The increasing concern with bioaerosols in large office buildings prompted this prospective study of airborne fungal concentrations in a newly constructed building on the Gulf coast. We collected volumetric culture plate air samples on 14 occasions over the 18-month period immediately following building occupancy. On each sampling occasion, we collected duplicate samples from three sites on three floors of this six-story building, and an outdoor sample. Fungal concentrations indoors were consistently below those outdoors, and no sample clearly indicated fungal contamination in the building, although visible growth appeared in the ventilation system during the course of the study. We conclude that modern mechanically ventilated buildings prevent the intrusion of most of the outdoor fungal aerosol, and that even relatively extensive air sampling protocols may not sufficiently document the microbial status of buildings.
对大型办公建筑中生物气溶胶的日益关注促使了这项对墨西哥湾沿岸一座新建建筑中空气传播真菌浓度的前瞻性研究。在建筑物投入使用后的18个月内，我们在14个不同时间收集了体积培养皿空气样本。在每次采样时，我们从这座六层建筑的三层的三个地点采集了两份重复样本，以及一份室外样本。室内真菌浓度一直低于室外，尽管在研究过程中通风系统中出现了可见的生长，但没有样本明确表明该建筑存在真菌污染。我们得出结论，现代机械通风建筑可防止大多数室外真菌气溶胶的侵入，而且即使是相对广泛的空气采样方案也可能不足以充分记录建筑物的微生物状况。
