Absence of protection against Eimeria ninakohlyakimovae after primo-infection with E ovinoidalis in new-born kids.
One group of kids (n = 23) was given 2 x 10(5) oocysts of Eimeria ovinoidalis (sheep coccidia) at birth; a second group (n = 23) was kept as an uninoculated control. Body weights, E ninakohlyakimovae oocyst output and serum coccidial antibody levels were monitored up to 77-102 d of age. No significant difference in any of these parameters was seen between the 2 groups, suggesting that no immune response to E ovinoidalis inoculation occurred. These results could be relevant to the absence of development of the endogenous stages of E ovinoidalis in kids and/or to the mode of inoculation (moderate and not repeated).
