A total of 175 isolates were tested. All but two isolates possessed genes for at least one of the enterotoxins or fimbrial adhesins. Nearly all (94.86%) of the isolates that carried enterotoxin genes also carried genes for one of the fimbrial adhesins. The two predominant genotypes were K88 LT STb and F18 STa STb SLT, respectively. ER -
