Rickettsia felis, an emerging flea-transmitted human pathogen
Rickettsia felis was first recognised two decades ago and has now been described as endemic to all continents except Antarctica. The rickettsiosis caused by R. felis is known as flea-borne spotted fever or cat-flea typhus. The large number of arthropod species found to harbour R. felis and that may act as potential vectors support the view that it is a pan-global microbe. The main arthropod res...
متن کاملRickettsia felis, an Emerging Flea-Borne Rickettsiosis
Rickettsia felis is an emerging insect-borne rickettsial pathogen and the causative agent of flea-borne spotted fever. First described as a human pathogen from the USA in 1991, R. felis is now identified throughout the world and considered a common cause of fever in Africa. The cosmopolitan distribution of this pathogen is credited to the equally widespread occurrence of cat fleas (Ctenocephali...

Rickettsia heilongjiangensis is an emerging tick-transmitted human pathogen causing far-Eastern spotted fever. Here we report the complete sequence and the main features of the genome of R. heilongjiangensis (strain 054).
متن کاملRickettsia felis: A Review of Transmission Mechanisms of an Emerging Pathogen
Rickettsia felis is an emerging pathogen of the transitional group of Rickettsia species and an important cause of febrile illness in Africa. Since the organism’s original discovery in the early 1990s, much research has been directed towards elucidating transmission mechanisms within the primary host and reservoir, the cat flea (Ctenocephalides felis). Several mechanisms for vertical and horizo...
متن کاملVertical transmission of Rickettsia felis in the cat flea (Ctenocephalides felis Bouché).
Rickettsia felis can be maintained in cat fleas by vertical transmission for up to 12 generations without the benefit of an infected host. Horizontal transmission or the acquisition of R. felis by fleas feeding on cats or artificially infected meals were not demonstrated in this study. Horizontal transmission of R. felis by the ingestion of feces or eggs by flea larvae was not detected. We also...
