Pilus-dependent B-morphotype bacteriophages isolated from various sour
ces were studied. The adsorption of phages on Pseudomonas aeruginosa p
ill was proven. Electron-microscopic examination of the morphology of
phages was carried out, and the adsorption properties were partially d
escribed. It was suggested that adsorption apparatuses of different pi
lus-dependent B-phages are alike with respect to structure and functio
n.
