The recognition of the bacteria family Bartonellaceae , genus Bartonella has expanded during the past decade from the single Bartonella bacilliformis to 17 currently identified species (Table 1). At least six of these ( B. bacilliformis, B. henselae, B. quintana, B. elizabethae , B. clarridgeiae and B. vinsonni arupensis ) are responsible for human diseases. 1,2 The growing knowledge in this fi...

Ectoparasitic arthropods are often vectors of rickettsiosis. We conducted a survey of ectoparasites on U.S. military facilities throughout Japan with the use of specimens submitted by pest control, public health, and veterinary personnel. Over 1,600 individual ectoparasites were collected. Fifteen species were identified, including several significant vectors of human diseases such as scrub typ...

We monitored by blood culture and immunofluorescence assay (IFA) bartonella infection in one dog and eight cats in a household to determine the prevalence and persistence of the infection as well as its transmissibility to humans. Ectoparasite control was rigorously exercised. During a 3-year period, Bartonella clarridgeiae was recovered from one cat on two occasions, and B. henselae was isolat...

Human bartonellosis in North America is mainly associated with Bartonella henselae, and the availability of laboratory diagnostic tools has significantly heightened awareness of the spectrum of human disease that is caused by this bacterium. We detail herein examples of illness in a pediatric population which serve to confirm that B. henselae-associated disease exists in British Columbia. Serop...

Abstract Bed bugs (Hemiptera: Cimicidae) are common, hematophagous ectoparasites of humans and other animals experiencing an international resurgence. Cimicids have been suspected in the transmission many disease agents, including Bartonella species; however, any kind has not yet confirmed natural cycles. spp. transmitted by a variety arthropods, fleas, lice, sand flies, but potential role bed ...

Bartonella ssp. have gained importance as etiologic agents of human disease, both in temperate and tropical regions. Reports of increasing numbers of clinical cases of bartonellosis in Peru (B. bacilli/ormis), documentation of chronic bacteremia in domestic cats with cat scratch fever (B. henselae), and the association of bacillary angiomatosis and parenchymal peliosis (R. henselae and B. quint...

High seroprevalence rates for Anaplasma phagocytophilum (8.8%), Coxiella burnetii (6.4%), Bartonella henselae (9.6%), and Rickettsia typhi (4.1%) in 365 farm workers near Tianjin, People's Republic of China, suggest that human infections with these zoonotic bacteria are frequent and largely unrecognized. Demographic features of seropositive persons suggest distinct epidemiology, ecology, and ri...

Cat-scratch disease (CSD) is the most frequent presentation of Bartonella henselae infection. It has a worldwide distribution and is associated with a previous history of scratch or bite from a cat or dog. CSD affects children and teenagers more often (80%) than adults, and it usually has a self-limiting clinical course. Atypical clinical course or systemic symptoms are described in 5%-20% of p...

Two variants of an organism resembling the ovine hemoplasma, Mycoplasma ovis, were detected by PCR in blood samples from a veterinarian in Texas. Coinfection with similar variants has been described in sheep. This represents the first report of human infection with this organism. The veterinarian was coinfected with Bartonella henselae.

We analyzed the genetic relatedness of blood culture isolates of Bartonella henselae from 2 cats of patients with cat-scratch disease at admission and after 12 months. Isolates from each cat at different times were clonally unrelated, which suggested reinfection by a second strain.
