Differences in phenotypic and genetic characteristics of Trueperella pyogenes detected in slaughtered cattle and pigs with septicemia

摘要

We investigated the hemolytic properties, biochemical properties, and possession of virulence factor genes of isolated from cattle and pigs withsepticemia. The porcine strains showed significantly stronger hemolyticity than the bovine strains. In addition, from cattle and pigs also differed inbiochemical properties. Virulence factor genes ( , , and ) were more prevalent in bovine strains, whereas other virulencefactor genes ( and ) were more prevalent in porcine strains. isolated from pig and cattle with septis cases in Japanesemeat inspection showed variability in biochemical and genetic properties. Differences were observed between porcine and bovine strain in term of the hemolytic strength and possession ofgenes for factors promoting adhesions which are considered pathogenic.
