Abstract

OBJECTIVES

To generate baseline data for indoor airborne fungal spores in noncomplaint residential properties (with no moisture/mold-related problems) and to identify home characteristics indicative of elevated fungal levels.

METHODS

Air samples were collected onto petroleum jelly-coated slides from living rooms of 100 residential properties in Leicestershire, United Kingdom, using a Burkard continuous recording air sampler. The slides were examined by microscopy to determine fungal spore concentrations (spores/m3 air/day).

RESULTS

Total indoor fungal spore concentrations were approximately 16% of outdoor concentrations. Abundant indoor fungal genera include Cladosporium, Sporobolomyces, Tilletiopsis, and Didymella, all of which followed seasonal patterns of release and detection. No clear association was shown between outdoor-predominant fungi and home characteristics. In contrast, Aspergillus/Penicillium-type (Asp/ Pen-type) spores were common indoors and exceeded outdoor levels, with the highest concentrations detected in properties over 90 years old (P = .006) and terraced properties (P = .003).

CONCLUSION

Asp/Pen-type spores are found in noncomplaint UK residential properties and mostly in old terraced houses. This study provides guidelines on acceptable levels of Asp/Pen-type spores and other abundant indoor fungal taxa that can be comparatively used in clinical evaluations of fungal exposure-related disease.

摘要

目的

生成无投诉住宅物业（无潮湿/霉菌相关问题）室内空气真菌孢子的基线数据，并确定表明真菌水平升高的家庭特征。

方法

使用 Burkard 连续记录空气采样器从英国莱斯特郡 100 处住宅物业的客厅采集空气样本到凡士林涂层载玻片上。通过显微镜检查载玻片以确定真菌孢子浓度（每立方米空气/天的孢子数）。

结果

室内总真菌孢子浓度约为室外浓度的 16%。丰富的室内真菌属包括枝孢属、节菱孢属、束梗孢属和拟黑粉属，所有这些属都遵循释放和检测的季节性模式。室外优势真菌与家庭特征之间没有明显的关联。相比之下，曲霉/青霉型（Asp/Pen 型）孢子在室内很常见且超过室外水平，在超过 90 年历史的物业（P =.006）和排屋物业（P =.003）中检测到的浓度最高。
