[The characteristics of Corynebacterium diphtheriae adhesins]

The study of the properties of C. diphtheriae adhesins revealed the absence of their thermostability, which suggested the protein nature of these adhesins. C. diphtheriae also showed pronounced mannose-resistant hemagglutinating activity, as this activity remained unchanged even in the presence of d-mannose. The comparison of the adhesive activity of C. diphtheriae with their phage and corycine sensitivity revealed essential differences between these macroorganisms in the degree of their adhesiveness. The phage lysability and corycine sensitivity of C. diphtheriae strains, determined by the properties of their surface structure, correlated with the degree of their activity.
