Human toxicosis caused by the tick Ixodes redikorzevi in Israel.

Abstract

The clinical symptoms of a tick toxicosis caused by Ixodes redikorzevi in northern Israel are described. The patient was a nine-year-old Arab boy from an agricultural village who was admitted to a local hospital and had been suffering for 4 days from fever and torticollis. A partially engorged female tick was removed from the nuchal area of the scalp, and the symptoms disappeared within 2 hours. Morphometrical measurements indicated that the tick was attached to the skin for 3-4 days.
