Leptospira Species in the Environment

Introduction

Figure 1. Dark field (a) and shadowed electron (b) photomicrographs of Leptospira spp.

Figure 2.The outer membrane (Om), inner membrane (IM), peptidoglycan layer (PG), and periplasmic flagellum (PF) in a 3-D reconstruction of intact L. interrogans (A) and L. biflexa (B).Zoom-in views reveal the detail of the cell envelope of L. interrogans (C) and L. biflexa (D). Panels E and F show the density profiles of L. interrogans and L. biflexa, respectively.

Figure 3.Molecular architecture of the intact flagellar motor of Leptospira spp.(A) Centered section parallel to the direction of the filament of an assymetric reconstruction of the Leptospiral motors. Panels B, C, D and E are horizontal cross sections.The locations of the sections are indicated in panel A. Panel B shows a section that lies inside the socket formed by the collar in periplasmic space. Section C transects the cytoplasmic side of the MS ring, just above the C ring. Sections D and E are located on the top and bottom of the C ring, respectively. Surface rendering of the Leptospira flagellar motor is presented in panels F and G.

Figure 4. Two types of spherical bodies in Leptospira spp. High and low density spherical bodies were labeled with dark and white arrows, respectively. (A) Cryo-ET tomogram slice of an L. biflexa cell, with spherical bodies (`100nm) located in the cell center. (B) Cryo-ET of an L. interrogancs cell shows that the spherical bodies are randomly positioned along the cell body, with a diameter of `30 nm. (C) High-magnificatoin view of a spherical body showing the absence of a phospholipid bilayer.
