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。 Relapses is an acute infectious disease caused by the transmission of relapsing fever spirochaetes through the zoospore. The recurrent fever spirochaetes belong to the genus Borrelia, also known as the genus Borrelia, and are classified according to their vectors as ticks and ticks Of the regional, so the resulting relapse fever also has a strict regional. In 1995, Fukunaga et al. Found a new type of recurrent fever spirochaetes, which was transmitted by Ixodes iridiformis and named it as Borrelia mirabilis. This finding expands the human perception of humans in the geographic area of ​​Reykospirillum spirochete. In this paper, a brief overview of the basic situation of Borrelia.
