The role of various antigenic fractions of Bacteroides nodosus in eliciting protection against foot-rot in vaccinated sheep. 1978

D J Stewart

Sheep were vaccinated against foot-rot with various antigenic extracts of Bacteroides nodosus and challenged to assess their resistance. The protective immunogen was shown to be a heat-labile, high molecular weight surface antigen which was removed by ultrafiltration and was either identical to or closely associated with the fimbriae of the organism. Resistance appeared to be associated with the presence of a single high molecular precipitinogen distinct from the 0 antigen. Agglutinating antibodies to the surface antigen in immunised sheep were predominantly IgG1 whereas the 0 antigen induced predominantly IgM indirect haemagglutinating antibodies. Reactions at vaccination sites were less marked to the surface antigen than to the 0 antigen.

D005535	Foot Rot	A disease of the horny parts and of the adjacent soft structures of the feet of cattle, swine, and sheep. It is usually caused by Corynebacterium pyogenes or Bacteroides nodosus (see DICHELOBACTER NODOSUS). It is also known as interdigital necrobacillosis.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
