Objective: To clone, sequence and analyze genome segment 1 (S1) of new isolated reovirus strains.
目的：克隆测序新分离呼肠病毒的S1全长基因组片段，并对其进行序列分析。
Reovirus includes 3 serotypes. Homology of proteins encoded by S1 genome segment was less than 26% between serotypes, while that of viral proteins encoded by other 9 segments was all more than 86%.
呼肠病毒共有3个血清型，不同型之间S1片段编码蛋白的同源性小于26%，其它9个片段编码蛋白的同源性都在86%以上。
