Lack of cross-protection between Cowdria ruminantium and Ehrlichia phagocytophila.
Antigenically distinct stocks of Cowdria ruminatium from Senegal and South Africa were compared with a Dutch isolate of Ehrlichia phagocytophila in cross-immunity trials in goats. There was a complete absence of cross-immunity between E. phagocytophila and C. ruminantium, despite previous observations that both rickettsial organisms have certain antigenic determinants in common.
