Studies were carried out on the aspects of the epizootic process and the economic importance of acariasis in swine. It was established that the disease had widely spread. About 92 per cent of the pig-breeding farms proved infected, in which an average of 30.06 per cent of the animals showed symptoms of mange. The source of the infective agent were the diseased pigs. Infection was transmitted mainly through contact between normal and affected animals. The basic part in the epizootic process was played by sows and boars that were carriers of the parasites. Acariasis was shown to inflict heavy losses in pig farming. Acariasis-affected growing pigs gave 48.2 per cent lower weight gain as compared with intact animals of the same age.
对猪螨病的流行过程及经济重要性进行了研究。结果表明，该病已广泛传播。约92%的养猪场被证明受到感染，其中平均30.06%的动物表现出疥癣症状。传染源是患病猪。感染主要通过正常动物与患病动物之间的接触传播。在流行过程中，作为寄生虫携带者的母猪和公猪起了主要作用。螨病在养猪业中造成了重大损失。与同龄未感染的猪相比，感染螨病的生长猪体重增加降低了48.2%。
