Surgical site infections (SSIs) are an important cause of mortality and morbidity Worldwide, especially common in low and middle income countries. Prevalence of these infections ranges between 5-16 %, contributing to 20 % of health care associated infection. Their source may be exogenous or endogenous. These infections are responsible for increasing the treatment cost, length of hospital stay, hence, a knowledge of the rate of SSIs can help in formulating appropriate policies for timely and accurate management in hospital. A vast majority of microbes present in hospital environment serve as reservoirs for these infections. The present study was done on 450 samples received in Microbiology dept of GMC Jammu over a period of 1 year (May 2018- May 2019) to determine the bacterial isolates causing SSIs and study their antibiogram. 420 samples () showed pure isolates while 20 cases ( %) were of mixed infection. | Antibiogram of aerobic bacterial isolates from surgical site infections in a tertiary care hospital in North India
