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...

Subclinical bovine coccidiosis is an economic problem worldwide because they appear normal outwardly, but developmental stages damage the absorptive surface of the intestine and weaken the immune system. Information on the occurrence, diversity and economic losses due to Eimeria infection in cattle is lacking in Al-Baha area. The objective of this work was to study prevalence of subclinical bov...

Challenge infections with 10(3), 5 x 10(4), 10(5), or 5 x 10(5) sporulated Eimeria praecox oocysts caused moderate but significant weight gain reduction at all infective doses. Substantial reduction in plasma carotenoids and moderate but significant increases in plasma NO2(-) + NO3- were observed only at the two higher doses when measured at day 6 postchallenge (PC). Daily monitoring of chicken...

One group of kids (n = 23) was given 2 x 10(5) oocysts of Eimeria ovinoidalis (sheep coccidia) at birth; a second group (n = 23) was kept as an uninoculated control. Body weights, E ninakohlyakimovae oocyst output and serum coccidial antibody levels were monitored up to 77-102 d of age. No significant difference in any of these parameters was seen between the 2 groups, suggesting that no immune...

background: coccidian infection in poultry is the most common infection in the world and is the cause of mortality and great economic losses in poultry production. objectives: this study was aimed to determine the frequency and eimeria species diversity in broiler farms of hamadan suburb, iran. methods: a total of 16 broiler farms were randomly selected with different production age in 2012. th...

In this study, gerbils collected in the Mongolia over the summers of 2009-2012 were examined for coccidia. In total, 171 gerbils of three species from 22 localities were examined for coccidia. Coccidian oocysts were identified from 21 gerbils, but those found in 1 of those gerbils were probably pseudoparasites of the host from which they were recovered. From the remaining 20 gerbils, 7 morphoty...

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...

Caprine coccidiosis, protozoan disease caused by Eimeria species, is major parasitic diseases characterized by contagious enteritis. Severity of Eimeria spp. infection is more in young animals. Two goat kids aged below one year died with history of mucoid to haemorrhagic yellow watery diarrhea, anorexia, emaciation, poor growth and death. At necropsy, gross lesions in intestines revealed diffus...

The in vitro production of gametocytes and oocysts of the apicomplexan parasite genus Eimeria is still a challenge in coccidiosis research. Until today, an in vitro development of gametocytes or oocysts had only been shown in some Eimeria species. For several mammalian Eimeria species, partial developments could be achieved in different cell types, but a development up to gametocytes or oocysts...

The purpose of the present study was to evaluate the species composition and salinomycin sensitivity of Eimeria oocysts isolated from commercial broiler farms that differed by means of coccidiosis control (anticoccidial drugs [ACD] vs. live oocyst vaccines [VAC]). A comparison of Eimeria species composition and salinomycin sensitivity was also made before and after a producer switched from sali...
