The cat flea, , is an inefficient vector of the plague bacterium () and is the predominant off-host flea species in human habitations in the West Nile region, an established plague focus in northwest Uganda. To determine if might serve as a bridging vector in the West Nile region, we collected on- and off-host fleas from human habitations and used a real-time polymerase chain reaction-based assay to estimate the proportion of off-host that had fed on humans and the proportion that had fed on potentially infectious rodents or shrews. Our findings indicate that cat fleas in human habitations in the West Nile region feed primarily on domesticated species. We conclude that is unlikely to serve as a bridging vector in this region.
