Bartonella quintana has repeatedly emerged throughout history as a cause of infection among distinct and diverse populations across the globe. The bacterium has been identified as the agent in trench fever, a disease responsible for one million deaths during World War 1. A disease of the past, B. quintana has re-emerged as a public health concern after recent outbreaks have infected inner-city homeless people and patients suffering from AIDS. Despite these characteristics, little is known about the pathogen. The gram- negative cell wall associated with the bacterium consists of a multi-layered structure that contains proteins essential to the structure and function of the bacterium. A prominent outer membrane protein has been identified to contribute to cell survival.
A defining characteristic of Bartonella quintana is its Gram-negative rod morphology. The Gram-negative cell wall is a multi-layered structure that contains proteins essential to the structure and function of the bacterium. Proteins function as both structural and catalytic components essential to the processes of the cell. A recent study identified a prominent surface binding protein of about 36 kiladaltons.
