With the Eimeria spp. populations that infect chickens used as a model for coccidian biology, we aimed to survey the transcriptome of Eimeria maxima and contrast it to the 2 other Eimeria spp. for which transcriptome data are available, i.e., Eimeria tenella and Eimeria acervulina .

Studies on Eimeria mivati in chickens and a comparison with Eimeria acervulina
Journal of Comparative Pathology, 1967Abstract Eimeria mivati was isolated from fowls in Britain. Heavy experimental infections caused some morbidity and had a marked effect on gain in body weight. Evidence is presented which suggests that the breed or strain of the host influences the degree of pathogenicity.

Eimeria acervulina, E. necatrix, E. brunetti and E. tenella were found to be widely distributed in north-east Georgia. 2. Using immunity challenge techniques 17 flocks from 12 to 72 weeks of age showed significantly lower lesion scores for the first three species compared with susceptible control flocks similarly challenged. Only one flock was found to

Detection and assessment of sublethal infections of Eimeria tenella and Eimeria necatrix
Experimental Parasitology, 1960Abstract 1. 1. The estimation of the packed red-cell volume by the micro-hematocrit technique proved to be a convenient method of measuring anemia in chickens infected with E. tenella or E. necatrix . 2. 2. Hematocrit measurements were more sensitive to the effects of infection with E. tenella than observations on the growth rate. 3.

Eimeria sceloporis and Eimeria molochis spp. n. from Lizards
The Journal of Parasitology, 1965Two new species of coccidia are described: Eimeria sceloporis sp. n. in the small intestine of lizards (Sceloporus spp.) from southern California and Mexico; and Eimeria molochis sp. n. in the Australian "horned toad," Moloch horridus, from the Queensland desert, probably also an intestinal parasite. The oocyst of E.

Previous studies revealed an ameliorating effect of Eimeria praecox on concurrent E. maxima infection, such that weight gain, feed conversion ratio, and intestinal lesions were nearly identical to uninfected or E. praecox-infected controls. The purpose of the present study was to determine if protective immunity against E.

Vaccine, 2015
Avian coccidiosis is mostly caused by mixed infection of several Eimeria species under natural conditions and immunity to avian coccidiosis is largely dependent on T-cell immune response. In this study, 14 T-cell epitope fragments from eight antigens of Eimeria tenella (E. tenella), Eimeria necatrix (E. necatrix), Eimeria maxima (E. maxima) and Eimeria

Outbreaks of avian coccidiosis may occur when susceptible chickens are raised on litter containing viable Eimeria oocysts. The purpose of this study was to compare the relative sensitivities of Eimeria acervulina, Eimeria maxima, and Eimeria tenella oocysts to dessication. Sporulated E. acervulina, E. maxima, or E.

After 6 to 8 months of storage, cultures of sporulated Eimeria acervulina and E. tenella oocysts ahd a marked drop in the number of sporocysts that survived grinding, sporozoites that survived after excystation, and sporozoites that penetrated chick kidney cells in vitro. The rate of excystation was unaffected by storage of up to one year.

Studies of resistance to anticoccidials in Eimeria field isolates and pure Eimeria strains
Veterinary Parasitology, 1997Ten Eimeria field isolates from North Germany were studied in battery tests for sensitivity to selected anticoccidials. A high percentage of the Eimeria field isolates (9 out of 10) showed resistance to anticoccidials, mostly multiple resistance.
