医院病区空气真菌分布的监测

OBJECTIVE To supervise the airborne fungal concentration and species distribution in ward of a Certain Hospital of Lan Zhou,in order to provide a reference for the prevention and treatment of the fungal infection in hospital. METHODS Data from 1 Sep 2007 to 30 Oct 2007 were collected from therapeutic department, corridor, duty room, public ward and intensive care unit(ICU), respectively in the department of pediatrics,the pneumology department and the hematology specialty.The finding can 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 fungi collected from the Pneumology Department were Cladosporium spp, Penici l l i um spp, Aragaki spp, Geotrichum capitatum spp in turn. The fungi collected from the hematology specialty were Penici l l i um spp, Aspregilus spp, Cladosporium spp, Geotrichum capitatum spp, Arthrinium spp in turn. There was no significant difference on the airborne fungal concentration before and after sterilizing（P < 0 . 05）. CONCLUSIONS 1.The most prevalent fungi collected from the hospital were Aspregilus spp，Cladosporium spp，Penicillium spp，Arthrinium spp，Geotrichum capitatum spp.2. It demonstrated the fungi are found in the air of the hospital.we should strengthen management control system of sterilization.
