Review
Cat-scratch disease is a common infection that usually presents as tender lymphadenopathy. It should be included in the differential diagnosis of fever of unknown origin and any lymphadenopathy syndrome. Asymptomatic, bacteremic cats with Bartonella henselae in their saliva serve as vectors by biting and clawing the skin. Cat fleas are responsible for horizontal transmission of the disease from cat to cat, and on occasion, arthropod vectors (fleas or ticks) may transmit the disease to humans. Cat-scratch disease is commonly diagnosed in children, but adults can present with it as well. The causative microorganism, B. henselae, is difficult to culture. Diagnosis is most often arrived at by obtaining a history of exposure to cats and a serologic test with high titers (greater than 1:256) of immunoglobulin G antibody to B. henselae. Most cases of cat-scratch disease are self-limited and do not require antibiotic treatment. If an antibiotic is chosen, azithromycin has been shown in one small study to speed recovery. Infrequently, cat-scratch disease may present in a more disseminated form with hepatosplenomegaly or meningoencephalitis, or with bacillary angiomatosis in patients with AIDS.

Review
Bartonellosis are diseases caused by any kind of Bartonella species. The infection manifests as asymptomatic bacteremia to potentially fatal disorders. Many species are pathogenic to humans, but three are responsible for most clinical symptoms: Bartonella bacilliformis, Bartonella quintana, and Bartonella henselae. Peruvian wart, caused by B. bacilliformis, may be indistinguishable from bacillary angiomatosis caused by the other two species. Other cutaneous manifestations include maculo-papular rash in trench fever, papules or nodules in cat scratch disease, and vasculitis (often associated with endocarditis). In addition, febrile morbilliform rash, purpura, urticaria, erythema nodosum, erythema multiforme, erythema marginatus, granuloma annularis, leukocytoclastic vasculitis, granulomatous reactions, and angioproliferative reactions may occur. Considering the broad spectrum of infection and the potential complications associated with Bartonella spp., the infection should be considered by physicians more frequently among the differential diagnoses of idiopathic conditions. Health professionals and researchers often neglected this diseases.

Bacillary angiomatosis is an unusual infectious disease, with angioproliferative lesions, typical of immunocompromised patients. It is caused by Bartonella quintana and Bartonella henselae, two infectious agents of the genus Bartonella, which trigger variable clinical manifestations, including cutaneous vascular and purpuric lesions, and regional lymphadenopathy, and even a systemic disease with visceral involvement. We report a 38-year-old HIV positive male presenting with a history of six months of cutaneous growing purple angiomatous lesions, located also in nasal fossae, rhi-nopharynx and larynx. The skin biopsy was compatible with bacillary angiomatosis. Polymerase chain reaction of a tissue sample showed homology with B. quintana strain Toulouse. The patient was treated with azithromycin and ciprofloxacin with a favorable evolution.

Review
Cat-scratch disease (CSD) was first described by Debré in 1950, yet the causative bacterial agent of CSD remained obscure until 1992, when Bartonella (formerly Rochalimaea) henselae was implicated in CSD by serological and microbiologic studies. Bartonella henselae had initially been linked to bacillary angiomatosis (BA), a vascular proliferative disease most commonly associated with long-standing human immunodeficiency virus infection or other significant immunosuppression. Bartonella henselae has also been associated with bacillary peliosis, relapsing bacteraemia and endocarditis in humans. Cats are healthy carriers of B. henselae, and can be bacteraemic for months or years. Cat-to-cat transmission of the organism by the cat flea, with no direct contact transmission, has been demonstrated. Two new Bartonella species have been identified in the cat reservoir, namely: B. clarridgeiae and B. koehlerae. The role of these species in the aetiology of CSD still needs to be confirmed by isolation or DNA identification from lesions in humans. The author discusses the present state of knowledge on the aetiology, clinical features and epidemiological characteristics of CSD/BA, in addition to diagnosis, treatment and prevention.

The author discusses the present state of knowledge on the aetiology, clinical features and epidemiological characteristics of cat-scratch disease and bacillary angiomatosis.
