Table 3.

Sequence analyses of 3abc genes FIPV samples. Deletions affecting two genes are listed in both columns. Numbering of the nucleotides refers to complete ORF3, beginning with the first nucleotide of gene 3a and ending with the last nucleotide of gene 3c. The impact of mutations on putative translation products is given as number of encoded amino acids. Alterations of 3a (70 aa), 3b (73 aa) or 3c (237 aa) are indicated by grey colour.
