虽然疾病和伤害对死亡率有明显的影响，但它们对行为的非致命性影响却鲜为人知。如果患病个体或多或少分散，这些行为效应可能会对种群水平的疾病动态产生重大影响。我们偶然地观察了斑带猫鼬（Mungos mungo）的传播事件，这些猫鼬要么是健康的，要么是由于受伤和/或一种新型结核杆菌mungi的临床症状而不健康的。我们发现患病和/或受伤的猫鼬比健康的个体更不可能分散，这表明疾病可能对分散产生重要影响，进而影响种群水平的疾病动态。
While disease and injury have obvious impacts on mortality, they can have less understood non-lethal impacts on behavior. These behavioral effects might have a significant consequences for population-level disease dynamics if diseased individuals are more or less likely to disperse. We opportunistically observed dispersal events in banded mongooses (Mungos mungo) that were either healthy or unhealthy due to injury and/or clinical signs of a novel tuberculosis pathogen, Mycobacterium mungi. We found that diseased and/or injured mongooses were significantly less likely to disperse than healthy individuals, suggesting that disease may have an important consequences for dispersal that could in turn affect population-level disease dynamics.
