- ... Human pathogenic Escherichia coli O157:H7 produces Shiga-like toxins (SLT) that cause hemolytic uremic syndrome. Typically, SLT are released when a bacterium lyses, but the mechanism of controlling SLT production is not clearly understood. This paper studies the cell growth and metabolism of E. coli in Luria Bertani (LB) broth with and without added sugars. Sugars added to LB broth cause a variety ...

- ... Within 2 months, two water sources in a karst area in Switzerland were sampled 9 times each, and analyzed by real-time PCR for 6 EHEC O-types, Shiga-like-toxin (stx1 and stx2) and intimin (eae) genes. With the exception of O111, 5 O-types were recorded regularly and at high frequencies (O26: 33.3 %; O157: 33.3 %; O104: 66.6 %; O103: 72.2 %; O145: 94.4 %). Genes for Shiga-like-toxins and intimin we ...
