We previously developed a multiplex PCR assay for the differentiation of serovar 1a, 1b, 2 and 5 strains of Erysipelothrix rhusiopathiae. In this study, we analyzed the serovar-defining chromosomal region of a serovar 2 swine isolate, which was PCR-positive for both serovars 1a and 2 by the multiplex PCR assay. Genetic analysis of the chromosomal region revealed that, as in serovar 1a strains, the ERH_1440 gene, which is usually truncated or missing in serovar 2 strains, was intact in this strain. This paper first shows an E. rhusiopathiae serovar 2 strain possessing an intact ERH_1440 gene and suggests that care may be needed when determining the serovar of such rare strains by PCR assay.
