尽管宿主-微生物相互作用在生态和进化过程中的重要性日益受到重视，但仍然缺乏关于某些海洋哺乳动物肠道微生物群落的信息。此外，饮食、环境或宿主的生殖对微生物群落结构的影响是否最大仍然是未知的。为了填补这一知识空白的一部分，我们利用了一个水族馆提供的自然实验与白鲸（Delphinapterus leucas）隶属于家庭Monodontidae，太平洋白边海豚（Laguphynchus eridens）和共同的海豚（Tursiops truncatus）隶属于家庭Delphinidae，和海角毛皮海豹（Arctocephalus pusillus pusillus）隶属于家庭Otariidae。结果表明，鲸鱼，海豚和海狗的微生物群落组成存在显着差异，并表明宿主的繁殖（家庭水平）在塑造微生物群落中发挥着最重要的作用，而不是食物和环境。总的来说，海豚肠道微生物群落的多样性明显低于鲸鱼和海狗。总体而言，肠道微生物群落主要由厚壁菌门和γ-变形菌门组成，还有一些来自拟杆菌门、梭杆菌门和Epsilonbacteraeota。然而，特定的细菌谱系之间的差异分布的海洋哺乳动物群体。例如，毛螺菌科、瘤胃球菌科和消化链球菌科是白鲸肠道中的优势细菌谱系，而对于海狗，莫拉氏菌科和拟杆菌科是主要的细菌谱系。此外，在太平洋白边海豚和普通海豚的肠道微生物群落占主导地位的致病菌，包括产气荚膜梭菌，弧菌，和摩根氏菌，反映了这些动物的健康状况不佳。尽管人们越来越认识到微生物在海洋哺乳动物肠道中的作用，但目前对这些微生物群落的了解仍然严重缺乏。应开展大规模的研究，以揭示不同海洋哺乳动物物种肠道微生物群的作用。
Despite an increasing appreciation in the importance of host–microbe interactions in ecological and evolutionary processes, information on the gut microbial communities of some marine mammals is still lacking. Moreover, whether diet, environment, or host phylogeny has the greatest impact on microbial community structure is still unknown. To fill part of this knowledge gap, we exploited a natural experiment provided by an aquarium with belugas (Delphinapterus leucas) affiliated with family Monodontidae, Pacific white-sided dolphins (Lagenorhynchus obliquidens) and common bottlenose dolphin (Tursiops truncatus) affiliated with family Delphinidae, and Cape fur seals (Arctocephalus pusillus pusillus) affiliated with family Otariidae. Results show significant differences in microbial community composition of whales, dolphins, and fur seals and indicate that host phylogeny (family level) plays the most important role in shaping the microbial communities, rather than food and environment. In general, the gut microbial communities of dolphins had significantly lower diversity compared to that of whales and fur seals. Overall, the gut microbial communities were mainly composed of Firmicutes and Gammaproteobacteria, together with some from Bacteroidetes, Fusobacteria, and Epsilonbacteraeota. However, specific bacterial lineages were differentially distributed among the marine mammal groups. For instance, Lachnospiraceae, Ruminococcaceae, and Peptostreptococcaceae were the dominant bacterial lineages in the gut of belugas, while for Cape fur seals, Moraxellaceae and Bacteroidaceae were the main bacterial lineages. Moreover, gut microbial communities in both Pacific white-sided dolphins and common bottlenose dolphins were dominated by a number of pathogenic bacteria, including Clostridium perfringens, Vibrio fluvialis, and Morganella morganii, reflecting the poor health condition of these animals. Although there is a growing recognition of the role microorganisms play in the gut of marine mammals, current knowledge about these microbial communities is still severely lacking. Large-scale research studies should be undertaken to reveal the roles played by the gut microbiota of different marine mammal species.
