seasonal fluctuations of small mammal and flea communities in a ugandan plague focus: evidence to implicate arvicanthis niloticus and crocidura spp. as key hosts in yersinia pestis transmission.the distribution of human plague risk is strongly associated with rainfall in the tropical plague foci of east africa, but little is known about how the plague bacterium is maintained during periods between outbreaks or whether environmental drivers trigger these outbreaks. we collected small mammals and fleas over a two year period in the west nile region of uganda to examine how the ecological community varies seasonally in a region with areas of both high and low risk of human plague cases.201525573253
early-phase transmission of yersinia pestis by cat fleas (ctenocephalides felis) and their potential role as vectors in a plague-endemic region of recent decades, the majority of human plague cases (caused by yersinia pestis) have been reported from africa. in northwest uganda, which has had recent plague outbreaks, cat fleas (ctenocephalides felis) have been reported as the most common fleas in the home environment, which is suspected to be a major exposure site for human plague in this country. in the past, c. felis has been viewed as only a nuisance-biting insect because limited laboratory studies suggested it is incapable of transmi ...200818541775
