进化免疫学和疾病生态学领域的一个核心挑战是了解宿主对传染病易感性的自然变异的原因和后果。随着宿主在野外从出生到死亡,它们暴露于各种各样的微生物,这些微生物影响它们的身体状况,免疫系统成熟以及对并发和未来感染的易感性。因此,多次暴露于相同或不同的微生物可能是宿主免疫变异和免疫启动的重要环境驱动因素。在这个角度来看,我讨论寄生虫infrachability的相互作用和他们的印记在空间和时间上的宿主免疫力。我进一步考虑从寄生虫群落动态反馈在更高层次的生物组织的疾病传播的个别主机,并强调系统生物学方法的承诺,以面粉甲虫为例,在野生种群的免疫变异的多重感染的作用进行研究。
A central challenge in the fields of evolutionary immunology and disease ecology is to understand the causes and consequences of natural variation in host susceptibility to infectious diseases. As hosts progress from birth to death in the wild, they are exposed to a wide variety of microorganisms that influence their physical condition, immune system maturation, and susceptibility to concurrent and future infection. Thus, multiple exposures to the same or different microbes can be important environmental drivers of host immunological variation and immune priming. In this perspective, I discuss parasite infracommunity interactions and their imprint on host immunity in space and time. I further consider feedbacks from parasite community dynamics within individual hosts on the transmission of disease at higher levels of biological organization and highlight the promise of systems biology approaches, using flour beetles as an example, for studying the role of multiple infections on immunological variation in wild populations.
