Abstract
Enterohemorrhagic Escherichia coli (EHEC) strains were tested for thei r ability to survive in acid pH at 37 degrees C. No loss of viability was observed in an O157:H7 EHEC strain (ATCC 43895) at pH levels of 3. 0 and 2.5 for at least 5 h. The level of acid tolerance of most EHEC i solates was very high, similar to that of Shigella flexneri strains. T he acid tolerance was dependent on the growth phase and pH of the grow th medium.
