复发热是由复发热螺旋体经虫媒传播引起的急性传染病,复发热螺旋体属于疏螺旋体属,又名包柔螺旋体属,按其传播媒介分虱传与蜱传两类,蜱的分布有严格的地区性,故其所致的复发热亦有严格的地区性。1995年,Fukunaga等发现了一种新型的复发热螺旋体,由硬蜱属全沟硬蜱传播,将其命名为宫本疏螺旋体。这一发现扩大了人类对地理范围内复发热螺旋体感染人类的认知。本文就宫本疏螺旋体的基本情况做一简要概述。
Relapsing fever is an acute insect-- borne disease caused by infection with certain spirochetes in the genus Borrelia. Depending on the vector, relapsing fever can be divided into two types: tick--borne relapsing fever and louse-- borne relapsing fever. Tick--born relapsing fever has rigid regional characteristics. Borrelia miyamotoi, a spirochete in the genus Borrelia that is transmitted by ticks in the genus Ixodes, was first identified by Fukunaga in 1995. This discov- ery increased human knowledge regarding the geographic range of the Borrelia spirochetes that cause relapsing fever in hu- mans. This article briefly summarizes Borrelia miyamotoi was made.
