區域醫院C特定地點細菌及真菌種類與濃度之研究
A Case Study of the Research of the Airborne Microorganism Types and Concentrations at a Regional Hospital
摘要
存在醫院空氣中之生物氣膠主要來自院內活動之人們。此外，醫護人員在診療病患過程中亦有可能產生生物氣膠，因此本研究採集區域醫院C之某院區有呼吸道疾病病人之周遭環境的生物氣膠，以獲悉該環境之細菌與真菌的種類與數量，初步瞭解細菌與真菌之種類、含量（濃度）是否會對醫護人員造成傷害。研究結果顯示2008年4月24日～2009年9月18日中，在C區域醫院五地點（a～e）經生物氣膠採樣器所採集，且利用TSA培養基培養48小時所得之細菌平均濃度±標準偏差（cfu/m^3）分別為525±380、260±191、561±256、631±320與583±593；而經MEA培養基培養96小時所得之真菌平均濃度±標準偏差（cfu/m^3）分別為336±341、284±135、229±183、226±163及253±183。該些值均低於國內環保署所定之室內空氣品質標準規定的1,500和1,000 cfu/m^3，故該五地點存在之細菌與真菌濃度對院內之病患或活動人員的健康應無影響。此外從該醫院獲得之較多細菌種類為假單胞菌屬、芽孢桿菌屬、西宮皮膚球菌屬及泛菌屬；較多真菌種類為青黴菌屬、擬青黴菌屬和酵母菌屬。

Bioaerosols in hospitals usually include allergens such as fungi, bacteria, actinomycetes and protozoa, and are mainly affected by people who participate within the area. In addition, the concentration level of bioaerosols in a hospital might dramatically increase due to medical related activities and in turn threaten the health of the participants within the area. Therefore, the purpose of this study was aimed at understanding the concentration levels and types of the airborne microorganism at a specific site. It is hoped that the results of the study might help understand if the concentration levels and types of airborne microorganism might put the lives of the medical staff in danger. The data collected from April 2008 to September 2009 at five designated spots showed that the total average bacteria and fungi concentration by using TSA and MEA medium incubated for 48h and 96h were 525 ± 380, 260 ± 191, 561 ± 256, 631 ± 320, 583 ± 593 and 336 ± 341, 284 ± 135, 229 ± 183, 226 ± 163, 253 ± 183 cfu/m^3. Those data are lower than the standard values that Environmental Protection Administration has set for indoor air quality, 1,500 and 1,000 cfu/m^3. Therefore, the samples collected from the 5 designated spots show that the air quality within this specific area should pose no threat to its residents. Besides, the dominant bacteria and fungi types of the Regional Hospital C were Pseudomonas sp., Bacillus sp., Dermacoccus sp. Pantoea sp. and Penicillium sp., Paecilomyces sp., Yarrowia sp.
