Stony corals are poster child holobionts due to their intimate association with diverse microorganisms from all domains of life. We are only beginning to understand the diverse functions of most of these microbial associates, including potential main contributors to holobiont health and resilience. Among these, bacteria of the elusive genus Endozoicomonas are widely perceived as beneficial symbionts based on their genomic potential and their high prevalence and ubiquitous presence in coral tissues. Simultaneously, evidence of pathogenic and parasitic Endozoicomonas lineages in other marine animals is emerging. Synthesizing the current knowledge on the association of Endozoicomonas with marine holobionts, we challenge the perception of a purely mutualistic coral-Endozoicomonas relationship and propose directions to elucidate its role along the symbiotic spectrum.
石珊瑚是典型的后生动物复合体，因为它们与来自生命所有领域的多种微生物有着密切的联系。我们才刚刚开始了解这些微生物伴侣的各种功能，包括对后生动物健康和恢复力的潜在主要贡献者。在这些微生物中，难以捉摸的内共生菌属（Endozoicomonas）的细菌被广泛认为是有益的共生体，这是基于它们的基因组潜力以及它们在珊瑚组织中的高普遍性和广泛存在。与此同时，其他海洋动物中内共生菌属（Endozoicomonas）的致病性和寄生谱系的证据也在不断涌现。综合当前关于内共生菌属（Endozoicomonas）与海洋后生动物复合体的关联的知识，我们对纯粹互利共生的珊瑚-内共生菌属（Endozoicomonas）关系的看法提出了挑战，并提出了阐明其在共生谱中作用的方向。
