Dogs and cats have gained a special position in human society by becoming our principal companion animals. In this context, efforts to ensure their health and welfare have increased exponentially, with in recent times a growing interest in assessing the impact of the gut microbiota on canine and feline health. Recent technological advances have generated new tools to not only examine the intestinal microbial composition of dogs and cats, but also to scrutinize the genetic repertoire and associated metabolic functions of this microbial community. The application of high-throughput sequencing techniques to canine and feline faecal samples revealed similarities in their bacterial composition, with Fusobacteria, Firmicutes and Bacteroidetes as the most prevalent and abundant phyla, followed by Proteobacteria and Actinobacteria. Although key bacterial members were consistently present in their gut microbiota, the taxonomic composition and the metabolic repertoire of the intestinal microbial population may be influenced by several factors, including diet, age and anthropogenic aspects, as well as intestinal dysbiosis. The current review aims to provide a comprehensive overview of the multitude of factors which play a role in the modulation of the canine and feline gut microbiota and that of their human owners with whom they share the same environment.
狗和猫通过成为我们主要的伴侣动物，在人类社会中获得了特殊的地位。在这种背景下，人们越来越关注肠道微生物群对犬和猫健康的影响，以努力确保它们的健康和福利。最近的技术进步为我们提供了新的工具，不仅可以检查犬和猫的肠道微生物组成，还可以仔细研究这个微生物群落的基因库和相关代谢功能。高通量测序技术在犬和猫粪便样本中的应用揭示了它们细菌组成的相似性，厚壁菌门、拟杆菌门和变形菌门是最常见和丰富的门，其次是放线菌门和 Actinobacteria。尽管其肠道微生物群中始终存在关键的细菌成员，但肠道微生物群的分类组成和代谢谱可能受到多种因素的影响，包括饮食、年龄和人为因素，以及肠道菌群失调。本综述旨在全面概述在调节犬和猫肠道微生物群及其与它们共享相同环境的人类主人的肠道微生物群方面发挥作用的多种因素。
