在15个手术室和两个血液科进行了为期8年的真菌环境监测。每年在每个房间进行两次采样，平面使用接触板，网格使用无菌拭子。由一九九二年至一九九九年，该署共对17个单位的个别房间进行了1 094次抽样调查，共收集了3 822个样本。1992年至1999年间，无真菌房间的百分比定期增加（分别为41.1%和74.8%）。根据8年期间的真菌污染情况对这些单位进行分类：需要最高保护的手术室（心脏科、胸外科、血管科、手外科、骨科和神经外科）和成人血液科的污染最少（71.8%的房间为阴性）。分离到的最常见的菌种是青霉属。(28.4%）、枝孢属（Cladosporium spp.）(15.6%）和曲霉属（Aspergillus spp.）(7.6%).烟曲霉很少分离（3.7%），主要在研究开始时分离。这项研究表明，环境控制方案是有效的，在减少环境霉菌污染，并可能是有用的，在建立暴露准则，特别是通过定义一个可接受的水平，在风险区的生物污染。(C)2002年，医院感染协会。
An eight-year fungal environmental surveillance was carried out in 15 operating theatres and two haematological units. Sampling was performed twice a year in each room, using contact plates for plane surfaces and sterile swabs for grids. From 1992 to 1999, individual rooms in the 17 units were sampled on 1094 occasions and 3822 samples were collected. The percentage of rooms without fungus increased regularly between 1992 and 1999 (41.1% and 74.8%, respectively). The units were classified according to the fungal contamination during the eight years: the operating theatres which required the highest protection (cardiological, thoracic, vascular, hand, orthopaedic and neurosurgery) and the adult haematological unit showed least contamination (71.8% rooms were negative). The most frequent species isolated were Penicillium spp. (28.4%), Cladosporium spp. (15.6%) and Aspergillus spp. (7.6%). Aspergillus fumigatus was rarely isolated (3.7%), and was mainly isolated at the beginning of the study. This study demonstrates that environmental control programmes are effective in reducing environmental mould contamination and could be useful in establishing exposure guidelines, especially by defining an acceptable level of biocontamination in zones at risk.
