The experimental transmission of Babesia divergens by Ixodes ricinus

Abstract

A strain of Babesia divergens, previously maintained by needle passage in splenectomized calves, has been transmitted in the laboratory by larvae and on one occasion by nymphs of Ixodes ricinus. The infection appeared to be transmitted most readily by larvae after infection of the previous adult stage. The techniques described could be used to maintain B. divergens in splenectomized calves by cyclical transmission through I. ricinus. © 1963.
