Changes in the response of black mollies Poecilia latipinna to infection with Ichthyophthirius multifiliis subsequent to single I. multifiliis infections were examined experimentally. Incomplete resistance to infection was established, the degree of which did not depend on the intensity of the initial infection. Resistance was maintained for longer periods, however, by those fish with higher initial levels of infection. Previous experience of infection by their hosts had a significant, though small, effect on the time for which trophozoites remained on the fish. The influence of these results on the population dynamics of the Ichthyophthirius-fish interaction is examined with the aid of simple mathematical models.
通过实验研究了黑摩利鱼（Poecilia latipinna）在单次感染多子小瓜虫（Ichthyophthirius multifiliis）后对再次感染多子小瓜虫的反应变化。建立了对感染的不完全抗性，其程度不取决于初始感染的强度。然而，初始感染水平较高的鱼能将抗性维持更长时间。宿主先前的感染经历对滋养体在鱼体上停留的时间有显著影响，尽管影响较小。借助简单的数学模型研究了这些结果对小瓜虫 - 鱼相互作用种群动态的影响。
