Sensitivity and resistance of microorganisms in infected surgical wounds on surgical floor of Mayo Hospital

Abstract

Background: There is an overwhelming concern around the world regarding the increasing number of resistant strains of microorganisms in all sorts of wounds. There is hardly any information about the prevalence and incidence of such resistance pattern in our local hospitals Methods: This study was done to probe into the common microorganisms and their culture sensitivities to antibiotics in surgical wound infections in general surgery wards of Mayo hospital. The study material included the pus specimens sent to pathology lab from general surgical wards. There culture sensitivity results were interpreted to find out the prevalence of individual microorganisms in surgical wounds and sensitivities and resistance to different antibiotics. Results: Staphylococcus aureus was the most common organism cultured (54.87%), followed by E.Coli (10%), pseudomonas(10%), proteus (7.9%) and kleibsiella (5.3%). 20 percent of wounds had mixed growth of organisms. Mixed growth of microorganisms was seen in 20% of cases. Conclusion: Most of the bacteria cultured were resistant to routinely used antibiotics.
