Serological evidence of exposure to Rickettsia felis and Rickettsia typhi in Australian veterinarians [PDF]

, 2013
BACKGROUND: Rickettsia felis and Rickettsia typhi are emerging arthropod-borne zoonoses causing fever and flu-like symptoms. Seroprevalence and risk factors associated with exposure to these organisms was explored in Australian veterinarians.

Genetic Classification of “Rickettsia heilongjiangii” and “Rickettsia hulinii,” Two Chinese Spotted Fever Group Rickettsiae [PDF]

Journal of Clinical Microbiology, 2000
To determine the phylogenetic position of two new rickettsial strains isolated from ticks in China, 16S ribosomal DNA,gltA, and ompA (apart from the tandem repeat units) genes were amplified by PCR and sequenced. The phylogenetic relationships between these strains and other rickettsiae were inferred from the comparison of sequences of the three genes ...

Note: Rickettsia slovaca sp. nov., a member of the spotted fever group rickettsiae [PDF]

International Journal of Systematic Bacteriology, 1998
The name Rickettsia slovaca sp. nov. (type strain is strain B) is proposed for a member of the spotted fever group (SFG) rickettsiae which was isolated from Dermacentor marginatus ticks in Slovakia in 1968, and was recently implicated in human febrile illness.
