Abstract

In this study, we determined some biochemical and immunogenic characteristics of the E. rhusiopathiae strain IVER1, which was isolated in Khanh Hoa in 2017. The result showed that the colony morphology and biochemical characteristics were similar to previous reports on E. rhusiopathiae in Vietnam and other countries. 16S rRNA nucleotide sequence analysis indicated the strain IVER1 was 100% similar to the E. rhusiopathiae strain ZZ12.3 isolated in China in 2012 (NCBI accession number: KC660995.1). Virulence of the strain IVER1 in pigs was equivalent to the national strain E.47. Immunogenicity of the strain IVER1 was identical to the immunogenic requirements for the inactivated swine erysipelas vaccine. Further research using the strain IVER1 for vaccine production is necessary to enhance disease prevention against the current E. rhusiopathiae strains.
