Rainbow Agar O157 is designed for the rapid isolation and identification of enterohaemorrhagic Escherichia coli (EHEC), particularly O157, characterised by black colonies. Five-hundred-eighty-five E. coli strains, including O157, O111 and O113 serogroups from many sources were examined on Rainbow Agar O157. EHEC O157 could readily be isolated and recognized uniquely by typical black colonies. Some other EHEC also stand out as blue-black, whereas O113 and some other EHEC strains were mauve, red or pink and indistinguishable from SLT-negative strains of E. coli.
彩虹O157琼脂用于快速分离和鉴定肠出血性大肠杆菌（EHEC），特别是O157，其特征为黑色菌落。在彩虹O157琼脂上检测了585株大肠杆菌菌株，包括来自许多来源的O157、O111和O113血清群。EHEC O157能够通过典型的黑色菌落轻松分离并唯一识别。其他一些EHEC也呈现出蓝黑色，而O113和其他一些EHEC菌株则为淡紫色、红色或粉红色，与大肠杆菌的SLT阴性菌株无法区分。
