The stability of thermolabile (LT) enterotoxin in 26 strains of porcine enterotoxigenicEscherichia coli (PETEC) belonging to serogroups 08 and 0149 was assayed by the passive immune hemolysis (PIH) test, over a period of 9 months at −70°C. It was found that the percentage of LT+ colonies (% LT+) and the mean value of hemoglobin release (¯XHb), could predict a change from LT+ to LT−.
