Pathogenicity of Fusobacterium necrophorum biovar C in mice by intraperitoneal and intraportal injections.
Three strains of Fusobacterium necrophorum biovar C were injected into mice intraperitoneally and intraportally. All the mice survived. In one mouse out of 15 mice injected intraperitoneally, a few focal abscesses were formed in the liver. The microorganisms were recovered from the liver abscess and the tissue of liver with abscess. No changes were observed in the organs of other 14 mice and no bacteria were recovered from them. In the 15 mice injected intraportally, no liver abscesses and no macroscopic changes in the organs were formed. However, the inoculated bacteria were recovered from the liver of four mice. The pathogenicity of F. necrophorum biovar C was weaker than that of other two biovars.
