Acid tolerance of enterohemorrhagic Escherichia coli.

M M Benjamin1, A R Datta.   

Abstract

Enterohemorrhagic Escherichia coli (EHEC) strains were tested for their 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 isolates was very high, similar to that of Shigella flexneri strains. The acid tolerance was dependent on the growth phase and pH of the growth medium.
