This study had for aim to describe epidemiological, clinical and bacteriological aspects of nontyphoidal Salmonella bacteremia in patients with AIDS in the Dakar University Hospital Infectious Diseases Clinic.
This study was made on data recorded between 1January1996 and 31December2005. The strains were identified according to biochemical (API 20E, BioMérieux) and antigenic features. Their susceptibility to antibiotic drugs was tested by antibiogram. Screening for strains secreting of an extended-spectrum betalactamase was performed.
Sixty-two cases of nontyphoidal Salmonella bacteremia were recorded in AIDS patients as follows: Salmonellaenteritidis bacteremia (32 cases), Salmonellatyphimurium bacteremia (11 cases), and Salmonella spp bacteremia (11 cases). The strains were susceptible to ciprofloxacin, ceftriaxone, aztreonam, amoxicillin plus clavulanic acid in at least 92% of the cases. Only 79% of them were susceptible to cotrimoxazole. The lethality rate was 55%.
This lethality rate of nontyphoidal Salmonella bacteremia is high in AIDS patients. Therefore, the priority should be put on prevention and, in patients with AIDS, on food hygiene measures, antiretroviral treatment and efficient chemoprophylaxis. This should prove efficient to reduce incidence of nontyphoidal Salmonella bacteremia.
