the results of environmental analyses of staphylococci and the total number of bacteria in the air during 77 operations did not indicate that airborne infection is a major cause of postoperative infections -- there was no difference between the number of bacteria found in the air during operations after which infection occurred and uninfected operations , and the use of special zonal ventilation with high rates of air exchange in the operating area had no effect on the infection frequency .
