Abstract
Uropathogenic Escherichia coli starved in artificial urine, showed a progressive decline in viability. The presence of betaine in the urine did not significantly increase the survival rate as assessed by plate counts and by measuring the metabolic activity of the population. Previous growth of the starved population in betaine or tryptone did not enhance survival.
摘要
在人工尿液中饥饿培养的尿路致病性大肠杆菌，其活力呈逐渐下降趋势。通过平板计数和测量菌群体代谢活性评估发现，尿液中甜菜碱的存在并未显著提高其存活率。饥饿菌群体先前在甜菜碱或胰蛋白胨中生长，也并未提高其存活率。
