摘要: 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 in the United States. Vector rodent control efforts have drastically decreased prevalence disease, except a few endemic foci where opossums cat fleas play role transmission. Since 2012, there has been reemergence Galveston, TX. We hypothesize that are involved transmission R. Galveston. To explore this, we sought to find seroprevalence group antibodies from opossums. also parasitizing these animals. collected blood 12 found eight (66.7%) had presence anti-R. antibodies. All infested with fleas; total 250 Ctenocephalides felis Seven (53.8%) molecular evidence infection, while six (46.2%) contained Candidatus senegalensis, organism closely related minimum infection rate for was 7.0%. senegalensis 6.1%. Our study demonstrates infected parasitize It therefore likely their city's recent typhus.
