越来越多的证据表明,细菌对抗生素的反应受到其他相互作用的微生物存在的显著影响。在确定病原体对抗生素的敏感性时,通常不会考虑这些相互作用。从这个角度来看,我们认为,对抗生素治疗的耐药性和进化反应不应仅仅被视为单个细菌物种的特性,还应被视为病原体所处的微生物群落的一种涌现特性。我们概述了种间相互作用如何影响单个物种和群落对抗生素治疗的反应,以及这些反应如何影响选择的强度,从而可能改变耐药性进化的轨迹。最后,我们确定了未来研究的关键领域,这将有助于更全面地理解细菌群落中的抗生素耐药性。我们强调,认识到生态环境,即病原体之间以及群落内部发生的相互作用,有助于开发更高效的抗生素治疗方法。
Accumulating evidence suggests that the response of bacteria to antibiotics is significantly affected by the presence of other interacting microbes. These interactions are not typically accounted for when determining pathogen sensitivity to antibiotics. In this perspective, we argue that resistance and evolutionary responses to antibiotic treatments should not be considered only a trait of an individual bacteria species but also an emergent property of the microbial community in which pathogens are embedded. We outline how interspecies interactions can affect the responses of individual species and communities to antibiotic treatment, and how these responses could affect the strength of selection, potentially changing the trajectory of resistance evolution. Finally, we identify key areas of future research which will allow for a more complete understanding of antibiotic resistance in bacterial communities. We emphasise that acknowledging the ecological context, i.e. the interactions that occur between pathogens and within communities, could help the development of more efficient and effective antibiotic treatments.
