National surveys of the virulence of field strains of myxoma virus were carried out in 1975 (128 virus strains) and in 1981 (123 strains), using the virulence testing method employed in a similar survey in 1962. Results showed that the virulence of field strains had increased between 1962 and 1975, and again between 1975 and 1981. The increases in virulence are thought to be a result of the development of resistance to myxomatosis in wild rabbit populations. The effects of the changes in virulence and resistance are discussed.
1975年(128个病毒株)和1981年(123个病毒株)开展了对黏液瘤病毒野外毒株毒力的全国性调查,采用的是1962年类似调查中所使用的毒力检测方法。结果显示,野外毒株的毒力在1962年至1975年间有所增加,在1975年至1981年间再次增加。毒力的增加被认为是野兔种群对黏液瘤病产生抗性的结果。文中讨论了毒力和抗性变化的影响。
