Genotypic Characterization of Infectious Spleen and Kidney Necrosis Virus (ISKNV) in Southeast Asian Aquaculture
Table 5
Amino acid similarity for gene-by-gene comparison within the predicted ORFs in the samples from the present study and reference samples from similar genotypes. Data are the sum of genes within the categories for percentage similarity compared to angelfish iridovirus AFIV-16 (ISKNV genotype, MK689685), pompano iridovirus isolate PIV 2014a (RSIV genotype clade 1, MK098186 PIV 2014), and RSIV isolate KagYT96 (RSIV genotype clade 2, MK689686).
