Forty episodes of invasive group B streptococcal infections in nonpregnant
adults at Chris Hani Baragwanath Hospital, Soweto, South Africa, were retro
spectively reviewed. The mean age of the patients was 45.6 years. Twenty (5
0%) patients were bacteraemic. Common predisposing conditions included diab
etes mellitus (27.5%), trauma (25%), and HIV infection (12.5%), Soft tissue
abscesses and pneumonia accounted for 70% of the presentations. Ten (25%)
patients had acquired the infection nosocomially. Death occurred in 14 (35%
) patients and was significantly associated with bacteraemia (P=0.0009) and
pneumonia (P=0.0012). Trauma is an important predisposing condition, and H
IV infection may have played a role in the setting described; both factors
probably accounted for the relatively young age of the patients.
