Ultrastucture of the surface of Rickettsia prowazeki and Rickettsia akari

E L Palmer et al. Appl Microbiol. 1974 Oct.

Abstract

Negative-contrast electron microscopy revealed that the outer layer of the envelope of rickettsiae is composed of a matrix of tetragonally arranged subunits. The layer projects approximately 7 nm from the cell wall. It is suggested that this outer layer is analogous to the structure considered capsule-like in morphology.
