a new rickettsia species found in fleas collected from human dwellings and from domestic cats and dogs in senegal.	abstract the insects of the order siphonaptera, commonly named fleas, are vectors of pathogens around the world. our previous studies showed that 4.4% of acute febrile diseases in the sine-saloum region of senegal were due to rickettsia felis. the aim of this study was to explain the high prevalence of r. felis infections in two rural senegalese populations by an entomological, systematic monitoring protocol. a total of 232 fleas from three species (ctenocephalides felis, echidnophaga gallinac ...	2012	22214272
molecular detection of rickettsia felis and candidatus rickettsia asemboensis in fleas from human habitats, asembo, kenya.	the flea-borne rickettsioses murine typhus (rickettsia typhi) and flea-borne spotted fever (fbsf) (rickettsia felis) are febrile diseases distributed among humans worldwide. murine typhus has been known to be endemic to kenya since the 1950s, but fbsf was only recently documented in northeastern (2010) and western (2012) kenya. to characterize the potential exposure of humans in kenya to flea-borne rickettsioses, a total of 330 fleas (134 pools) including 5 species (xenopsylla cheopis, ctenoceph ...	2013	23675818
molecular detection of rickettsia felis and bartonella henselae in dog and cat fleas in central oromia, ethiopia.	fleas are important vectors of several rickettsia and bartonella spp. that cause emerging zoonotic diseases worldwide. in this study, 303 fleas collected from domestic dogs and cats in ethiopia and identified morphologically as ctenocephalides felis felis, c. canis, pulex irritans, and echidnophaga gallinacea were tested for rickettsia and bartonella dna by using molecular methods. rickettsia felis was detected in 21% of fleas, primarily c. felis, with a similar prevalence in fleas from dogs and ...	2014	24445204
detection of rickettsia felis, rickettsia typhi, bartonella species and yersinia pestis in fleas (siphonaptera) from africa.	little is known about the presence/absence and prevalence of rickettsia spp, bartonella spp. and yersinia pestis in domestic and urban flea populations in tropical and subtropical african countries.	2014	25299702
high prevalence of rickettsia spp. in dog fleas (siphonaptera: pulicidae) in rural uganda.	fleas are known vectors of zoonotic agents. thirty-five fleas, including 28 ctenocephalides felis (bouché), four pulex irritans (l.), and three echidnophaga gallinacea (westwood) from 19 rural dogs from southwestern uganda were analyzed for the presence of rickettsia spp. (ompb, glta, and 17 kda fragment genes) and bartonella spp. (rpob and its genes) by pcr. rickettsial dna was detected in 27 out of 28 of ct. felis and in two out of four p. irritans. none of the e. gallinacea specimens harbored ...	2017	28399271
