宿主相关微生物对于对抗感染和维持健康至关重要。在两栖动物中,某些皮肤相关的细菌抑制真菌病原体Batrachochytrium dendrobaestrium(Bd),但我们对宿主微生物生态学及其在疾病爆发中的作用的理解是有限的。我们从比利牛斯山助产士蟾蜍种群展示地方流行病或流行病的动态采样皮肤相关的细菌和Bd。我们表明,细菌群落不同的生活阶段,很少有共享的类群,在变态的重组指示。我们检测到一个显着的影响变态皮肤微生物群的感染史,减少动物流行病的人群中的细菌多样性和社区结构和预测功能的差异。Bd分离株的基因组测序支持一个单一的介绍比利牛斯山脉,并揭示病原体遗传学和流行病学趋势之间没有关联。我们的研究结果为两栖动物皮肤的微生物生态学提供了一个生态学相关的见解,并强调了宿主微生物群和病原体遗传学在预测疾病结果方面的相对重要性。两栖动物皮肤微生物群落与壶菌病的严重程度密切相关。在这里,作者表明,不同类型的疾病动态(地方病与流行病)与宿主种群中不同的微生物群有关。
Host-associated microbes are vital for combatting infections and maintaining health. In amphibians, certain skin-associated bacteria inhibit the fungal pathogen Batrachochytrium dendrobatidis (Bd), yet our understanding of host microbial ecology and its role in disease outbreaks is limited. We sampled skin-associated bacteria and Bd from Pyrenean midwife toad populations exhibiting enzootic or epizootic disease dynamics. We demonstrate that bacterial communities differ between life stages with few shared taxa, indicative of restructuring at metamorphosis. We detected a significant effect of infection history on metamorph skin microbiota, with reduced bacterial diversity in epizootic populations and differences in community structure and predicted function. Genome sequencing of Bd isolates supports a single introduction to the Pyrenees and reveals no association between pathogen genetics and epidemiological trends. Our findings provide an ecologically relevant insight into the microbial ecology of amphibian skin and highlight the relative importance of host microbiota and pathogen genetics in predicting disease outcome. Amphibian skin microbe communities have been putatively associated with the severity of chytrid fungal disease. Here, the authors show that different types of disease dynamics (enzootic versus epizootic) are associated with different microbiota in the host populations.
