post-operative wound Infections

Our study have been carried out on 100post-operative wound infections and specimensfrom wounds are collected and examined for bothaerobic and anaerobic micro-organisms.The clean surgical group consists of31 patients including 10 post-splenectomy, 13 post-herniorrhaphy and 8 post-mastectomy operations.The potentially contaminated abdominal group in-volves 33 patients including 13 post-appendectomy,8 post-cholecystectomy and 12 post-colorectal,operations. The urological group contains 20patients of post-renal and post-prostatic andurinary bladder operations. The Gyne. Obstetricgroup contains 16 patients of 10 post-cesareansection and 6 abdominal hysterectomy operations.In clean surgical group, Staph. aureus isthe most common organism isolated in 61.3% followedby streptococcus B.haemolyticus in 12.9% andKlebsiella in 12.9%. On the other hand, the anae-robes are. .isolated in low per cent as Peptococcus(3.2%) and Peptostreptococcus (6.51%).The potentially conta~inated abdominalsurgical group shows high isolation of B.
