Abstract
Wound infections continue to be problematic in clinical practice where empirical treatment of infections is routine. A retrospective study was carried out where records of wound swab samples from patients with different kinds of wounds receiving treatment at the department of Surgery in a peripheral hospital in Nasik were analysed. All none healing ulcers, burn wounds, diabetic foot ulcers, traumatic wounds, abscesses, surgical site infections were included in the study and wound swabs were obtained and culture and sensitivity tests were carried out. Out of 119 wound swabs sent for culture and sensitivity, 110 samples (92.43%) revealed significant bacterial growth indicative of wound infection whereas 9 samples (7.56%) showed no growth. Most patients from whom micro organisms grew were males (83.19%) and the age group most commonly involved was 30-40 years (28.57%).No sample grew more than one organism. Staph aureus was the most commonly isolated organism (66.36%). The bacterial isolates exhibited a high degree of resistance to the antibiotics tested with most isolates showing resistance from 5.56 % as in Chloramphenicol to 90.90% as seen in Imipenem.High resistance levels were found with Imipenem, Ampicillin, Augmentin, Cloxacillin, Carbenicillin, Ceftriaxone, Ceftazidime. The study showed moderate resistance to Ofloxacin, Ciprofloxacin, Azithromycin and Tiecoplanin. Low antibiotic resistance was seen with Chloramphenicol, Gentamycin, Amikacin, Clindamycin, Erythromycin, Levofloxacin, Linezolid, Polymyxin B, Piperacillin, Tobramycin, Vancomycin, Tetracyclin and Netilmycin.
