title: [The range of antigenic specificity of Bifidobacterium peptidoglycan].
abstract: The antigenic relationships of Bifidobacterium bifidum 1 peptidoglycans with different strains of this species (LVA-3, 791, GO-4), bifidobacteria of other species (B. adolescentis GO-13, B. breve 79-38, B. lactentis 79-41, B. longum GO-3) and bacteria of remote taxonomic groups (Streptococcus faecalis 6-3. Staphylococcus aureus COM 885, S. epidermidis COM 2124. Lactobacillus plantarum 1, Escherichia coli M-17) were studied on the basis of a highly sensitive test system permitting the registration of normal human antibodies to peptidoglycans. The level of cross reactions with staphylococci and streptococci correspond to intraspecific and antigenic affinity to L. plantarum and E. coli was considerably less pronounced. Copying a number of epitopes of bifidobacteria, S. aureus peptidoglycan seems to possess additional antigenic determinants which participate in the formation of immunological responsiveness in man.
