Bacterial growth and survival in numerous environments are constrained by the action of bacteria-consuming protozoa. Recent findings suggest that bacterial adaptations against protozoan predation might have a significant role in bacterial persistence and diversification. We argue that selective predation has given rise to diverse routes of bacterial defense, including adaptive mechanisms in bacterial biofilms, and has promoted major transitions in bacterial evolution, such as multicellularity and pathogenesis. We propose that studying predation-driven adaptations will provide an exciting frontier for microbial ecology and evolution at the interface of prokaryotes and eukaryotes.
在众多环境中，细菌的生长和生存受到以细菌为食的原生动物活动的限制。最近的研究结果表明，细菌针对原生动物捕食的适应性可能在细菌的持久性和多样性方面发挥重要作用。我们认为，选择性捕食催生了多种细菌防御途径，包括细菌生物膜中的适应性机制，并推动了细菌进化中的重大转变，如多细胞性和致病性。我们提出，研究捕食驱动的适应性将为原核生物和真核生物界面的微生物生态学和进化提供一个令人兴奋的前沿领域。
