Antibiotic resistance profiles of bacteria isolated from surgical wounds in tertiary hospitals, Tanzania

A surgical wound infection can develop at any time from two to three days after surgery until the wound has healed (usually 2 to 3 weeks post operation). Occasionally, an infection can occur several months after an operation (Humphreys, 2009; Anderson, 2011). Most surgical wound infections are limited to the skin, but can spread to deeper tissues as consequence of microbial invasion/infections, of which majority are caused by human normal flora. Most chronic infections of wounds are colonized with different microorganisms, especially problematic bacteria like antimicrobialresistant Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus, which represent an increasing therapeutic challenge in wound management. It is therefore essential to specify the bacteria in surgical wounds for an individual-specific treatment.
