Glycoprotein C Gene of Caprine Herpesvirus Type 1 Contains Short Sequence Repeats (SSR)

Caprine herpesvirus 1 (CpHV-1) is responsible for vaginal and respiratory disease in goats. Infection by vaginal route is usually restricted to the genital tract whereas by nasal route the virus can spread throughout the body. In order to evaluate genomic diversity, nucleotide sequences of glycoprotein C (gC) of 13 (n.8 vaginal, n.5 nasal) CpHV-1 strains were analyzed. Amino acid (aa) sequences showed a variable number of short sequence repeats (SSR). Nucleotide and amino acid sequences of amplified products showed to contain a variable number of short sequence repeats among the examined strains. These results indicated that CpHV-1 isolates had genetic diversity in the gC gene regarding the number of SSR: 4 SSR of 60 bp in one strain, 2 SSR of 30 bp in seven strains and 1 SSR of 15 bp in three strains. Two strains had no SSR.
