真菌经常暴露在不断变化的环境中,必须不断适应以保持其适应性。当变化发生迅速且朝向更苛刻的条件时尤其如此--例如,病原真菌在感染宿主时以及在感染的不同阶段所遇到的情况。在这里,我们提供了一个概述的作用,小规模的遗传交换的健身人类病原真菌。这些改变可以影响宿主-真菌的相互作用,从而影响感染的结果。我们提出了最近的实验和观察处理的重要性的遗传多样性和以前的选择压力的感染池。此外,我们还讨论了特定的生态位和疾病进展以及抗真菌治疗对体内真菌微进化的作用。我们的结论是,不同的机制,小规模的遗传变化允许致病真菌,以增加其健身在主机,从而可以改变感染的过程。
Fungi are frequently exposed to changing environments and must adapt continuously to retain their fitness. This is especially true when changes occur rapidly and toward harsher conditions – a situation, for example, encountered by pathogenic fungi when they infect a host and during the different stages of infections. Here we provide an overview of the role of small-scale genetic exchanges for the fitness of human pathogenic fungi. These alterations can influence host-fungus interactions, and hence the outcome of an infection. We present recent experiments and observations dealing with the importance of the genetic diversity and previous selection pressures of the infecting pool. In addition, we discuss the role of specific niches and disease progression as well as antifungal treatment on fungal microevolution in vivo. We conclude that different mechanisms of small-scale genetic changes allow pathogenic fungi to increase their fitness in the host, and can thus alter the course of infections.
