title: [Cat-scratch disease and other infections caused by Bartonella species].
abstract: Bartonella henselae, the causative agent of cat-scratch disease, was identified recently by DNA amplification techniques. Several other Bartonellae (most of which were called Rochalimaea before) cause disease in humans: B. bacilliformis (Carrion's disease), B. elizabethae (endocarditis) and B. quintana (bacillary angiomatosis and peliosis, chronic bacteraemia and endocarditis, trench fever). B. henselae is transmitted to humans by scratch or bite of a bacteraemic, but asymptomatic, cat, which event may be followed by regional lymphadenitis (classical cat-scratch disease), bacillary angiomatosis or peliosis of liver and spleen (in immune compromised, e.g. HIV-infected individuals) or chronic bacteraemia and endocarditis (in elderly individuals). The incidence in the Netherlands of cat-scratch disease is > 2/100,000/year. If a Bartonella infection is suspected, specific immuno-assays and polymerase chain reaction assay may be applied for diagnosis. Culture of the organism is difficult. Macrolides and tetracyclines have been shown to be effective in treatment of disseminated infections. The natural (self-limiting) course of regional lymphadenitis however is not affected by antibiotic treatment.
