candidatus 'rickettsia senegalensis' in cat fleas in senegal.	epidemiological studies of rickettsia felis and related bacteria are very important, because the natural cycle of this important infection has not yet been established. the recent emergence of r. felis-associated febrile diseases in west and east africa demands insightful epidemiological studies of the vectors and reservoirs of this bacterium in africa. twenty-nine cat fleas, ctenocephalides felis, were tested for the presence of rickettsiae, including r. felis, bartonellae, and borreliae, with ...	2014	25755888
detection of rickettsia species in fleas collected from cats in regions endemic and nonendemic for flea-borne rickettsioses in california.	rickettsia typhi, transmitted by rat fleas, causes most human flea-borne rickettsioses worldwide. another rickettsia, rickettsia felis, found in cat fleas, ctenocephalides felis, has also been implicated as a potential human pathogen. in the continental united states, human cases of flea-borne rickettsioses are reported primarily from the southern regions of texas and california where the cat flea is considered the principal vector. in california, more than 90% of locally acquired human cases ar ...	2016	26824189
opossums and cat fleas: new insights in the ecology of murine typhus in galveston, texas.	murine typhus is an acute undifferentiated febrile illness caused by rickettsia typhi the classic reservoir (rattus spp.) and flea vector (xenopsylla cheopis) were once culprits of murine typhus in the united states. vector and rodent control efforts have drastically decreased the prevalence of disease, except in a few endemic foci where opossums and cat fleas play a role in transmission. since 2012, there has been a reemergence of murine typhus in galveston, tx. we hypothesize that opossums and ...	2016	27273642
seroepidemiology of rickettsial infections in northeast india.	resurgence of scrub typhus was reported in northeast india in 2010 after a gap of 67 years since world war ii. however, the presence of other rickettsial infections remained unknown from this region. a seroepidemiological investigation was undertaken in the scrub typhus affected areas from 2013-2015 in assam, arunachal pradesh and nagaland to assess the exposure to other rickettsial diseases besides scrub typhus.	2016	27618917
