  1. aNT, Non-typeable H-antigen
  2. bDomestic animal samples were collected from distinct regions in the Culiacan Valley, Sinaloa, Mexico [16]
  3. cMIC value indicates resistance to the tested antimicrobial, according to CLSI guidelines [23]
  4. dMIC value indicates an intermediate susceptibility to the tested antimicrobial, according to CLSI guidelines [23]
