This paper introduces the long-term and continuing studies of the authors and their colleagues on several aspects of the host-parasite relations in cotton rat filariasis. Five methods are described for the calculation of the number of infective larvae of Litomosoides carinii transmitted to cotton rats and other laboratory animals by groups of Liponyssus bacoti mites. The relation between the calculated transmission intensities and the number of worms recovered from individual infected animals has been determined by each of the five methods. The accuracy and relevance of each method is discussed and one (method B) has been found to give a better correlation with worm recovery than the others. Some effects of infection with filariasis on the mites are described. The role of heavily infected mites in transmission is questioned and their influence on the calculation of transmission is discussed.
本文介绍了作者及其同事对棉鼠丝虫病宿主-寄生虫关系几个方面的长期持续研究。描述了五种计算巴氏厉螨群体向棉鼠和其他实验动物传播卡氏罗阿丝虫感染性幼虫数量的方法。通过这五种方法中的每一种，都确定了计算出的传播强度与从个体感染动物体内回收的虫数之间的关系。讨论了每种方法的准确性和相关性，发现其中一种方法（方法B）与虫体回收的相关性比其他方法更好。描述了丝虫感染对螨的一些影响。对重度感染螨在传播中的作用提出了质疑，并讨论了它们对传播计算的影响。
