Enterotoxigenic Escherichia colistrains were isolated from the feces of 34.4% of 64 diarrheaic neonatal piglets on seven farms. Of a total of 518 isolates, 86 (16.6%) were enterotoxigenic and grouped into four phenotypes: K99+ST+(K99 pilus antigen and heat‐stable enterotoxin producing, 36 strains), ST+(37 strains), K88+LT+(K88 pilus antigen and heat‐labile enterotoxin producing, 11 strains), and K88+ST+(2 strains). K99+ST+and ST+isolates showed multiple drug resistance and most of those (58.3% and 56.8%, respectively) belonged to O serogroup 101. A K99+ST+isolate proved to be capable of inducing diarrhea and death in hysterectomy‐produced colostrum‐deprived piglets when orally inoculated. |
