摘要
江苏省于１９８６年发现有秋冬型恙虫病流行。为查明该病的媒介，作者于１９８６～１９９２年进行了系列调查，结果：根据小盾纤恙螨［Ｌｅｐｔｏｔｒｏｍｂｉｄｉｕｍ（Ｌ）ｓｃｕｔｅｌｌａｒｅ］为恙虫病疫区鼠体的优势螨种；季节消长与居民恙虫病季节分布们一致；能自然感染、叮刺传播和经卵传递恙虫病立克队体［Ｒｉｃｋｅｔｔｓｉａｔｓｕｔｓｕｇａｍｕｓｈｉ，Ｒｔ］；被恙螨叮刺或悬液接种的小白鼠血请中能检测到特异性抗体，血清学分型属Ｇｉｌｌｉａｍ型，以上结果证明小盾纤恋螨为秋冬型恙虫病的传播媒介。
n 1986,
epidemic of tsutsugamushi disease ot au-tumnwinter type was found in Jiangsu province.
Toclarify the vector of this disease, we carried out a senesof studies in 1986～1992.
Leptotronibi`fiunJ (L.)sculellare was found to be a dominant species of chig-ger mite on rats in
the endemic areas and its seasonaldistnbution was correlated with the incidence
oftsutsugamushi disease in inhabitants. This mite couldnaturally be infected by Rickeusia
tsuisugamushi. andR. tsutsugamushi could be transmitted via biting andtransovarial
transmission. Specific antibodies could bedetected in the sera of mice bitten by the mites or
in-oculated with the suspension of mites. Serological typ-ing of the sera of mice was of Gilhain
type. The aboveresults demonstrate that L.(L. ) scutetlare can serve astransmitting vector of
tsutsugamushi disease of au-tumn-winter type.
