The nucleic acid and structural proteins of infectious bursal disease virus serotype I (six isolates) were compared with those of serotype II (two isolates). Five of the serotype I isolates originated from chickens, whereas both serotype II isolates were from turkeys. The growth curves of representative isolates of both serotypes were similar, but the latent period and virus yield were different. The seven isolates tested had two segments of double-stranded genomic RNA. The RNA migration patterns of viruses belonging to each serotype were similar, but differences were noticed between the two serotypes. There were differences in the molecular weights of viral proteins (VP) 3 and 4 from the two serotypes, and serotype II isolates lacked VP-2.
将传染性法氏囊病病毒血清型I（六个分离株）的核酸和结构蛋白与血清型II（两个分离株）的进行了比较。血清型I的五个分离株源自鸡，而血清型II的两个分离株均来自火鸡。两种血清型代表性分离株的生长曲线相似，但潜伏期和病毒产量不同。所测试的七个分离株有两段双链基因组RNA。属于每种血清型的病毒的RNA迁移模式相似，但两种血清型之间存在差异。两种血清型的病毒蛋白（VP）3和4的分子量存在差异，并且血清型II分离株缺乏VP-2。
