^aAntibiogram of each isolate was determined by the resistance to antimicrobials ampicillin (A), chloramphenicol (C), ciprofloxacin (Ci), ceftriaxone (Cr), cefazolin (Cz), enrofloxacin (En), flumequine (Ub), streptomycin (S), sulfamethoxazole-trimethopriem (Sxt), tetracycline (T). The association of resistance type with antibiogram was the followings: resistance type A for antibiogram S, B for Ub, C for UbS, D for ST, E for SxtUb, F for CSTUb, G for ASSxtTUb, H for ACSSxtT, I for CSSxtTUb, J for ACSSxtTUb, K for ACEnSSxtTUb, L for ACCiEnSxtTUb, and M for ACCiEnSSxtTUb.

^bPFGE genotypes was determined by 3 band differences between two isolates [Figure 1, [32]].

^cPlasmid was analyzed by Kado and Liu method (30, supplementary Figure 1). Plasmid profile was determined by plasmid size and number (supplementary Table 2).
