建立了莱姆病螺旋体伯氏疏螺旋体在北方梅花鹿、达米尼硬蜱及其脊椎动物宿主种群中传播的离散时间模型。该模型基于两年的扁虱生命周期，若虫在季节中出现的时间早于幼虫(不同世代)。硬蜱的螺旋体感染率(k；)是根据前一阶段的螺旋体感染率(k，)计算得出的：k；=k，+(&khihph)(1k，)，其中k=被感染的硬体的比例；kh=被感染的宿主个体的比例(宿主种h)；ih=寄主物种h的感染性(以受感染的宿主为食的未受感染的硬体)
A discrete-time model was developed of the spread of Lyme disease spirochetes, Borrelia burgdorferi, in populations of northern deer ticks, Ixodes dammini (Acari: Ixodidae), and their vertebrate hosts. The model was based on a 2-year tick life cycle, with nymphs occurring earlier in the season than larvae (of a different generation).' Ticks acquire spirochetes primarily from their small-mammal hosts?4 The prevalence of spirochetes among questing ticks ( k ; ) was calculated from spirochete prevalence in the previous stage (k , ) as follows: k; = k, + (&khihph) (1 k,), where k, = proportion of ticks infected; kh = proportion of host individuals infected (host species h ) ; ih = infectiousness of host species h (of uninfected ticks feeding on an infected host of
