Abstract：In order to understand different development groups and its molecular polymorphism of chicken Escherichia coli, 26 chicken Escherichia coli strains isolated from four different cities in Liaoning province were used to identify different development groups and investigate typing with the methods of formation identification and Random Amplified Polymorphic DNA(RAPD). The meth-od of formation identification divides 26 chicken Escherichia coli into 4 development groups with 13 in group A, 3 in group B1, 8 in group B2 and 2 in group D. In RAPD, we selected 2 in 6 random primers which can have a better amplified polymorphic in 26 Escherichia coli and altogether get 7 DNA fragments, strains HLD6、G2、G5、HLD3、HLD4、G7、G11 were in closer relationship in genetics. Howev-er, strain G22 was a little distant to the other 25 Escherichia coli in genetic relationship.
