兰州某三甲医院病区空气真菌的监测

目的了解医院病区空气中真菌浓度、菌种分布类型。方法2007年10月10～17日,对兰州某三甲医院儿科、呼吸科及血液科的治疗室、走廊、医生值班室、普通病房及监护病房进行空气真菌的分离培养。结果儿科、呼吸科、血液科空气真菌浓度分别为263.43±184.86,72.74±33.22,101.24±57.80 CFU/m3。儿科常见的为分枝孢子菌属、曲霉属、节菱孢属、红色酵母菌;呼吸科常见的为分枝孢子菌属、青霉属、离蠕孢属、头状地霉;血液科常见的为青霉属、曲霉属、分枝孢子菌属、头状地霉、节菱孢属。空气真菌浓度在消毒前(分别为190.03,54.06,124.51 CFU/m3)后(分别为21.30,8.19,16.38 CFU/m3)有显著性差异(P<0.05)。结论兰州某三甲医院空气真菌主要以曲霉(31.00%)、分枝孢子菌属(23.00%)、青霉(18.00%)、节菱孢(6.00%)、头状地霉(4.00%)为主,占到了总菌数的82.00%;真菌广泛存在医院环境中,应当加强医院的消毒管理制度。

Surveillance on Airborne Fungi in A Top-grade Hospital Wards in Lanzhou

Objective To supervise the airborne fungal concentration and species distribution in ward of a top-grade Hospital in Lan Zhou. Methods Data from 10 Oct 2007 to 17 Oct 2007 were collected from therapeutic department,corridor,duty room,public ward and intensie care unit(ICU),respectively in the department of pediatrics,the pneumology department and the hematology specialty.The finding could be obtained by separation culture to fungi.Results The airborne fungal concentration was 263.43±184.86,72.74±33.22,101.24±57.80 CFU/m3 at the department of pediatrics,the pneumology department and the hematology specialty,respectively.The most prevalent fungi collected from the department of pediatrics were Cladosporium spp,Aspregilus spp,Arthrinium spp,Rhodotorula spp in turn.The most prevalent fungi collected from the Pneumology Department were Cladosporium spp,Penicillium spp,Aragaki spp,Geotrichum capitatum spp in turn.The most prevalent fungi collected from the hematology specialty were Penicillium spp,Aspregilus spp,Cladosporium spp,Geotrichum capitatum spp,Arthrinium spp in turn.There was significant difference on the airborne fungal concentration before and after sterilizing(P<0.05).Conclusion The most prevalent fungi collected from the hospital were Aspregilus spp(31.00%),Cladosporium spp(23.00%),Penicillium spp(18.00%),Arthrinium spp(6.00%),Geotrichum capitatum spp(4.00%).It demonstrated the fungi were found in the air of the hospital.We should strengthen management control system of sterilization.
