Abstract

This study was carried out to investigate the airborne microbial pollution in hospital environment. Using a mechanical air sampler, microbiological samples were taken from intensive care unit, general ward room, patients wailing room and outdoor of 20 hospitals in Seoul, Korea. The concentration of airborne bacteria and fungi ranged 97-410 cfu/㎥ and 37-77 cfu/㎥, respectively and patients waiting room had highest bacterial count. 10 genera of molds were identified and the most frequently recovered molds were Aspergillus, followed by Penicillium, Alternaria and Cladosporium. Among Staphylococcus species, S. haemolyticus and S. epidermidis were predominant and 47% of Staphylococcus species were isolated from intensive rare unit.

서울에 위치한 20개 종합병원의 중환자실, 일반병동 입원실, 환자대기실과 병원 실외 4곳 공기중의 일반 세균수와 곰팡이수를 측정하였으며, 기회 감염균을 검출하였다. 97-410 cfu/㎥의 일반세균수와 37-77 cfu/㎥의 진균이 검출되었으며 중환자실이 가장 낮은 미생물의 오염도를 보였으며 환자대기실이 가장 높은 오염도를 나타내었다. 18종의 진균이 분리되었으며 Aspergillus spp.가 가장 높은 빈도로 검출되었으며, 그 다음으로 Penicillium, Alternaria, Cladosporium 속 등이 검출되었다. Staphylococcus spp. 중에서는 S. haemolyticus와 S. epidermis가 가장 높은 빈도로 검출되었으며 검출된 Staphylococcus spp. 중 47%가 중환자실에서 검출되었다.
