Abstract
A NUMBER of polypeptides composed of various basic amino-acids have been prepared by Katchalski et al., and it had also been stated that agglutination of Grain-positive and Gram-negative bacteria was caused by these polypeptides, and bacteriostatic or bactericidal activity was observed depending on their concentration1. Stahmann and his co-workers2 have reported that the multiplication of some viruses was restrained by poly-L-lysine.
