Bartonella quintana


Also found in: Encyclopedia, Wikipedia.

Bartonella quintana

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 quintana

A 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.
 
Diagnosis
Culture, direct immunofluorescence, DNA-hybridisation, PCR-amplified RFLPs, serology.
 
Management
Empirical—nafcillin, ceftriaxone, etc.

Bar·to·nel·la quin·ta·na

(bahr-tō-nel'ă kwin-tan'ă)
A bacterial species closely resembling Rickettsia in staining properties, morphology, and mode of transmission between hosts. Organisms usually reside extracellularly in arthropod hosts and intracellularly in mammalian hosts. Type species of the genus Bartonella.

Many commercially available antibody tests focus primarily on Bartonella henselae and Bartonella quintana, a small subset of the Bartonella species that can cause human disease.
So too are the genomes of the bacterial pathogens that the body louse transmits to its human hosts: Rickettsia prowazekii (which causes epidemic typhus), Borrelia recurrentis (the agent of relapsing fever) and Bartonella quintana (which causes trench fever).
IgG cross-reactivity can occur between B henselae and Bartonella quintana because these tests use whole bacteria or bacterial lysates as an antigen.
