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...

This study evaluated the efficacy of two different doses of amprolium in goats heavily infected with pathogenic Eimeria species. Forty Boer goat kids ranging from 3 to 5 months of age with naturally occurring coccidiosis were randomly divided into 2 groups and treated orally with amprolium at doses of 10mg/kg daily for 5 days (n=20) or 50mg/kg daily for 5 days (n=20). The Eimeria oocyst per gra...

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...

The genus Eimeria (Apicomplexa, Coccidia) provides a wide range of different species with different hosts to study common and variable features within the genus and its species. A common characteristic of all known Eimeria species is the oocyst, the infectious stage where its life cycle starts and ends. In our study, we utilized Eimeria nieschulzi as a model organism. This rat-specific parasite...

A total of 597 faecal samples were collected from western grey kangaroos (Macropus fuliginosus), Euros (M. robustus), red kangaroos (M. rufus) in Western Australia and Eastern Grey Kangaroos (M. giganteus) from Victoria and screened for the presence of Eimeria by PCR at the 18S ribosomal RNA (rRNA) locus. The overall prevalence was 24.3% (145/597). At the 18S rRNA locus, sequences were obtained...

BACKGROUND Coccidiosis is a serious protozoal disease of poultry. The identification of Eimeria species has important implications for diagnosis and control as well as for epidemiology. The molecular characterization of Eimeria species infecting Egyptian baladi chickens was investigated. METHODS Eimeria species oocysts were harvested from intestines of naturally infected Egyptian baldi chicke...

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...

fecal samples of 60 turkey poults that showed chronic progressive symptoms like unthriftiness, loss ofweight, diarrhea were collected from the most rural areas with high rate of turkey population in north andwest part of country for intestinal protozoan parasites. according to the morphological characteristics, likeshape, presence or absence of micropyle, and/or polar granule, the 5 different t...

In order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by Eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of Eimeria (E. acervulina, E. maxima, E. necatrix, and E. tenella) at 26 days of age. There was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. Histopathological examinat...

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...
