Results The distinctive PCR products of the 6 isolated strains from Liaoning and Jilin areas through restriction with Hinf I ,Hha I ,Rsa I appeared two different kinds of RFLP restriction map. The strains HCAa9202,HCAp9203 and HCM9501 had the similar restriction maps with reference strain Gilliam,but they did not have restriction site of Hinf I ;Strains KDCt9402,KDCp9403 and KDCt9404 had the simular testriction map with reference strain Karp.
