Question

Quizplus · Accepted Answer

The rat flea, Xenopsylla cheopis, is the vector for Rickettsia typhi. Humans become infected when an infected flea bites the host and defecates near the bite site; bacteria may be rubbed into the wound when the host scratches the bite. Animals may ingest whole fleas while grooming themselves, thus ingesting the bacteria as well.
