Although trench fever appears to be endemic in many areas of the world, recognition of the disease has been handicapped by the difficulties of making a clinical diagnosis and the unavailability of a simple laboratory procedure to establish the etiology. The author describes a method for the in vitro
The vole agent described by Baker in 1946 was studied as an example of a bacterium that has been mistakenly regarded a rickettsia. Unlike rickettsiae, the vole agent killed chicken embryos with great irregularity, multipled primarily at the surface of avian or mammalian cells and not
Rochalimaea quintana, the etiological agent of trench fever, was tested by an agar dilution method for its susceptibility to the following 14 antibiotics: penicillin G, methicillin, ampicillin, cephalothin, vancomycin, doxycycline, tetracycline, erythromycin, chloramphenicol, streptomycin,
BACKGROUND
Bartonella quintana, the etiological agent of bacillary angiomatosis (BA), causes endothelial cell proliferation. Erythromycin has dramatic effects on BA, and the effects are largely unexplained by the compound's bacteriostatic properties. Our aim here was to evaluate the possibility that
Bartonella quintana, the aetiologic agent of trench fever, has recently been implicated in culture-negative endocarditis and bacteraemia amongst homeless people. B. quintana is a fastidious slow-growing organism. A tissue culture system of human endothelial cells was developed in which B. quintana
BACKGROUND
Bartonella (Rochalimaea) quintana is the agent of trench fever and is transmitted by the body louse. We searched for this organism in three alcoholic homeless men with endocarditis.
METHODS
Blood samples were cultured on a human endothelial cell line and on blood agar. Bacteria were
Bartonella quintana has been reported as the cause of trench fever, persistent endocarditis, bacteriaemia and has been isolated with an increasing incidence in clinical specimens from AIDS patients. One of the main pathogenic factors of gram-negative bacteria, including B. quintana, is the
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
BACKGROUND
Bacillary angiomatosis is characterized by vascular lesions, which occur usually in patients infected with the human immunodeficiency virus (HIV). A newly described gram-negative organism, Rochalimaea henselae, has been associated with cutaneous bacillary angiomatosis, but no organism has
Bartonella species are pathogens of emerging and reemerging significance, causing a wide array of clinical syndromes. In North America and Europe, they are increasingly recognized as a cause of culture negative endocarditis, neuroretinitis, and disease among homeless, HIV-infected, and other
