Abstract

The goal of this study was to examine whether the Environmental Relative Moldiness Index (ERMI) scale created for United States (U.S.) homes was applicable in the assessment of mold contamination for Australian homes. Settled-dust samples were collected in south-eastern Australian homes (n=76) being investigated for possible water-damage and mold contamination. The 36 ERMI molds were quantified in each sample using mold specific quantitative PCR (MSQPCR) and the ERMI value for each home calculated. These homes were then matched to homes in the U.S. with nearly identical ERMI values and the average log10 concentration of each of the 36 molds statistically compared. Most of the 36 ERMI molds were found in Australian water-damaged homes in comparable concentrations to ERMI-matched U.S. homes. The U.S. ERMI scale might provide reasonable estimates of mold contamination in water-damaged Australian homes.

澳大利亚和美国受水破坏房屋中霉菌数量的比较
本研究的目的是检验为美国家庭创建的环境相对霉菌指数(ERMI)量表是否适用于评估澳大利亚家庭的霉菌污染。在澳大利亚东南部的住宅(n=76)中收集了沉降的灰尘样本,正在调查可能的水损害和霉菌污染。使用霉菌特异性定量PCR(MSQPCR)对每个样本中的36种ERMI霉菌进行定量,并计算每个家庭的ERMI值。然后将这些家庭与ERMI值几乎相同的美国家庭进行匹配,并对36种霉菌的平均log10浓度进行统计比较。36种ERMI霉菌中的大多数是在澳大利亚被水破坏的房屋中发现的,其浓度与ERMI匹配的美国房屋相当。美国ERMI规模可能会对澳大利亚受水损害的房屋中的霉菌污染提供合理的估计。
