Objective To understand the phenotypic diversity of toxigenic Vibrio cholerae O1 E1 Tor strains isolated from different provinces in China during the last 50 years.Methods Traditional biotyping testings including susceptibility to polymyxin B,sensitivity to groupⅣphage,Voges-Proskauer test and haemolysis of sheep erythrocytes were conducted.Results Data from Biotype-specific phenotype analysis revealed that only 133 isolates carried the typical E1 Tor phenotypes while the other 251
