Rickettsia typhi and R. felis in Rat Fleas (Xenopsylla cheopis), Oahu, Hawaii
Rickettsia typhi (prevalence 1.9%) and R. felis (prevalence 24.8%) DNA were detected in rat fleas (Xenopsylla cheopis) collected from mice on Oahu Island, Hawaii. The low prevalence of R. typhi on Oahu suggests that R. felis may be a more common cause of rickettsiosis than R. typhi in Hawaii.
متن کاملRickettsia felis in Xenopsylla cheopis, Java, Indonesia
Rickettsia typhi and R. felis, etiologic agents of murine typhus and fleaborne spotted fever, respectively, were detected in Oriental rat fleas (Xenopsylla cheopis) collected from rodents and shrews in Java, Indonesia. We describe the first evidence of R. felis in Indonesia and naturally occurring R. felis in Oriental rat fleas.
متن کاملEarly-phase transmission of Yersinia pestis by unblocked Xenopsylla cheopis (Siphonaptera: Pulicidae) is as efficient as transmission by blocked fleas.
For almost a century, the oriental rat flea, Xenopsylla cheopis (Rothschild) (Siphonaptera: Pulicidae), was thought to be the most efficient vector of the plague bacterium Yersinia pestis (Yersin). Approximately 2 wk after consuming an infectious bloodmeal, a blockage often forms in the flea's proventriculus, which forces the flea to increase its biting frequency and consequently increases the ...
متن کاملSCIENTIFIC NOTE Fleas Occurring on Mice During the Mouse Population Explosion in the Western Side of Leeward Oahu, Hawaii
A survey of fleas on mice during the mouse population explosion that occurred in eight communities in the western side of leeward Oahu was carried out in the summer of 2006. A total of 1440 mice were obtained. 305 oriental rat fleas, Xenopsylla cheopis (Rothschild) were recovered from these mice. No significant difference existed for the flea infestation rates, the average number of fleas per m...
متن کاملComparative Ability of Oropsylla montana and Xenopsylla cheopis Fleas to Transmit Yersinia pestis by Two Different Mechanisms
BACKGROUND Transmission of Yersinia pestis by flea bite can occur by two mechanisms. After taking a blood meal from a bacteremic mammal, fleas have the potential to transmit the very next time they feed. This early-phase transmission resembles mechanical transmission in some respects, but the mechanism is unknown. Thereafter, transmission occurs after Yersinia pestis forms a biofilm in the prov...
