The sexual (macrogamete/macrogametocyte) stage antigen, GAM82, in the apicomplexan parasite Eimeria maxima, has an apparent molecular mass of 82 kDa, and has been implicated in protective immunity against coccidiosis in poultry. The gene encoding this protein, gam82, was cloned and sequenced. It is
Eimeria species, of the Phylum Apicomplexa, cause the disease coccidiosis in poultry, resulting in severe economic losses every year. Transmission of the disease is via the faecal-oral route, and is facilitated by intensive rearing conditions in the poultry industry. Additionally, Eimeria has
20-day old chicks were infected with Eimeria tenella, treated with coccidin (250 mg/kg) and free amino acids of the femoral muscle tissues were studied. The infection of chicks was accompanied with metabolism disorders of all amino acids of the muscle tissue excluding leucine, methionine, tyrosine
Damage to the intestinal epithelium reduces nutrient absorption and animal growth, and can have negative long-term health effects on livestock. Because the intestinotropic hormone glucagon-like peptide 2 (GLP-2) has been shown to contribute to gut integrity, reduce inflammation, and improve nutrient
Gametocyte proteins of Eimeria spp. are essential components of the oocyst wall, and some of these proteins have been analysed to identify targets of transmission-blocking vaccines against avian coccidiosis. In the present study, a cDNA from E. necatrix gametocytes was cloned and sequenced. The cDNA
Infections with internal parasites are one of the most important causes of reduced productivity in first-grazing season cattle (FGSC). In conventional herds, nematode infections can be controlled by prophylactic anthelmintic treatments, but this is prohibited in organic production. The purpose of
Twenty-four calves unexposed to pasture were allocated to four groups and inoculated with either two doses of 5 million Eimeria alabamensis oocysts at turn-out (E), 90,000 L3 of Ostertagia ostertagi and Cooperia oncophora divided on six occasions (N) or both oocysts and larvae as above (E + N). A
