Clinical Utility

Bartonella Quintana is a gram negative bacillus transmitted by body louse that can adhere to and invade mammalian cells. It causes Trench Fever which presents with a sudden onset headache, meningitides and relapsing fever. It can also cause Bacillary angiomatosis. The primary diagnostic tool is blood culture. Most at risk for this infection are immunocomprimised patients (HIV in particular), homeless and alcoholics.

Parallel specimens are preferred for IgG antibody testing. Convalescent specimens must be received within 30 days from receipt of the acute specimens.
