Summary

The spectrum of Bartonella infections includes cat scratch disease (CSD), bacillary angiomatosis, trench fever and bartonellosis (or Carrion disease). In immunocompetent individuals, B. henselae infection results in CSD, characterized by self-limited regional lymphadenopathy after a cat scratch or bite distal to the affected node. Histologically, CSD manifests as a granulomatous process. By contrast, B. henselae or B. quintana infection in immunocompromised hosts results in bacillary angiomatosis, comprised of vascular papules and nodules with lobular vascular proliferations of plump endothelial cells on histology. Lesions generally respond well to therapy with erythromycin. Lastly, bartonellosis is caused by B. bacilliformis and transmitted from person to person by sandflies in certain regions of Peru, Colombia and Ecuador. Bartonellosis is characterized by acute and chronic presentations. The acute Oroya fever phase may lead to severe, life-threatening anaemia and requires treatment with chloramphenicol. The chronic verruga peruana phase is associated with less morbidity and responds well to rifampicin (rifampin).
