1 of ...

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 ...

Parasites of the genus Eimeria infect a wide range of vertebrate hosts, including chickens. We have recently reported a comparative analysis of the transcriptomes of Eimeria acervulina, Eimeria maxima and Eimeria tenella, integrating ORESTES data produced by our group and publicly available Expressed Sequence Tags (ESTs). All cDNA reads have been assembled, and the reconstructed transcripts hav...

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...

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%), ...

intestinal coccidiosis, caused by eimeria species, is an economically-important disease of poultry production industry worldwide. this study was designed to investigate the prevalence of different eimeria species in the farmed broilers of khoy city, west azarbaijan, north west iran. a total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. in...

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...

Coccidiosis is recognized as the major parasitic disease of poultry and is caused by the apicomplexan protozoa Eimeria. Increasing evidence shows the complexity of the host immune response to Eimeria and microarray technology presents a powerful tool for the study of such an intricate biological process. Using an avian macrophage microarray containing 4906 unique gene elements, we identified im...
