A study of the adsorption kinetics of T5+ and the tail fiber-less mutant hd-2 to lipopolysaccharides of various Escherichia coli strains demonstrated T5+ binding to the O-antigen of th O8 and O9 types. Incorporation of radioactive mannose into the phosphomannose isomerase-deficient strain E. coli F860 O9 pmi allowed the derivation of the number of O-antigens per cell required to increase T5 adsorption. With more than 500 O-antigen molecules, acceleration of T5+ adsorption was observed. The… CONTINUE READING
