[Chemotypes of "Shigella flexneri" R mutants and related phage receptors. II. -- Localization of phage receptors (author's transl)].

Receptor sites for phages FP3, V, P1kcvir, H+, C21, T4, T3, T7 and 6SR have been investigated, by comparing the lytic activity of these phages on R mutants of strain F6 (F6R) and of various serotypes (FH) of Shigella flexneri with their inhibition by the lipopolysaccharides isolated from these mutants. The results suggest the following localizations for the receptor sites: phage FP3: lipid A-KDO; phage V: heptose or glucose; phage C21: heptose-glucose; phages H+, P1kcvir, T4 and T3: glucose; phage T7: glucose-galactose; phage 6SR: complete core structure.
