Bartonella spp. in deer keds, Lipoptena mazamae (Diptera: Hippoboscidae), from Georgia and South Carolina, USA.

Deer keds, Lipoptena mazamae (Diptera: Hippoboscidae), were collected from white-tailed deer (Odocoileus virginianus) and humans in Georgia and South Carolina, USA (1 October 2001-6 January 2005) and screened for the presence of DNA from Bartonella spp. Forty deer keds were screened for Bartonella spp. by polymerase chain reaction using primers specific to the riboflavin synthase gene (ribC) of Bartonella. Bartonella species closely related to Bartonella schoenbuchensis and to the etiologic agent of cat-scratch disease (Bartonella henselae) were detected in 10 keds and one ked, respectively.

[Bartonella henselae endocarditis. Report of a case and review of the literature].

Bartonella spp are small Gram-negative rods, aerobic and highly fastidious. They are difficult to culture, in the routine bacterial cultures. They are considered as emergent human pathogens. Since 1993, three species of Bartonella (B. quintana, B. henselae, and B. elizabethae) have been described as causative agents of infectious endocarditis. In this paper we describe the case of a 43 year-old woman with a previous valvular heart disease, probably of rheumatic origin, owner of cats, that suffered an infectious endocarditis by Bartonella henselae in the aortic valve. This patient presented IgG titers against B. henselae of 1/4096 and against B. quintana of 1/256. She also had low IgM titers against B. henselae and B. quintana: 1/64 and 1/32, respectively. The patient received antibiotics for 12 weeks and suffered a valvular replacement due to the severe lesion on the aortic valve. On the endocardiac tissue of the removed valve DNA of B. henselae was detected (polymerase chain reaction-based assay). Clinical evolution of the patient was good. Diagnosis of Bartonella spp infection must be considered in every patient with infectious endocarditis and negative blood cultures, and particularly B. henselae in patients with previous valvular heart disease and regular contact with cats.

[Is there chromomycosis in Spain?].

The first case of autochthonous chromomycosis in Spain is described by the author. The patient lived in the Valencia province and the mycologic investigation was carried out by Prof. Dante Borelli of Venezuela.

[Bartonellosis].

In the last years the number of Bartonella species significantly raised, often with an epidemiological profile of emergent disease. B. bacilliformis is the etiological agent of Carrion's disease. B. clarridgeiae has been associated, together with B. henselae, to Cat-Scratch Disease (CSD), whereas B. elizabethae to endocarditis and B. grahamii to neuroretinitis. B. henselae has been associated to CSD and, in patients with immunodeficiency, together with B. quintana, to bacillary angiomatosis, to peliosis and to endocarditis. B. quintana is the etiological agent of "trench fever", in its "classical" and "urban" form. B. vinsonii subsp. arupensis and subsp. berkhoffii have been associated to bacteremia and endocarditis. The diagnosis foresees pathological examination of the lesions, germ isolation and use of specific serological test and of polymerase chain reaction. Prognosis is, generally, favourable. Therapy foresees the use of numerous antibacterial agents, like: penicillins, cephalosporins, aminoglycosides, tetracyclines, macrolides, quinolones, trimethoprim-sulfomethoxazole and rifampicin.

Chronic osteomyelitis associated with cat-scratch disease.

Cat-scratch disease (CSD) is usually a self-limited illness, though atypical presentations of infection with Bartonella henselae can occur, including osteomyelitis, oculoglandular syndrome, and granulomatous hepatitis. We describe a 6-year-old boy who had atypical CSD osteomyelitis of the left proximal femoral metaphysis due to a cat scratch. This is the second paper to report serial serology of B henselae, and the second paper to identify plasma cells on histologic examination, compatible with chronic osteomyelitis. The diagnosis was made by clinical, serologic, and histologic examination. Sixteen cases of atypical CSD osteomyelitis have been reported in the English literature and are reviewed in this paper.
