AB  - A select group of porcine and bovine Escherichia coli strains capable of causing 
      diarrheal disease in neonatal pigs and calves, respectively, were tested for 
      enterotoxin production and resistance to 23 different antimicrobial agents. 
      Thirty-four of the 39 porcine strains tested were enterotoxigenic; that is, they 
      synthesized heat-stable (ST), together with heat-labile (LT), enterotoxin; ST 
      toxin alone, or LT toxin alone. Fourteen of the 15 bovine strains tested produced 
      ST toxin only, whereas 1 strain elaborated LT toxin only. All of the strains were 
      multiple drug resistant. Among the porcine strains, 2 were resistant to 6 of the 
      antimicrobial agents, and 1 was resistant to 18 of the drugs. All of these 
      strains were resistant to cloxacillin, lincomycin, and penicillin G. None of them 
      was resistant to chloramphenicol, colistin, gentamicin, polymyxin B, or nalidixic 
      acid. One of the bovine strains was resistant to 7 of the drugs, and 1 strain was 
      resistant to 17 of these antimicrobial agents. All of the bovine strains 
      exhibited resistance to cloxacillin, lincomycin, novobiocin, pencillin G, 
      sulfathiazole, sulfamethizole, and triple sulfa (sulfadiazine, sulfamerazine, and 
      sulfamethazine). None of these strains showed resistance to gentamicin, nalidixic 
      acid, nitrofurazone, or nitrofurantoin.
