This investigation was performed to isloate and identify the total bacteria, Staphylococcus spp. and fungi from the indoor air exposed for 30 minutes on the blood agar plate at the 27 places in a hospital. Antibiotic susceptibility tests of the isolated bacteria were also studied. The mean numbers of total bacteria, Staphylococci spp. and fungi were 26, 17, and 2 in the summer and 19, 8, and 2 in the winter, respectively. Staphylococcus epidermidis was the most common isolated bacteria, and the next was Staphylococcus aureus, Aerococcus spp., Micrococcus spp., and Bacillus spp. from the indoor-air of hospital. Aspergillus spp., Cephalosporum spp., Curvularia spp., penicillium spp., and Phialophora spp. was frequently isolated from the indoor-air of hospital. The 109 strains of isolated Staphylococcus epidermidis sho-wed resistance to tetracycline(45.0%), methicillin(40.2%), erythromycin(31.2%), and kanamycin(24.8%). The 76 strains of isolated Staphylococcus aureus showed resistance to erythromycin(71.7%), methicillin(63.2%), kanamycin (44.7%), tetracycline(39.5%), and ampicillin(32.9). The 67 strains of isolated Aerococcus spp. showed resistance to erythromycin(26.9%), methicillin(25.4%), kanamycin(22%), and tetracycline(22.4%). The 48 strains of isolated Micrococus spp. showed resistance to tetracycline(27.0%), methicillin(22.9%), erythromycin(22.9%), and kanamycin(20.8%).
