The presence of airborne fungi in Intensive Care Unit (ICUs) is associated with increased nosocomial infections. The aim of this study was the isolation and identification of airborne fungi presented in an ICU from the University Hospital of Pelotas - RS, with the attempt to know the place's environmental microbiota. 40 Petri plates with Sabouraud Dextrose Agar were exposed to an environment of an ICU, where samples were collected in strategic places during morning and afternoon periods for ten days. Seven fungi genera were identified: Penicillium spp. (15.18%), genus with the higher frequency, followed by Aspergillus spp., Cladosporium spp., Fusarium spp., Paecelomyces spp., Curvularia spp., Alternaria spp., Zygomycetes and sterile mycelium. The most predominant fungi genus were Aspergillus spp. (13.92%) in the morning and Cladosporium spp. (13.92%) in the afternoon. Due to their involvement in different diseases, the identified fungi genera can be classified as potential pathogens of inpatients. These results reinforce the need of monitoring the environmental microorganisms with high frequency and efficiently in health institutions.
重症监护病房（ICU）中空气传播真菌的存在与医院感染的增加有关。本研究的目的是分离和鉴定佩洛塔斯大学医院 - 南里奥格兰德州重症监护病房中存在的空气传播真菌，试图了解该场所的环境微生物群。将40个装有沙氏葡萄糖琼脂的培养皿暴露于重症监护病房的环境中，在十天的上午和下午时段在战略地点采集样本。鉴定出七个真菌属：青霉属（15.18%），频率最高的属，其次是曲霉属、枝孢属、镰刀菌属、拟青霉属、弯孢属、链格孢属、接合菌纲和无菌菌丝体。最主要的真菌属在上午是曲霉属（13.92%），在下午是枝孢属（13.92%）。由于它们与不同疾病有关，鉴定出的真菌属可归类为住院患者的潜在病原体。这些结果强化了在卫生机构中高频且有效地监测环境微生物的必要性。
