Studies on ixodid fauna in the northern part of Honshu, Japan : 2. Human cases of tick infestation, especially many cases with a large species Ixodes acutitarsus (Karsh, 1880)

Abstract

This is a report of the human cases of tick infestation which occurred in the northern part of Honshu during the years 1972-1977. These included 18 sporadic cases by hard ticks, a mass case of old rehabilitating patients with Argas japonicus, another mass case with A. vespertilionis at a shrine, and also 67 cases of students with Ixodes acutitarsus who investigated animal habitats in mountains of Shimokita Peninsula. Moreover, it is the first record in Japan that the larvae of I. acutitarsus were collected by flagging method in the same area.
