Restriction digestion patterns were used to determine differences in the DNA of various isolates of channel catfish virus (CCV). All viruses were different from each other and from the type strain of CCV. The differences in the digestion patterns were used to relate the viruses quantitatively as to sequence divergence between all pairs of viruses. A range of values from 104 nucleotide changes to 1,690 nucleotide changes/total DNA of CCV was found for the various pairs. A cladistic analysis produced a phylogenetic network relating the viruses by possible ancestory. This network indicated that some viruses were relatively more separated from other viruses that were clustered in the network. A phenetic analysis indicated that the viruses that were clustered in the network were also reasonably similar to one another.
限制性酶切图谱被用于确定斑点叉尾鮰病毒（CCV）不同分离株的DNA差异。所有病毒彼此不同，且与CCV的标准株也不同。酶切图谱的差异被用于定量关联所有病毒对之间的序列差异。不同病毒对的CCV总DNA中核苷酸变化范围为104个核苷酸变化至1690个核苷酸变化。系统发育分析产生了一个通过可能的祖先关系关联病毒的系统发育网络。该网络表明，一些病毒与网络中聚集的其他病毒相对更为分离。聚类分析表明，网络中聚集的病毒彼此之间也相当相似。
