| bartonella | A genus of gram-negative bacteria characteristically appearing in chains of several segmenting organisms. It occurs in man and arthropod vectors and is found only in the andes region of south america. This genus is the aetiologic agent of human bartonellosis. The genus rochalimaea, once considered a separate genus, has recently been combined with the genus bartonella as a result of high levels of relatedness in 16s rrna sequence data and DNA hybridization data.

| Bartonella anaemia | Anaemia occurring in infection with Bartonella bacilliformis and characterised by an acute febrile anaemia of rapid onset and high mortality. Occurs in central Andean mountains of northern South America; vector is phlebotomine sandfly, Lutzomyia. (05 Mar 2000) |
| Bartonella bacilliformis | A species found in the blood and epithelial cells of lymph nodes, spleen, and liver in Oroya fever (it is the cause of Oroya fever) and in blood and eruptive elements in verruga peruana; probably also found in sandflies (Phlebotomus verrucarum); known to be established only on the South American continent and perhaps in Central America; it is the type species of the genus Bartonella.

| bartonella henselae | A species of gram-negative bacteria that is the aetiologic agent of bacillary angiomatosis (angiomatosis, bacillary). This organism can also be a cause of cat scratch disease in immunocompetent patients. (12 Dec 1998) |
| bartonella infections | Infections by the genus bartonella. Bartonella bacilliformis can cause acute febrile anaemia, designated oroya fever, and a benign skin eruption, called verruga peruana. Bartonella quintana causes trench fever, while bartonella henselae is the aetiologic agent of bacillary angiomatosis (angiomatosis, bacillary) and is also one of the causes of cat scratch disease in immunocompetent patients.

| bartonella quintana | A species of gram-negative bacteria in which man is the primary host and the human body louse, pediculus humanus, the principal vector. It is the aetiological agent of trench fever. (12 Dec 1998) |
| bartonellaceae | A family of small gram-negative bacteria whose organisms are parasites of erythrocytes in man and other vertebrates and the aetiologic agents of several diseases. (12 Dec 1998) |
