  1. Notes: AMP Ampicillin, AMC Amoxicillin and Clavulafiate, CEP Cephalothin, CIP Ciprofloxacin, CTX Cefotaxime, DEC Diarrheagenic Escherichia coli, GEN Gentamicin, NAL Nalidixic acid, NTS Non–typhoideal Salmonella, REP Rifampicin, SXT Sulfamethoxazole–Trimethoprim, TCY Tetracycline
  2. DEC has been classified into several subtypes based on mechanisms of pathogenicity and clinical feature, such as enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), enteroinvasive E. coli (EIEC), enterohemorrhagic E. coli (EHEC). NTS was discerned with serum agglutination test into S. enteritidis, S. enterica Typhimurium and other Salmonella
