The main Enterobacteriaceae habitat is the mammal gastrointestinal tract. In most cases, this group of species displays a symbiotic relationship with its hosts. However, some groups may be pathogenic to humans, such as Shiga toxin-producing Escherichia coli and enteroaggregative Escherichia coli. The presence of these groups represents a direct risk to consumers, and recent serotypes displaying the presence of pathogenic genes in both groups are a novel challenge for food production. Thus, microbiological control strategies presenting accurate detection methodologies are required. However, with the appearance of mutations among different species, knowledge, genetic monitoring, and bioinformatics techniques must be expanded. In addition, as a strategy to ensure safe products on an industrial scale, the monitoring by different techniques and fundamentals should be applied throughout the entire processing chain. Therefore, the aim of this review is to describe the pathogenesis mechanisms of different groups, mutant strain dispersion, and current and alternative epidemiological investigation methods.
肠杆菌科的主要栖息地是哺乳动物的胃肠道。在大多数情况下，这组物种与其宿主之间存在共生关系。然而，有些群体可能对人类具有致病性，例如产志贺毒素大肠杆菌和聚集性大肠杆菌。这些群体的存在对消费者构成了直接的风险，而最近出现的一些血清型在这两个群体中都存在致病基因，这对食品生产来说是一个新的挑战。因此，需要采用能够进行准确检测的微生物控制策略。然而，随着不同物种之间出现突变，必须扩大知识、遗传监测和生物信息学技术。此外，作为确保工业规模安全产品的策略，应在整个加工链中应用不同技术和基础的监测。因此，本综述的目的是描述不同群体的发病机制、突变株的分散以及当前和替代的流行病学调查方法。
