formerly the type species of the genus Rochalimaea, this organism causes trench fever and in AIDS patients is associated with septicemia and endocarditis; arthropod vector is Pediculus humanus, the body louse.
Bartonella quintanaA slender, fastidious coccobacillus found in the normal flora of small rodents, which is transmitted by body lice and causes trench fever, bacillary splenitis, bacteraemia, endocarditis and cat-scratch disease, as well as cutaneous bacillary angiomatosis, relapsing fever, and chronic lymphadenopath in alcoholics and in the homeless.
