The objective of this study was to establish a national relative moldiness index for homes in the United States.
As part of the Housing and Urban Development's American Healthy Homes Survey, dust samples were collected by vacuuming 2 m in the bedrooms plus 2 m in the living rooms from a nationally representative 1096 homes in the United States using the Mitest sampler. Five milligrams of sieved (300 mum pore, nylon mesh) dust was analyzed by mold-specific quantitative polymerase chain reaction for the 36 indicator species in 1096 samples.
On the basis of this standardized national sampling and analysis, an "Environmental Relative Moldiness Index" was created with values ranging from about -10 to 20 or above (lowest to highest).
The Environmental Relative Moldiness Index scale may be useful for home mold-burden estimates in epidemiological studies.
本研究的目的是建立美国住宅的全国相对霉变指数。
作为住房和城市发展部美国健康住宅调查的一部分，使用Mitest采样器，从美国具有全国代表性的1096户家庭的卧室2米处和客厅2米处通过吸尘收集灰尘样本。对1096个样本中的36种指示菌种，通过霉菌特异性定量聚合酶链反应分析5毫克过筛（300微米孔径，尼龙网）灰尘。
基于这种标准化的全国采样和分析，创建了一个“环境相对霉变指数”，其值范围约为-10至20或更高（从最低到最高）。
环境相对霉变指数量表可能有助于流行病学研究中的家庭霉菌负担估计。
