Rickettsia felis rickettsiosis in Yucatán

The Lancet, 2000
Summary Three patients with fever, exanthem, headache, and central-nervous-system involvement were diagnosed with Rickettsia felis infection by specific PCR of blood or skin and seroconversion to surrogate Rickettsia antigens. Although R felis's relationship to other Rickettsia species is known and the pathogenic potential of this clade is ...

POLYGENIC DETECTION OF RICKETTSIA FELIS IN CAT FLEAS (CTENOCEPHALIDES FELIS) FROM ISRAEL

The American Journal of Tropical Medicine and Hygiene, 2006
The presence of Rickettsia felis, an emerging bacterial pathogen, was investigated in 79 cat flea (Cteno-cephalides felis) pools from Israel (5 to 20 fleas each) by polymerase chain reaction (PCR) and sequencing of 5 different genes. Amplified targets included both metabolic (gltA and fusA) and surface antigen (ompA, ompB, and the 17-kDa antigen) genes.

Rickettsia felis, from Culture to Genome Sequencing

Annals of the New York Academy of Sciences, 2005
Abstract: Rickettsia felis has been recently cultured in XTC2 cells. This allows production of enough bacteria to create a genomic bank and to sequence it. The chromosome of R. felis is longer than that of previously sequenced rickettsiae and it possess 2 plasmids.

Rickettsia felisin Cat Fleas in Taiwan

Vector-Borne and Zoonotic Diseases, 2009
We describe the first detection of Rickettsia felis in cat fleas (Ctenocephalides felis) in Taiwan. Natural infections of R. felis in cat fleas were isolated and confirmed using polymerase chain reaction (PCR) and an immunofluorescence assay. The infection rate in individual fleas and the minimum infection rate in pooled fleas detected by the PCR ...

Horizontal transmission of Rickettsia felis between cat fleas, Ctenocephalides felis.

Molecular ecology, 2012
Rickettsia felis is a rickettsial pathogen primarily associated with the cat flea, Ctenocephalides felis. Although laboratory studies have confirmed that R. felis is maintained by transstadial and transovarial transmission in C. felis, distinct mechanisms of horizontal transmission of R. felis among cat fleas are undefined.
