ABSTRACT
Parasitic infections can have detrimental effects on the reproductive capacity of their hosts. Infections by the cestode Taenia pisiformis in rabbits is generally not associated with increased mortality of offspring or with loss of maternal body condition but can result in reduced fecundity, and increased circulating progesterone levels have been reported in infected does compared to uninfected ones. In the present study, the possibility that T. pisiformis infection affects fecundity by reducing embryonic implantation was examined. Seven anesthetized New Zealand does were orally infected with 1000 eggs of T. pisiformis, and seven were administered saline. Seven weeks after infection, does were mated, and 7 days after, humanely sacrificed. A decrease in the number of implanted embryos and a decrease in the size of the embryo vesicles in infected does were observed (P ≤ 0.02, Student's t-test). There was a negative correlation between the number of hepatic granulomas and embryo implantation (ρ = - 0.8, P = 0.04, Spearman's test).
