Salmonella bloodstream infection in Ghanaian children.
OBJECTIVE: To examine the frequency of community-acquired salmonella bloodstream infection in Ghanaian children and the occurrence of antibiotic resistance in salmonellae. METHODS: The study comprised 472 patients with a blood culture obtained within 48 h of admission to the pediatric department of Korle Bu Teaching Hospital in Accra, Ghana, over a 3-month period. All Salmonella isolates from blood cultures were speciated and antibiotic susceptibility tests were performed. Clinical data of children with salmonella bloodstream infection were compared to those of controls. Two control groups were identified: all children enrolled in the study without salmonella bloodstream infection (group 1), and those with bloodstream infection due to other organisms (group 2). RESULTS: A pathogen was isolated from 111 children (23.5%), and salmonellae were among the most common isolates (n=24; 21.6%). Among Salmonella strains, S. enteritidis (n=14; 59%) predominated over S. typhi (n=6; 25%). Resistance to several antibiotics was only found in S. enteritidis isolates (n=8; 57%). Children with salmonella bloodstream infection presented more often than controls with severe anemia, jaundice, abdominal pain and distension as well as hepatomegaly and splenomegaly. They were also hospitalized for a significantly longer period, but the case-fatality rate was similar. CONCLUSIONS: Salmonella bloodstream infection, especially due to non-typhoidal strains, is a potential health problem for Ghanaian children and may be complicated by resistance to the commonly available antibiotics.
