The role of Fusobacterium necrophorum and Bacteroides melaninogenicus in the aetiology of interdigital necrobacillosis in cattle

When cultures of known pathogenic strains of Fusobacterium necrophorum, isolated either from cattle or sheep were injected through the interdigital skin of cattle typical lesions of interdigital necrobacillosis were produced. The inclusion of Bacteroides melaninogenicus in the inoculum did not appear to contribute to the development of lesions.
