CHROMagar O157 is designed for the rapid isolation and identification of enterohaemorrhagic Escherichia coli (EHEC), particularly O157, characterized by pink colonies. Five hundred and eighty-five E. coli strains, including O157, O111 and O113 serogroups, from many sources were examined on CHROMagar O157. Enterohaemorrhagic E. coli O157 could readily be isolated and recognized uniquely by typical pink colonies. Some other EHEC also produced pink colonies, whereas O113 and many other EHEC strains were blue and indistinguishable from Shiga-like toxin-negative strains of E. coli.
CHROMagar O157用于快速分离和鉴定肠出血性大肠杆菌（EHEC），特别是O157，其特征为粉红色菌落。对来自多个来源的585株大肠杆菌菌株（包括O157、O111和O113血清群）在CHROMagar O157上进行了检测。肠出血性大肠杆菌O157能够通过典型的粉红色菌落很容易地被分离和独特识别。其他一些EHEC也产生粉红色菌落，而O113和许多其他EHEC菌株呈蓝色，与大肠杆菌志贺样毒素阴性菌株无法区分。
