UNLABELLED
Fungal contamination in a University building.
BACKGROUND.: It is recognized that airborne fungi can cause illnesses in humans but data on environmental exposure are still poor. The aim of this study was to evaluate the fungal airborne contamination in a university building.
METHODS.: The study was performed in February and May 2018; air samples were collected, before activity (on Monday) and during activity, (on Friday), both through active (CFU/m) and passive (Index of microbial air contamination, IMA) method. Fungi were identified by using the scotch test.
RESULTS.: In February the median fungal contamination value decreased from 14 CFU/m before activity to 7 CFU/m during activity, while IMA median remains 0. Instead in May both increased during activity (from 87 to 140 CFU/m; from 5.5 to 7.5 IMA). Overall values increased in May compared to February. spp., pp., spp. spp. were the genera most frequently isolated in both months, while in May spp. e spp. were recovered too.
CONCLUSIONS.: Seasonal trend in the levels of fungal contamination of the air was observed, with a statistically significant increase in May. This study represents the first step of a wider study aimed at enhancing knowledge about air fungal contamination.

某大学建筑中的真菌污染
背景
人们认识到空气中的真菌可导致人类患病，但关于环境暴露的数据仍然匮乏。本研究的目的是评估某大学建筑中空气中的真菌污染情况。
方法
本研究于2018年2月和5月进行；在活动前（周一）和活动期间（周五）采集空气样本，采用主动（CFU/m）和被动（微生物空气污染指数，IMA）两种方法。通过胶带试验鉴定真菌。
结果
2月，真菌污染中位数在活动前为14 CFU/m，活动期间降至7 CFU/m，而IMA中位数保持为0。相反，5月两者在活动期间均有所增加（从87增至140 CFU/m；从5.5增至7.5 IMA）。与2月相比，5月的总体数值有所增加。 spp.、pp.、 spp.、 spp.是这两个月中最常分离出的属，而在5月还分离出了 spp.和 spp.。
结论
观察到空气中真菌污染水平存在季节性趋势，5月有统计学意义的增加。本研究是旨在增进对空气真菌污染认识的更广泛研究的第一步。
