Culture Isolate of Rickettsia felis from a Tick. [PDF]

Int J Environ Res Public Health, 2022
Although the cat flea, Ctenocephalides felis, has been identified as the primary vector of Rickettsia felis, additional flea, tick, mite, and louse species have also been associated with this bacterium by molecular means; however, the role of these arthropods in the transmission of R. felis has not been clarified.

Rickettsia felis in Ctenocephalides felis felis from Five Geographic Regions of Brazil [PDF]

The American Society of Tropical Medicine and Hygiene, 2014
This study evaluated rickettsial infection in 701 Ctenocephalides felis felis fleas that were collected from dogs and cats in 31 municipalities, encompassing all regions and major biomes of Brazil. A total of 268 (38.2%) fleas from 30 municipalities were polymerase chain reaction (PCR) positive for the rickettsial gltA gene.

Rickettsia felis in Ctenocephalides felis from Guatemala and Costa Rica [PDF]

The American Society of Tropical Medicine and Hygiene, 2012
Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis. In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. Ctenocephalides felis were collected directly from dogs and cats, and analyzed by polymerase chain reaction for Rickettsia-specific ...

Rickettsia felisin Fleas, Western Australia [PDF]

Emerging Infectious Diseases, 2006
This study is the first confirmation of Rickettsia felis in Australia. The organism was identified from 4 species of fleas obtained from dogs and cats in Western Australia, by using polymerase chain reaction amplification and DNA sequencing of the citrate synthase and outer membrane protein A genes.
