Serum specimens from 114 patients hospitalized with a febrile illness were tested with an indirect immunofluorescence assay (IFA) using Bartonella antigens prepared from 6 species of sigmodontine rodents and 3 known human Bartonella pathogens: B. henselae, B. quintana, and B. elizabethae. Acute- and convalescent-phase serum samples from 5 of these patients showed seroconversion with an IFA tite...
We compared the sensitivities and specificities of indirect fluorescent antibody tests developed in our laboratory and commercially available from Focus Technologies (FT; formerly MRL Diagnostic) for detection of serum antibodies to Bartonella spp. Serum samples tested were from patients with culture- or PCR-confirmed Bartonella quintana or B. henselae infections causing cat scratch disease (CS...
In order to identify immunoreactive Bartonella henselae proteins, B. henselae antiserum from an experimentally infected cat was used to screen a B. henselae genomic DNA expression library. One immunoreactive phage clone contained a gene (p26) with significant nucleotide identity with orthologs in brucellae, bartonellae, and several plant-associated bacteria. p26 gene sequences from four B. hens...
BACKGROUND Both endocarditis and Bartonella infections are neglected public health problems, especially in rural Asia. Bartonella endocarditis has been described from wealthier countries in Asia, Japan, Korea, Thailand and India but there are no reports from poorer countries, such as the Lao PDR (Laos), probably because people have neglected to look. METHODOLOGY/PRINCIPAL FINDINGS We conducte...
To the Editor: Bartonella hense-lae is the causative agent of cat-scratch disease, which is the most common form of human bartonellosis (1). In immunocompromised patients, e.g., HIV-infected patients, B. henselae can give rise to longstanding fever, bacil-lary angiomatosis, and peliosis hepatitis (2). Domestic cats are the reservoir for B. henselae, and cat fl eas transmit the organism between ...
The isolation of Bartonella henselae, the agent of cat scratch disease, from the blood of naturally infected domestic cats and the demonstration that cats remain bacteremic for several months suggest that cats play a major role as a reservoir for this bacterium. A convenience sample of 205 cats from northern California was selected between 1992 and 1994 to evaluate the B. henselae antibody and ...
Bartonella henselae is able to internalize endothelial progenitor cells (EPCs), which are resistant to the infection of other common pathogens. Bacteroides fragilis is a gram-negative anaerobe belonging to the gut microflora. It protects from experimental colitis induced by Helicobacter hepaticus through the polysaccharide A (PSA). The aim of our study was to establish: 1) whether B. fragilis c...
There are four Bartonella species known to be pathogenic for humans (Table 1). Carrion’s disease (Bartonella bacilliformis) is endemic to certain areas of South America and has a clinical course that varies widely. It may occur as a subclinical latent disease, an acute fulminant and fatal febrile illness, or an insidious disease of the skin. Trench fever (Bartonella quintana) is transmitted by ...
