A newly recognized fastidious gram-negative pathogen as a cause of fever and bacteremia.
TLDR
This pathogen may have been unidentified until now Because of its slow growth, broad susceptibility to antimicrobial agents, and possible requirement of blood-cell lysis for recovery in culture, it should be sought as a cause of unexplained fever, especially in persons with defective cell-mediated immunity.
Rochalimaea henselae sp. nov., a cause of septicemia, bacillary angiomatosis, and parenchymal bacillary peliosis
Nine strains of Rochalimaea spp. that were isolated from patients over a period of 4.5 years were characterized for their enzyme activities, cellular fatty acid compositions, and DNA interrelatedness…
Bartonella (Rochalimaea) quintana bacteremia in inner-city patients with chronic alcoholism.
TLDR
B. quintana is a cause of fever, bacteremia, and endocarditis in HIV-seronegative, homeless, inner-city patients with chronic alcoholism and its epidemiologic and clinical features in these patients are characterized.
Isolation of a New Subspecies, Bartonella vinsoniisubsp. arupensis, from a Cattle Rancher: Identity with Isolates Found in Conjunction with Borrelia burgdorferiand Babesia microti among Naturally…
ABSTRACT Bacteremia with fever due to a novel subspecies of Bartonella vinsonii was found in a cattle rancher. The subspecies shared major characteristics of the genus Bartonella in terms of most…
Multicenter Evaluation of the Cepheid Xpert Methicillin-Resistant Staphylococcus aureus (MRSA) Test as a Rapid Screening Method for Detection of MRSA in Nares
TLDR
It is concluded that the Xpert MRSA assay is a simple, rapid, and accurate method for performing active surveillance for MRSA in a variety of health care populations.
Experimental infection of young specific pathogen-free cats with Bartonella henselae.
TLDR
Eighteen 12-week-old specific pathogen-free cats, blood culture- and serum antibody-negative for Bartonella henselae, were randomly allocated to groups and were intravenously inoculated with 10(10) or with saline, developed histopathologic lesions that apparently resolved, and developed B and T lymphocyte responses to infection.
Applications of cellular fatty acid analysis

  • 1 October 1991
TLDR
Information is just beginning to materialize on the usefulness of cellular fatty acids for the identification of gram-positive bacteria and anaerobes, despite the traditional role of GLC in detecting metabolic products as an aid to identification of anaerOBes.
Invasive disease due to Streptococcus pneumoniae in an area with a high rate of relative penicillin resistance.
TLDR
During 1984, a population-based survey of culture-confirmed invasive disease due to Streptococcus pneumoniae among persons who lived in the Oklahoma City, Oklahoma, metropolitan area through the 20 clinical laboratories found rates were highest among infants less than 12 months old and persons greater than or equal to 80 years old.
Polymerase chain reaction-based restriction fragment length polymorphism analysis of a fragment of the ribosomal operon from Rochalimaea species for subtyping
TLDR
Observations indicate that PCR amplification of the spacer + 23S region of the ribosomal DNA of Rochalimaea spp.
Timely culture for mycobacteria which utilizes a microcolony method
TLDR
The microcolony method allows for the easy detection of mixed mycobacterial infections and yields a presumptive identification that facilitates the selection of a confirmatory gene probe test.
