^aDS: bacterial sensitive to all 13 antibiotics, including ampicillin (AMP), amoxicillin/clavulanate (AMC), cefotaxime (CTX), meropenem (MEM), amikacin (AMK), gentamicin (GEN), colistin (CS), ceftiofur (CEF), ciprofloxacin (CIP), sulfamethoxazole (T/S), tetracycline (TET), tigecycline (TIG), and florfenicol (FFC), was DS bacteria. ^bDR: bacteria resistant to one or two antibiotics were called DR bacteria. ^cMDR: multidrug resistance was defined as resistance to at least three antibiotics.
