Seaports and other rat-infested areas are also common habitats for X. cheopis. Fleas are nidiculous parasites; they live in the host's nest. Clothing, beds and couches make perfect homes for many of these fleas. Fleas only attach to the host while they are sucking blood; at other times they are free-living in the host's nest.

5 Μαΐ 2022 · The rat flea, Xenopsylla cheopis, is the primary vector of the bubonic plague bacterium, Yersinia pestis, and also serves as a vector of bacteria belonging to the genera Rickettsia and Bartonella. As a parasite of the commensal rat, Rattus ssp., it aligns with anthropogenic environments (i.e., sewer systems, human habitation, crop fields, etc.).
Transmission by fleabite is a relatively recent evolutionary adaptation of Yersinia pestis, the bacterial agent of bubonic plague. To produce a transmissible infection, Y. pestis grows as an attached biofilm in the foregut of the flea vector. ...
The oriental rat flea can also vector the bacterium Rickettsia typhi, which can cause the disease murine (flea-borne) typhus in humans. Rats and mice, as well as many other rodents, may serve as reservoirs of Rickettsia typhi. Humans can become infected when exposed to the rodents or to infected fleas (Figure 5).
