Purpose: We researched microbial profiles and the antimicrobial resistance profile of wound infection of the pelvic area in Korea for the recent 5 years in order to provide useful information on the choice of adequate drugs in the treatment of pelvic wound infection.Materials and Methods: We retrospectively analyzed 211 pelvic wound culture samples and their antimicrobial resistance in 198 in- or out-patients of the Urology and Plastic surgery department from January 2010 to December 2014.Results: Of the total samples, Staphylococcus aureus was isolated most frequently (35.3%), followed by Escherichia coli (15.1%), Staphylococcus epidermidis (12.6%), Staphylococcus haemolyticus (12.6%), Staphylococcus lugdunensis (8.4%), Pseudomonas aeruginosa (6.7%), Enterococcus spp. (4.2%), and Streptococcus spp. (3.3%). There were no notable changes of bacterial distribution for 5 years. For Gram-positive isolates, the oxacillin resistance rate for Gram-positive bacteria was 42.6% and showed an increasing tendency for the recent 5 years. Piperacillin, rifampicin, and vancomycin had low resistance for Gram-positive bacteria. Carbapenems, piperacillin/tazobactam had low resistance for Gram-negative bacteria. The Gram-positive organisms were more sensitive to many antibiotics in contrast to the Gram-negative organisms. Conclusions: Of varied causative organisms and susceptibility of the pelvic wound site, the most frequently infected organisms of the pelvic area were S. aureus, followed by E. coli. The methicillin resistive S. aureus (MRSA) incidence showed a tendency to increase yearly, thus selection or early change of antibiotics considering MRSA is recommended if the antibiotic response is poor. Gram-negative bacteria has a higher resistance rate compared with Gram-positive bacteria and had carbapenems and piperacillin/tazobactam. KCI Citation Count: 0
