Aims: There are several biological characteristics that differ between Escherichia coli O157:H7, a dangerous food‐borne pathogen, and the other serotypes of E. coli . Methods and Results: The optimal growth temperatures ( T opt ) were determined for 32 E. coli strains, whether each strain belonged to the O157 serotype or not. The mean values of T opt for the O157 and non‐O157 groups were 40·2 and 41·2°C, respectively. Significance and Impact of the Study: This difference is statistically significant ( P =0·0002) but has no biological implication.
