This paper reports the results of environmental surveillance of yeasts in specific areas of two tertiary local hospitals. From March 2007 to February 2008, samples from the air of two public hospitals were collected on a monthly basis. The samples were collected through passive sedimentation method (day and night exposure) of Petri dishes. A total of 240 air samples from 10 hospital environments were analyzed. These environments presented similar contamination levels, from which 80 fungi isolates were isolated: Candida parapsilosis (n = 34), Rhodotorula spp. (19), Trichosporon asahii (11), C. tropicalis (8), C. albicans (4), C. glabrata (1), C. guilliermondii (1), C. krusei (1) and Saccharomyces spp. (1). Regarding the presence of yeasts and climatic conditions, there were 40 strains (50%) in semi-critical areas (natural ventilation) and critical areas (air conditioned). Considering the presence of microorganisms with pathogenic potential, environmental monitoring is necessary to prevent possible hospital infections.
本论文报告了对两家三级地方医院特定区域酵母菌进行环境监测的结果。2007 年 3 月至 2008 年 2 月,每月采集两家公立医院空气中的样本。通过被动沉降法(白天和黑夜暴露)在培养皿中采集样本。对来自 10 个医院环境的 240 个空气样本进行了分析。这些环境呈现出相似的污染水平,从中分离出 80 株真菌:近平滑念珠菌(n=34)、红酵母属(19)、阿萨希丝孢酵母(11)、热带念珠菌(8)、白色念珠菌(4)、光滑念珠菌(1)、季也蒙念珠菌(1)、克柔念珠菌(1)和酿酒酵母属(1)。关于酵母菌的存在和气候条件,在半关键区域(自然通风)和关键区域(空调)中有 40 株(50%)菌株。考虑到存在具有潜在致病性的微生物,环境监测对于预防可能的医院感染是必要的。
