性选择预示着配偶选择会增加个体的适应性。寄生虫（从真核生物到细菌或病毒）的感染可以降低个体的适应性，改变受感染个体的性特征和分子线索。在这种情况下，人们会期望在配偶选择过程中观察避免感染的机制。在配偶选择方面，绝大多数宿主对感染的反应都是为了避免感染，但配偶选择的成本也会阻碍感染的避免。本文着重指出了现有知识和经验实验的主要局限性，并总结了检验配偶选择中避免感染假说时应考虑的关键因素：所隐含的生物学相互作用中宿主-寄生虫协同进化的时间、被测个体的选择性别（男性、女性或两者）以及被测个体的遗传背景。(C)2014年动物行为研究协会。由爱思唯尔有限公司发布。保留所有权利。
Sexual selection predicts that mate choice increases individual fitness. Infection by parasites (from eukaryotes to bacteria or viruses) can reduce this individual fitness, altering the infected individuals' sexual traits and molecular cues. In this case, one would expect to observe mechanisms for avoiding infection during mate choice. The vast majority of host responses to infection in terms of mate choice are intended to avoid infection, but the costs of mate choice can also hinder infection avoidance. This paper highlights the main limitations in current knowledge and empirical experiments, and summarizes the key factors that should be taken into account to test the hypothesis of infection avoidance in mate choice: the time of host-parasite coevolution in the biological interaction implied, the choosy sex tested (male, female or both) and the genetic background of the individuals tested.
