Answer

The extracellular pathogen B quintana causes trench fever. Although rarely fatal, this disease has been the cause of many epidemics and is believed to be related to bacterial infective endocarditis. Infection in humans results from autoinoculation of louse feces into abraded or scratched skin. The infection has a 10- to 30-day latency period and results in a fever similar to that of typhus, with headache, myalgia, and pain in the back and the legs.
