The diabetogenic variant PV2 of encephalomyocarditis virus was cloned, and three recombinants differing in their 5' poly(C) tracts were analyzed. It is shown that the poly(C) region is not essential for infectivity in mice but does influence the virus load and degree of pathological lesions within the Langerhans' islets but not in the myocardium.
克隆了脑心肌炎病毒的致糖尿病变异体PV2,并分析了三种在其5'聚(C)序列上不同的重组体。结果表明,聚(C)区域对小鼠的感染性不是必需的,但确实会影响朗格汉斯胰岛内的病毒载量和病理损伤程度,而对心肌则无影响。
