We measured airborne particles and bacteria dispersed from human body wearing surgical gowns which were woven by teflon-coated cotton threads. Number of airborne particles from teflon-coated gowns slowly increased as their washing and sterilization cycles increased. But their average number was approximately half of that of pure cotton surgical gowns at the 24 th washing and sterilization cycle.Number of airborne bacteria from teflon-coated gowns had no clear correlation with cycles. It correlated with that from scrub suits which were worn under surgical gowns. Species of airborne bacteria and their percentages from teflon-coated gowns were gram-positive rods 30%, Staphylococcus haemolyticus 23%, S. epidermidis 18% and so on. On the other hand, those from scrub suits were S. haemolyticus 30%, gram-positive rods 28%, S. epidermidis 16% and so on.Drug susceptibility of 106 staphylococcal strains was examined against PCG, PIPC, MCIPC, MPIPC, DMPPC and CEZ. One strain of S. cohnii had resistance against 6 antibiotics, but all other strains were susceptible to 6 drugs with few exceptions.
