DNA probes specific for genes coding for the heat stable enterotoxins (ST-I and ST-II), the heat labile enterotoxins (LT-I and LT-II), Shiga like cytotoxins and for the enterohemorrhagic factor (EHF), were used to examined 150 fecal Escherichia coli isolates from both diarrheic and healthy piglets. Thirty seven percent of the isolates hybridized with the… (More)
Of 135 strains of Escherichia coli from the intestines of healthy and diseased piglets screened, 16 (12%) were positive in a bioassay for aerobactin production. Of these, 15 also carried genetic determinants for heat stable or heat labile enterotoxins.
A DNA probe specific for genes coding for the heat-labile toxin type II (LT-II), heat-stable toxin type Ib (ST-Ib) and Shiga-like toxin type II (SLT-II), were used to examine 118 fecal Escherichia coli strains isolated from healthy pigs. Fifty-six (47.4%) of the isolated were hybridized with the LT-II probe. Thirty-nine strains (33%) possessed ST-Ib genes… (More)
