Following a brief review of the ecology of Escherichia coli in general, the role of Shiga-Toxigenic (Verocytotoxigenic) E. coli (STEC) as pathogens is addressed. While STEC belonging to the serogroup O157 have been extensively studied and shown to be involved in many cases and outbreaks of human disease, the importance of STEC belonging to other serogroups has not been recognized as much. This review addresses the problems associated with these pathogens, demonstrating that increasing the awareness of them is a major part of the problem. This review then demonstrates how widespread isolations especially from food animals and human disease have been, discussing in particular STEC belonging to serogroups O8, O26, O103, O111, O113 and O128. The animal host-specificity of these STEC is also reviewed. In conclusion some methods of improving isolation of these pathogens is addressed.

非O157滋贺毒素（verocytotogenic）大肠杆菌；被低估的病原体。

在简要回顾了大肠埃希氏菌的生态学之后，讨论了志贺毒素（Verocytotoxigenic）大肠杆菌（STEC）作为病原体的作用。尽管对O157血清群的STEC进行了广泛研究，并显示出它与人类疾病的许多病例和疾病爆发有关，但对其他血清群的STEC的重要性尚未得到足够的认识。这篇评论解决了与这些病原体有关的问题，表明增加对它们的认识是问题的主要部分。然后，该综述证明了特别是从食用动物和人类疾病中分离出的广泛分离，特别是讨论了属于血清群O8，O26，O103，O111，O113和O128的STEC。还审查了这些STEC的动物宿主特异性。
