Abstract: To understand the correlation between drug resistance patterns and biofilm phenotype of Escherichia coli isolated from Wenchang chicken to fifteen drugs,broth microdilution method and improved crystal violet method were used for drug resistance and biofilm-forming ability analysis of 65 Escherichia coli isolated from Wenchang chicken to 15 commonly used drugs.The results showed that 89.23% of the strains were multidrug resistant and 64.62% of which revealed cross resistance;81.54% of the strains had different biofilm-forming ability and only 18.46% of which had no biofilm-forming ability.The results suggested that most of the strains with biofilm-forming ability were multidrug resistant,but there was no significant difference between the strains with biofilm-forming ability and those performed no biofilm-forming ability.

Key words: Wenchang chicken; Escherichia coli; broth microdilution method; biofilm
