title: Phylogenetic analysis of Suid Herpesvirus 1 isolates from Argentina.
abstract: Argentinean Suid Herpesvirus 1 isolates were compared with reference strains and sequences available at GenBank and phylogenetically analyzed. A short fragment of the gE gene of the immunodominant epitopes was used for preliminary grouping of isolates by phylogenetic analysis. The analysis of the partial gC gene provided more precise genetic typing and segregation into the main genotypes I and II. Results confirmed that the Argentinean genotype I isolates predominate in our country. The topology of the partial gC gene was similar to that previously reported. The Argentinean type I isolates belonged to one cluster and grouped together with NIA-3 and American and Brazilian genotype I strains. However, the results obtained by the algorithms allow inferring that the Yamagata S-81 and Mer (genotype II) strains are grouped together.
