Superoxide dismutases in Eimeria tenella
Molecular and Biochemical Parasitology, 1991Unsporulated oocysts of Eimeria tenella have high superoxide dismutase (SOD: superoxide:superoxide oxidoreductase, EC 1.15.1.1.) activity and contain several electrophoretically distinct forms of the enzyme, including two forms of Cu/Zn-containing SOD, two forms of Fe-SOD and two forms of Mn-SOD. SOD activity remains high during 12 h of sporulation but

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.

Attenuation of Eimeria species: further characterisation of two lines of Eimeria mitis
Research in Veterinary Science, 1985The immunogenicity of a 'precocious' and attenuated line (HP10) of Eimeria mitis was studied and the stability of attenuation of two precocious lines was compared with that of an embryo-adapted line. Chicks housed in wire-floored cages and given 1 X 10(5) oocysts of the HP10 line were protected against challenge with the parent Houghton strain and two ...

Avian diseases, 1982
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.

KNOWLEDGE of the early development of Eimeria stiedae, before the appearance of trophozoites in the liver of its rabbit host, is remarkably scanty. After initial penetration of the duodenal epithelium by the sporozoites, the earliest observation of trophozoite formation has been 72 h after infection.

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.
