The extracellular pathogen B quintana causes trench fever and infective endocarditis. Although rarely fatal, this disease has been the cause of many epidemics, including trench fever during World War I. [30] 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.
