Bartonella quintana and Bartonella henselae are fastidious gram-negative bacteria responsible for bacillary angiomatosis, trench fever, cat scratch disease, and endocarditis. During a 5-year period, we received 2,043 samples for culture of Bartonella sp. We found Bartonella sp. to be the etiologic agent in 38 cases of endocarditis, 78 cases of cat scratch disease, 16 cases of bacteremia in home...

Bacillary angiomatosis and the related disorders of bacillary peliosis hepatis and bacillary splenitis are manifestations of infection with Bartonella henselae and Bartonella quintana in immunocompromised persons. B. henselae infection, but not B. quintana infection, is linked to contact with cats and is presumed to cause visceral cat-scratch disease. We reports a case of visceral infection by ...

The search for the infectious agents responsible for cat-scratch disease, bacillary angiomatosis, and related syndromes has a long and often circuitous history. Recognition of the etiologic agents and a new understanding of the fundamental features of the epidemiology and natural history of modern day Bartonella (formerly Rochalimaea)-associated diseases culminate a multipartite story that comb...

Kaposi’s sarcoma is described as cutaneous and extracutaneous neoplasm predominantly affecting older individuals. Though earlier uncommon and endemic to certain African areas, its incidence is on a rise due to infections with human immunodeficiency virus and also due to transplant-associated immunosuppression. Further, certain benign conditions like Pseudo Kaposi’s sarcoma, certain infective co...
