The adverse effects of parasitic gastrointestinal diseases on poultry production are enormous, especially where birds kept under extensive or semi-intensive systems, but the rarely recognized as primary problems except during necropsy examinations. A two-year longitudinal cohort prospective study was conducted from October 2018 to September 2020 determine prevalence and diagnostic features in V...

An intestinal Eimeria was previously reported as a significant pathogen of Asian seabass (Lates calcarifer) in nurseries in Vietnam. In the present study, both Eimeria and Cryptosporidium were detected by sequence analyses of fragments of the 18S rRNA gene amplified from these Vietnamese L. calcarifer tissues. Based on these analyses, the Eimeria from the Vietnamese L. calcarifer formed clades ...

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...

Interleukin-10 (IL-10) mRNA levels are increased within intestinal mucosa after Eimeria infection. IL-10 apical receptor presence on enterocytes suggests IL-10 is secreted into the intestinal lumen. Increased IL-10 has been shown to be central to the pathogenesis of numerous intracellular pathogens; we hypothesize luminal secretion of IL-10 enables Eimeria spp. infection in chickens. This study...

BACKGROUND Coccidiosis, caused by species of the apicomplexan parasite Eimeria, is a major disease of chickens. Eimeria species are present world-wide, and are ubiquitous under intensive farming methods. However, prevalence of Eimeria species is not uniform across production systems. In developing countries such as Ethiopia, a high proportion of chicken production occurs on rural smallholdings ...

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...
