Abstract

Spirochetes have flagella within the cell body and swim by wriggling the spiral cell body. Besides they have been known to be critical agents causing various infectious diseases, their eccentric appearances and motilities have been attracting many scientists in a wide variety of fields other than bacteriologists. Unlike externally flagellated bacteria that swim by using flagella as a screw propeller, spirochetes progress in a liquid by changing their cell shapes. To understand the unique motion mechanism of spirochetes, many experiments and theoretical studies are being carried out. In this review, I will summarize morphological and motile properties of various species of spirochete, such as Borrelia, Treponema and Brachyspira. I will also expound on the motion mechanism of Leptospira with our latest results obtained by high-resolution optical photometry.

[螺旋体的形态和运动]。
螺旋体在细胞体内有鞭毛,通过扭动螺旋状细胞体游动。除了已知它们是引起各种传染病的关键因素外,它们古怪的外观和运动已经吸引了除细菌学家以外的许多其他领域的科学家。与利用鞭毛作为螺旋桨游动的外部鞭毛细菌不同,螺旋体通过改变细胞形状在液体中前进。为了了解螺旋体独特的运动机制,人们进行了大量的实验和理论研究。本文综述了疏螺旋体、密螺旋体和短螺旋体等不同种类螺旋体的形态和运动特性。我还将用高分辨率光学光度法获得的最新结果来阐述钩端螺旋体的运动机制。
