Abstract
Stationary phase and the starvation of log-phase cells increased the acid tolerance of Escherichia coli O157:H7 strains. Although the degree of acid tolerance varied, the survival of most O157:H7 strains exceeded that of other, related, pathogens in a synthetic gastric fluid.
摘要
稳定期以及对数期细胞的饥饿状态增强了大肠杆菌O157:H7菌株的耐酸性。尽管耐酸程度有所不同，但在合成胃液中，大多数O157:H7菌株的存活率超过了其他相关病原体。
