Incidence of Brown Dog Ticks, Rhipicephalus sanguineus, at a Kennel in Okayama Prefecture

Abstract

Twenty two adult dogs suffered from tick infestation at a kennel in Okayama Prefecture in the summer of 1994. Four of them had been introduced from U.S.A. Some dogs showed pyoderma, anemia, neutrophilia or eosinophilia. Neither Babesia gibsoni nor Hepatozoon canis was detected on the smear samples of peripheral blood. The ticks detected were morphologically identified as Rhipicephalus sanguineus. This case was a rare incidence of the tick in the other areas of Japan than Okinawa.
