Aerobic Bacteriological Profile of Post-Operative Surgical Wound Infections and Their Antibiogram in A Tertiary Care Hospital
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 6
Abstract
Background And Objectives: Post-operative wound infections are considered as the commonest nosocomial infections after urinary tract infections and are responsible for the increasing cost, morbidity and mortality prolongs hospital stay. Materials And Methods: Pus samples/ wound swabs were processed and identified by colony morphology, Gram’s stain and biochemical reactions. The antibiotic susceptibility tests were performed by CLSI recommended by Kirby-Bauer disc diffusion method. Results: A total of 112 pus samples from post-operative wound infection from various departments were collected and processed in the department of Microbiology, during the study period. The most common microorganism isolated was Staphylococcus aureus (31.3%), followed by E.coli (26.1%), Pseudomonas sp (18%), CONS (8.2%), Klebsiella spp.(4.5%), Proteus sp.(3.7%), Enterobacter sp (3%), Streptococcus sp (2.2%), Citrobater freundii (1.5%) and Enterococcus sp.(1.5%). Among Gram negative isolates they showed sensitivity to only few available options like Imepenem (92.1%) followed by Amikacin(85.5%) and Piperacillin-Tazobactum (80.3%) and were resistant to most commonly used antibiotics. All Gram positive isolates found to be sensitive to Amikacin(89.7%), Linezolid(100%) and Vancomycin(100%). Conclusion: The incidence of multi-drug resistant pathogens as a cause of postoperative wound infection is rising. Hence routine monitoring of drug susceptibility pattern helps to identify the resistance trends to suggest empirical treatment options to the clinicians
