Variations of Plasmid Content in Rickettsia felis

PLoS ONE, 2008
Since its first detection, characterization of R. felis has been a matter of debate, mostly due to the contamination of an initial R. felis culture by R. typhi. However, the first stable culture of R. felis allowed its precise phenotypic and genotypic characterization, and demonstrated that this species belonged to the spotted fever group rickettsiae ...

Evidence for a specific host-endosymbiont relationship between ‘Rickettsia sp. genotype RF2125’ and Ctenocephalides felis orientis infesting dogs in India

Parasites & Vectors, 2015
Background Fleas of the genus Ctenocephalides serve as vectors for a number of rickettsial zoonoses, including Rickettsia felis. There are currently no published reports of the presence and distribution of R.

Dissemination of bloodmeal acquired Rickettsia felis in cat fleas, Ctenocephalides felis [PDF]

Parasites & Vectors, 2013
Cat fleas, Ctenocephalides felis, are known biological vectors for Rickettsia felis. Rickettsial transmission can be vertical via transovarial transmission within a flea population, as well as horizontal between fleas through a bloodmeal. The previously undescribed infection kinetics of bloodmeal-acquired R. felis in cat fleas provides insight into the

Rickettsia felisin the United Kingdom

Emerging Infectious Diseases, 2003
To the Editor: Rickettsia felis is a bacterium transmitted by the cat flea (Ctenocephalides felis), which also acts as a reservoir by means of transovarial transmission (1–3). The distribution of R. felis is potentially as wide as that of its insect host, and to date, its presence has been confirmed in cat flea populations in North and South America ...
