Data on fimbrial and afimbrial adhesion factors of bifidobacteria are presented. Pili-like structures, their composition and conditions of formation in various species of bifidobacteria are described. Several sugar-lytic enzymes serve as afimbrial adhesins in bifidobacteria. Transaldolase and enolase are detected in bifidobacteria on cells’ surface. Transaldolase ensures binding of bifidobacteria with mucin and their auto-aggregation. Surface enolase has an affinity to plasminogen, thus bifidobacteria obtain a surface-bound protein with proteolytic activity. Molecular structures giving bifidobacteria hydrophobic properties are described - surface lipoprotein Bop A and lipoteichoic acids.
