Trace Element Nutriture of the Chick as Affected by Eimeria Acervulina Infection
… 2 x 10('5), 4 x 10('5) or 8 x 10('5) sporulated Eimeria acervulina oocysts on days 0, 3, 6, 9 and 12 of the 13- or 14-day assay periods.

Studies on cathepsin B of Eimeria tenella and pyroglutamyl peptidase of Leishmania major
… involved in the oocyst wall formation in Eimeria. These data suggest that the cathepsin B may play roles in both cell invasion by sporozoites and the formation of the protective wall of the oocyst. A single copy gene encoding a PPI was identified in the genome database of L. major. Active …

Expression of Digestive Enzymes and Nutrient Transporters in the Intestine of Eimeria-challenged Chickens
… coccidiosis is caused by the intestinal protozoa Eimeria. The parasite"s site of infection in the intestine is site specific. Eimeria acervulina infects the duodenum, E. maxima the jejunum, and E. tenella the ceca. Lesions in the intestinal mucosa cause reduced feed efficiency and body weight gain …

Pathological Changes and Immunity Associated With Experimental Eimeria Vermiformis Infections in the Mouse (Mus Musculus)
Pathological changes and immunity were studied in outbred Swiss mice inoculated with 5,000, 10,000, 20,000 or 40,000 oocysts. Oocyst output, food and water consumption, urine production and weight changes were observed daily for 25 days after inoculation (DAI). Histopathologic changes were studied …

Trace Element Interrelationships and Zinc Status of the Chicken as Affected by Eimeria Acervulina Infection
… interactions in young chicks infected with Eimeria acervulina (duodenal coccidiosis). The mineral interactions explored were lead-zinc, lead-copper, calcium-zinc-phytate, cadmium-zinc and iron-zinc. Experimental coccidial infections were produced by crop inoculation of 4 x 10('5) sporulated …

Development of a Turkey Coccidiosis Vaccine Candidate: an Attenuated Line of the Protozoan Parasite, Eimeria meleagrimitis
… by protozoan parasites belonging to the genus Eimeria. Drugs are most commonly used to control coccidiosis. Widespread usage of anticoccidial drugs in the field has resulted in development of drug resistant strains and consequently decreased drug efficacy. An alternative control strategy using …

Temporal variation in infection of male sardine (Sardinops sagax) by a coccidian testicular parasite (Eimeria sardinae)
… sagax) by a testicular coccidian parasite Eimeria sardinae was examined between putative western and southern stocks of this fish species. Samples were collected by commercial vessels from five localities; Gansbaai, St Helena Bay, Mosselbay, Port Alfred and Port Elizabeth (west and south …

Intestinal Mucosal Mast Cell Immune Response and Pathogenesis of Two Eimeria Acervulina Isolates in Broiler Chickens
… intestinal immune responses to two isolates of Eimeria acervulina (EA), EA1 and EA2. In three experiments, broiler chicks were divided into control (non-challenged), EA1, or EA2 challenged (14 days of age) groups. On day 6 post-challenge (PC), changes in body weight were determined, intestinal …
