Spectrum and antibiogram of bacteria isolated from patients presenting with infected wounds in a Tertiary Hospital, northern Tanzania

OBJECTIVE: This study aimed to determine the spectrum and antibiogram of the isolated bacteria from patients presenting with infected wounds at Kilimanjaro Christian Medical Centre in northern Tanzania. RESULTS: Bacterial growth was observed in the vast majority of wound swabs (91.4%). Most of the bacteria isolated (62.3%) were Gram-negative rods. Staphylococcus aureus was the most common isolated organism (16%) followed by other Coliforms and Enterococcus spp. (12.5% each). Enterococcus spp. (36.4%) was the most common isolated bacteria in diabetic wounds whereas S. aureus was the most common isolated bacteria from the wounds caused by trauma (40.0%) and surgical site infection (20.6%). Resistance was high to most common antibiotics used in the hospital.
