Hemotrophic mycoplasmas infect a variety of mammals. Although infection in humans is rarely reported, an association with an immunocompromised state has been suggested. We report a case of a Mycoplasma haemofelis-like infection in an HIV-positive patient co-infected with Bartonella henselae.

Sera from 38 patients with Kawasaki disease were tested for immunofluorescent antibodies to Ehrlichia chaffeensis, Rochalimaea henselae, and R. quintana Oklahoma. Only 2.5% of the patients tested positive for E. chaffeensis, and 5% were positive for R. henselae and R. quintana Oklahoma. Our data suggest that Ehrlichia and Rochalimaea spp. do not play a unique role in the etiology of Kawasaki di...

BACKGROUND Ticks derived from cats have rarely been evaluated for the presence of pathogens. The aim of this study was to determine the prevalence of Anaplasma phagocytophilum, Bartonella spp., haemoplasma species and Hepatozoon spp. in ticks collected from cats in the UK. METHODS Five hundred and forty DNA samples extracted from 540 ticks collected from cats presenting to veterinarians in UK...

Bartonella spp. are increasingly implicated in infectious endocarditis cases in the UK. Herein, we attempted to quantify their role in this syndrome and explored the epidemiology of Bartonella-associated endocarditis in the UK. Between November 2005 and October 2010, samples from 685 endocarditis patients were submitted to the Health Protection Agency for Bartonella serology. Serological eviden...

Bacillary angiomatosis is a recently described vascular proliferative lesion that occurs most commonly in individuals infected with human immunodeficiency virus. Cutaneous lesions are the most frequently described manifestations of bacillary angiomatosis. However, as culture techniques and disease recognition have improved, additional manifestations have been identified in human immunodeficienc...

We present prevalence of Bartonella spp. for multiple cohorts of wild and captive cetaceans. One hundred and six cetaceans including 86 bottlenose dolphins (71 free-ranging, 14 captive in a facility with a dolphin experiencing debility of unknown origin, 1 stranded), 11 striped dolphins, 4 harbor porpoises, 3 Risso's dolphins, 1 dwarf sperm whale and 1 pygmy sperm whale (all stranded) were samp...

Bartonella henselae is the major etiological agent of cat scratch disease in humans. Cats act as the natural reservoir of B. henselae and can transmit the infection to humans by a bite or scratch. The prevalence of B. henselae in cat populations was evaluated by serological and bacteriological tests. A total of 769 stray cats from three urban and three rural areas in northern Italy were sampled...
