Bacterial contamination of operating theater is a major risk factor for increased incidence of surgical site and nosocomial infections in hospitals. Surveillance study allows for minimizing incidence and implements effective control and preventive measures. This study assessed the bacterial contamination level, bacterial pathogens and their resistance pattern in the two operating theaters in our hospitals.150 specimens were collected from two operating theaters, Main (MOT)(n=80) and Obsteristic and Gyneacology (O&G OT)(n=70) based on pre-identified inanimate items/surfaces and designated points and analyzed using standard microbiological methods. Overall bacterial contamination rate was 56.7%, 40% in MOT and 75.7% in O&G OT. High contamination rate of Staphylococcus aureus, coagulase negative staphylococci and Bacillius spp were recorded in both units. Clinically relevant pathogens, Klebsiella spp, Enterobacter spp, Enterococcus spp, Pseudomonas aeruginosa were recovered from routinely used equipments, with more pathogens from the O&G OT. High resistant to cotrimoxazole, amoxicillin, ampicillin-clauvanic acid, streptomycin, gentamycin, and erythromycin, observed with bacterial isolates from O/G OT. While the findings portray the level of bacterial contamination within the units, the high rate within the O&G OT posses greater risk for postoperative infections, necessitating need for effective cleaning and disinfection practices and adherence to basic standard infection procedures.
