Abstract

SYNOPSIS The galactosephilic and mannosephilic hemagglutinins of Pseudomonas aeruginosa adsorbed onto Euglena gracilis, Chlamydomonas reinhardi, and Tetrahymena pyriformis. Furthermore, peroxidase binding to the 3 protozoan species was shown to be mediated by these lectins. Binding of Pseudomonas lectins to E. gracilis and C. reinhardi caused their specific agglutination, whereas no agglutination was observed with T. pyriformis, even after treatment by papain or by NaF. Added to the culture medium, the Pseudomonas hemagglutinins stimulated growth of E. gracilis and T. pyriformis due to their binding to these protozoa: this effect was partly inhibited by the specific sugar.
