Seasonal changes of bacterial dispersion from human body surface were found under the fully air-conditioned environment. Airborne bacteria dispersed from human body were sampled by Reyniers modified slit sampler for 148 times. The number of airbone bacteria in summer was the largest and significantly different from that of other three seasons(p<0.05).Numbers of airborne bacteria in spring and autumn were nearly identical. That of winter was the smallest and significantly different from all other seasons(p<0.01). Bacterial dispersion in winter was approximately one fifth of the number in summer, and its standard deviation was the smallest in all seasons. Spesies of airborne bacteria and their percentage dispersed form human body were Staphylococcus aureus 0.1%, coagulaee negative staphylococci 36.8%, micrococci 30.6%, gram-positive rods 30.6%, gram-negative rods 1.7%, yeasts and fungi 0.2%, and others 0.1%.Airborne gram-negative rods were identfied as Moraxella, Pseudomonas paucimobilis and glucose non-fermenting bacteria.
