Disseminated infection with organisms of the Mycobacterium avium complex (MAC) is a common complication of AIDS in the United States and other developing countries, but it is rare or absent in sub-Saharan Africa. To assess the comparative likelihood of exposure to MAC in these geographic areas, we used a standard protocol to culture 91 water samples from(More)
Strict case definitions were applied to 123 clinically diagnosed cases of infective endocarditis. Cases were categorized as definite (19), probable (44), or possible (41) endocarditis or were rejected (19). Compared to other published studies, our patients had an advanced mean age (57), high incidence of underlying valvular disease (66%), short mean(More)
BACKGROUND We sought to determine the prevalence of active tuberculosis among ambulatory HIV-infected persons in Tanzania with CD4 cell counts of > or =200 cells/mm3 and a bacille Calmette-Guerin vaccination scar. METHODS Subjects who volunteered for a tuberculosis booster vaccine trial were screened for active tuberculosis by obtainment of a history,(More)
The source of Mycobacterium avium infection in AIDS has not been identified and it is not known whether most patients with AIDS acquire the organism from recent infection or by reactivation of previous infection. As part of a prospective epidemiological study, we isolated multiple colonies of M avium from patients with AIDS and from potable water to which(More)
In the present study, 8 patients with soft tissue infection due to Mycobacterium marinum are described, and contemporary data on treatment are reviewed. Six patients had positive cultures, all patients had cutaneous exposure to fish tanks, 7 had sporotrichoid lesions, and 2 had deep infection. All 7 tested patients had tuberculin skin test reactions > or(More)
OBJECTIVE to determine the rate of disseminated infection due to non-tuberculous mycobacteria (NTM) among Finnish AIDS patients, and to analyse the epidemiology of these infections. METHODS in a prospective cohort study HIV-infected patients with CD4 counts < 200 x 10(6)/l were interviewed, and had mycobacterial blood cultures performed at baseline and at(More)
BACKGROUND Malassezia species are lipophilic yeasts that are emerging as nosocomial pathogens, particularly in low-birth-weight neonates who receive lipid emulsions. When a cluster of patients with Malassezia pachydermatis infection was identified in an intensive care nursery, we initiated an investigation. METHODS A case patient was defined as any infant(More)
OBJECTIVE To determine whether a multiple-dose series of an inactivated whole cell mycobacterial vaccine, Mycobacterium vaccae, can prevent HIV-associated tuberculosis. DESIGN AND METHODS The DarDar trial was a randomized, placebo-controlled, double-blind trial. The study was carried in an outpatient facility in Dar es Salaam, Tanzania. HIV-infected(More)
Outpatient parenteral antibiotic therapy (OPAT) for infective endocarditis (IE) is being applied widely, despite the absence of controlled data that demonstrates that outcomes are equivalent to those with standard inpatient antibiotic therapy. We review existing OPAT guidelines, published data on the timing of complications from IE, and data on risk factors(More)
