Molecular Typing and Biofilm Formation of Escherichia coli O157 in Eastern China

摘要

Escherichia coliO157 is food-horne pathogen that cause diseases in human,which has become a major public health concern worldwide.Food contaminated with E.coli O157 has been identified as a potential source of transmission of these pathogen in human.Thus,this study was performed to detect and characterize E.coli O157 strains isolated from animal feces and food samples in Eastern China,which will help to understand the extent of food contaminated by animal feces.E.coli O157 was isolated and detected in 2.08％ animal fecal samples (18/864)and 1.03％ food samples (2/194),indicating that E.coli O157 was more prevalent in animal fecal than foods.
