Abstract

Bacteria have a range of distinct immune strategies that provide protection against bacteriophage (phage) infections. While much has been learned about the mechanism of action of these defense strategies, it is less clear why such diversity in defense strategies has evolved. In this review, we discuss the short- and long-term costs and benefits of the different resistance strategies and, hence, the ecological conditions that are likely to favor the different strategies alone and in combination. Finally, we discuss some of the broader consequences, beyond resistance to phage and other genetic elements, resulting from the operation of different immune strategies.

摘要

细菌拥有一系列独特的免疫策略,可提供针对噬菌体感染的保护。虽然我们已经对这些防御策略的作用机制有了很多了解,但防御策略为何会进化出如此多样性却不太清楚。在这篇综述中,我们讨论了不同抗性策略的短期和长期成本与收益,以及因此可能单独或组合有利于不同策略的生态条件。最后,我们讨论了不同免疫策略的运作除了对噬菌体和其他遗传元件的抗性之外所产生的一些更广泛的后果。
