Bartonella

 [bahr″to-nel´ah]
a genus of bacteria of the family Bartonellaceae, made up of gram-negative cells in chains; it includes B. bacillifor´mis, the etiologic agent of bartonellosis (carrión's disease), and B. hen´selae, the etiologic agent of cat-scratch disease.

Bartonella

(bar'tō-nel'ă),
A genus of bacteria found in humans and in arthropod vectors; grows slowly in artificial media and may be recovered from blood cultures from infected patients; may be seen intracellularly in tissues and erythrocytes. Bartonella is a minute, gram-negative, coccobacillary organism, which may appear curved; it can cause an indolent, poorly defined, progressive disease in immunocompromised patients, including those with HIV infections.

Bartonella

[bär′tənel′ə]
Etymology: Alberto Barton, Peruvian bacteriologist, 1871-1950
a genus of small gram-negative flagellated pleomorphic coccobacilli, some of which are opportunistic pathogens. Members of the genus infect red blood cells and the epithelial cells of the lymph nodes, liver, and spleen. They are transmitted at night by the bite of a sandfly of the genus Phlebotomus. Three species are considered important in human disease. B. bacilliformis causes bartonellosis. Because of its distinctive appearance, it is easily identified on microscopic examination of a smear of blood stained with Wright's stain. B. henselae is the causative agent of cat-scratch fever and bacillary angiomatosis. B. quintana causes trench fever and may cause peliosis of the liver.

Bar·to·nel·la

(bahr-tō-nel'ă)
A genus of bacteria 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.

Bartonella

a genus of gram-negative, coccoid or rod-shaped bacteria in the family Bartonellaceae. B. bacilliformis is the cause of Oroya fever or Carrión's disease in humans and occasionally dogs, in South America.

Bartonella henselae
causes cat-scratch disease, bacillary angiomatosis, and endocarditis in humans.
