Comparison of phage types of staphylococci from normal and infected eyes in 1960-1965 with those reported in the three previous years confirmed earlier findings that ocular infection is almost always caused by many different phage types which also are found in normal eyes. The proportion of staphylococci sensitive to three chemotherapeutic and eight antibiotic agents was constant during the eight-year period and did not vary with season, source, or phage groups (except for strain 80/81). Sixteen of 36 postoperative infections (1960-1965) were caused by 13 phage types of staphylococci all of which except for 80/81, were similar to types isolated from normal eyes; the other 19 infections were caused by non-typable staphylococci, indicating that most postoperative infections were caused by organisms carried by the patient. No postoperative infections occurred in 1,141 patients receiving intensive antibiotic prophylaxis.
