Proteins of typhus and spotted fever group rickettsiae [PDF]

Infection and Immunity, 1976
Purified radioactive rickettsiae were obtained from irradiated and cycloheximide-inhibited L cells, and their proteins were analyzed by polyacrylamide gel electrophoresis. Rickettsial species could be distinguished by comparing the relative mobilities of constituent proteins after migration of two differentially labeled preparations in a single gel ...

Spotted Fever Group Rickettsiae in Ticks, Morocco

Emerging Infectious Diseases, 2008
A total of 370 ticks, encompassing 7 species from 4 genera, were collected during 2002-2006 from domestic animals and vegetation in the Taza region of northeastern Morocco. Rickettsial DNA was identified in 101 ticks (27%) by sequencing PCR products of fragments of the citrate synthase and outer membrane protein genes of Rickettsia spp.

NOTES: Rickettsia massiliae sp. nov., a New Spotted Fever Group Rickettsia [PDF]

International Journal of Systematic Bacteriology, 1993
We propose the name Rickettsia massiliae sp. nov. (type strain, Mtu1 in the Collection of the World Health Organization Collaborative Center for Rickettsial Reference, Marseille, France) for a spotted fever group rickettsia determined to be distinct from previously recognized species by the serotyping method (L.
