Studies on site finding and site specificity of Eimeria praecox, Eimeria maxima and Eimeria acervulina in chickens

open access: yesParasitology, 1976
Sporozoites of 3 species of Eimeria were introduced into the caecum of young chickens. E. praecox and E. maxima failed to develop in this site, but light infections of E. acervulina were detected. Infection of the small intestine with all 3 species occurred when sporozoites were introduced via the caecum.Infections were produced when mucosal scrapings ...

Vaccination with transgenic Eimeria tenella expressing Eimeria maxima AMA1 and IMP1 confers partial protection against high level E. maxima challenge in a broiler model of coccidiosis. [PDF]

open access: yes, 2020
Poultry coccidiosis is a parasitic enteric disease with a highly negative impact on chicken production. In-feed chemoprophylaxis remains the primary method of control, but the increasing ineffectiveness of anticoccidial drugs, and potential future ...

The development of drug-resistant strains of Eimeria maxima in the laboratory

open access: yesParasitology, 1975
The development of strains of Eimeria maxima resistant to buquinolate, methyl benzoquate, clopidol, sulphaquinoxaline and robenidine is described. It was not possible to standardize a schedule of inoculations and drug administration, which would enable the development of resistance to the different drugs to be compared directly.

Scanning and transmission electron microscopy ofEimeria maximamicrogametogenesis

open access: yesParasitology, 1981
SUMMARYThe structure and development of microgametocytes ofEimeria maximafrom chicks killed during the 6th day of infection were examined using transmission and scanning electron microscopy. Initially, nucleoli disappear and the surface of the microgametocyte invaginates.
