Relative Attachment Behaviors of Pathogenic and Nonpathogenic Escherichia coli to Soil Particles: Influence of Soil Physicochemical Properties

摘要: Attachment of Escherichia coli to soil particles influences bacteria transport water sources. Nontoxigenic E. are commonly used as indicators for predicting the fate pathogens and their contamination potential in natural environments. However, few studies have been conducted compare attachment indicator with pathogenic Therefore, objectives this study were O157:H7 nonpathogenic WH09 different soils assess effects physicochemical properties on particles. cell surfaces tested suspensions much less negatively charged more hydrophobic than WH09, which resulted greater amounts Pearson correlation analysis between partition coefficient (Kd) showed was correlated orga...
