Ixodid tick attacks on man in Israel: medical implications.

Various species of ixodid ticks that have been recorded to attack man were surveyed, and boutonneuse fever caused by Rickettsia conorii, which is transmitted in Israel by Rhipicephalus sanguineus s.l., is reviewed. Only in one case were a complement fixation test and exact determination of the species of the tick performed. Tick toxicosis and tick paralysis are discussed, and the possibility of human babesiosis and Lyme disease or erythema chronicum migrans appearing in Israel is considered.
