3 *bla*CTX-M (9.7%), and 2 *bla*TEM (6.5%). Our results showed that the genes responsible for the production of *bla*OXA β-lactamases 12/31 (38.7%) were more prevalent in comparison to the genes encoding *bla*TEM, *bla*SHV, and *bla*CTX-M β-lactamases (**Table 3**). From the three classes of integrons (*Int1, Int2*, and *Int3*) assessed among the resistant strains carrying ESBL genes, only 18 *Int1* (58.1%) and 2 *Int3* (19.4%) were detected. The class 3 integron was detected in only EIEC. No class 2 integrons (*Int2*) were characterized from the resistant strains. The coexistence of the three resistance genes (*bla*SHV*, bla*OXA, and *bla*CTX-M) and *Int1* was found in one EHEC (**Table 3**). The *bla*OXA gene (**Figure 2**) was associated with *Int1* (**Figure 3**) in 11 cases (*p* = 0.001), while the *bla*SHV gene was associated with *Int1* in 5 cases (*p* = 0.100).
