摘要: The initial stages of a disease outbreak can determine the magnitude ensuing epidemic. Though rarely tested in unison, two factors with important consequences for transmission dynamics infectious agents are collective traits susceptible population and individual index case (i.e. ‘patient zero’). Here, we test whether personality composition social group explain horizontal cuticular bacteria using spider Stegodyphus dumicola . We exposed focal spiders known behavioural phenotypes GFP-transformed bacterium ( Pantoea sp.) placed them groups 10 individuals those no experience this bacterium). measured bacterial to composed either all shy spiders, 10% bold or 40% spiders. found that colonies experienced over twice incidence compared just after only 24 h interaction. Colonies an intermediate degree transmission. Interestingly, did not detect effect on These data suggest phenotypic have greater influence early events than case.
