Abstract

1974年から2009年までに,富山県衛生研究所あるいは富山医科薬科大学医学部感染予防医学教室へ同定が依頼された富山県内のマダニ人体刺症40例について報告し,既報と合わせて本県におけるマダニ人体刺症の概要を記述した.今回報告した刺症の原因種は,キチマダニ(1例),ヤマトチマダニ(2例),フタトゲチマダニ(3例),チマダニ属の未同定種(2例),カモシカマダニ(4例),ヒトツトゲマダニ(3例),タネガタマダニ(6例),ヤマトマダニ(11例),シュルツェマダニ(6例),マダニ科の未同定種(2例)であった.10例(ヤマトマダニ3例,タネガタマダニ1例,シュルツェマダニ3例,ヒトツトゲマダニ2例,マダニ科の未同定種1例)についてB.burgdorferiの抗体検査を実施したが,結果はすべて陰性であった.マダニ刺症の病理組織学的検査を実施した6例中の4例(ヤマトマダニ2例,タネガタマダニ1例,マダニ科の未同定種1例)にセメント物質とムチン沈着が確認された.これまでに報告された富山県のマダニ刺症は1,2,11月を除いたすべての月で発生しており,特に5〜6月に多かった.患者の年齢は2〜88歳であった.マダニの寄生部位は,頚部がもっとも多く,耳介,胸部,腹部と続いた.患者がマダニの寄生を受けた場所の大部分は山林であった.

Forty cases of human infestations with hard ticks (Acari: Ixodidae) were reported in Toyama Prefecture, Honshu, Japan from 1974 to 2009. Causative tick species were Haemaphysalis flava (1 case), H. japonica (2 cases), H. longicornis (3 cases), Haemaphysalis sp. (2 cases), Ixodes acutitarsus (4 cases), I. monospinosus (3 cases), I. nipponensis (6 cases), I. ovatus (11 cases), I. persulcatus (6 cases) and Ixodidae gen. sp. (2 cases). Although serological examination was carried out for antibodies against the borrelial antigen Borrelia burgdorferi in the following 10 cases, the antibody was not detected in 3 of the I. ovatus cases, 1 of I. nipponensis, 3 of I. persulcatus, 2 of I. monospinosus and 1 of Ixodidae gen. sp. A cement-like substance and mucinosis were observed in four cases: 2 of I. ovatus, 1 of I. nipponensis and 1 of Ixodidae gen. sp. by histopathological examination of the infestation sites. This paper reviews the infestations with ticks occurring in Toyama Prefecture between 1973 and 2009. The reported cases occurred during the period from March to December except for November, with the highest incidences in May and June. The ages of the patients ranged from 2 to 88 years. The most common infestation site was the neck of the patients. The majority of the tick infestations were principally acquired in mountainous areas.
