The microbial diversity of wastewater used for irrigation and fertilization was assessed using specific polymerase chain reaction (PCR) assays to detect and genotype several pathogenic protists including Cryptosporidium spp., Giardia duodenalis, Cyclospora spp., Eimeria spp. and Enterocytozoon bieneusi. A total of 220 wastewater samples (110 raw, 110 treated) and 12 sludge samples were collecte...

Partial plastid 23S and nuclear 18S rDNA genes were amplified and sequenced from 2 morphologically similar Eimeria species. E. antrozoi from a bat (Antrozous pallidus) and E. arizonensis from deer mice (Peromyscus spp.), as well as some other Eimeria species from bats and rodents. The phylogenetic trees clearly separated E. antrozoi from E. arizonensis. The phylogenies based on plastid 23S rDNA...

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%), ...

A total of 598 buffaloes were sampled for both coprological (210) and haematological (388) investigations at the Large Animal Clinics, GADVASU, Ludhiana, Punjab, India. Coprological examination revealed that the overall prevalence of gastrointestinal (GI) parasitic infections was 23.33% (49/210). Among the revealed parasites, amphistomes, Fasciola spp., Eimeria spp., Balantidium coli and strong...

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...

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 ...

This study was undertaken to determine the prevalence and diversity of Eimeria species in sheep in Tabriz suburb. The prevalence of ovine parasitism due to Eimeria spp. was estimated in 240 sheep aged less than six months to over 12 months, in a period of one year (2003-2004). The samples were collected from pre-slaughtered sheep in Tabriz slaughterhouse and transferred to the parasitology labo...

Parasites are important productionlimiting diseases in livestock farming. Their proper treatment and control requires knowledge of their presence, epidemiology, and diagnostics. We investigated the presence of the GI parasites in pooled herd faecal samples from the islands Saaremaa (n=21), Hiiumaa (n=18), and Vormsi (n=7), collected in 2011–2012. The samples were investigated microscopically af...

Parasitology Research Group, Centre for Communicable Diseases, ICDDR,B, Dhaka, Bangladesh To investigate the prevalence of gastrointestinal parasites of calves, 450 feacal samples were collected from Mirsarai Upazilla of Chittagong District of Bangladesh during the period from 2011 to 2012. Fecal samples of calves aged up to 6 months of three different genotypes were examined for gastrointestin...

This study aims to investigate the occurrence of gastrointestinal parasites in goats from the Western Santa Catarina, Brazil. Twenty four farms were analyzed in 17 different municipalities. Animals (n=217) from different production purposes (milk and meat) and age were randomly chosen. Fecal samples were collected from the rectum stored in plastic bottles and transported to the laboratory in po...
