Experimental Eimeria debliecki infections in nursing and weaned pigs. 1987

D S Lindsay, and B L Blagburn, and T R Boosinger

Three litters of six, 3-day-old nursing pigs were inoculated via a stomach tube with 8.0 X 10(5), 1.6 X 10(6) or 5.0 X 10(6) sporulated oocysts of Eimeria debliecki and four groups of six, 4-week-old weaned pigs were inoculated with 8.0 X 10(5), 1.6 X 10(6), 5.0 X 10(6) or 1.0 X 10(7) sporulated oocysts of E. debliecki to determine its pathogenicity. Clinical coccidiosis or deaths did not result from infections. Infections were confined to the jejunum and occasionally the duodenum. Microscopic lesions of mild to moderate villous atrophy were observed in one nursing pig given 5.0 X 10(6) oocysts and three weaned pigs given 1.6 X 10(6), 5.0 X 10(6) and 1.0 X 10(7) oocysts and examined 5 days post-inoculation. Pathogenic bacteria or viruses were not demonstrated in any pigs. Results of this study indicate that E. debliecki is not a cause of neonatal or weaning diarrhea in pigs.
