ABSENCE OF PROTECTION AGAINST EIMERIA-NINAKOHLYAKIMOVAE AFTER PRIMO-INFECTION WITH E-OVINOIDALIS IN NEWBORN KIDS

One group of kids (n = 23) was given 2 x 10(5) oocysts of Eimeria ovin oidalis(sheep coccidia) at birth; a second group (n = 23) was kept as an uninoculated control. Body weights, E ninakohlyakimovae oocyst outp ut and serum coccidial antibody levels were monitored up to 77-102 d o f age. No significant difference in any of these parameters was seen b etween the 2 groups, suggesting that no immune response to E ovinoidal is inoculation occurred. These results could be relevant to the absenc e of development of the endogenous stages of E ovinoidalis in kids and /or to the mode of inoculation (moderate and not repeated).
