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 |
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 |
