Abstract
Abstract Novel microbicidal compositions are provided which find use as preservatives, disinfectants, antigens and the like. Particularly, cationic oligopeptides of up to about thirty-five amino acids are provided having amino acid sequences substantially comparable to the amino acid sequences of cationic oligopeptides produced by macrophage. A conserved framework structure is provided.
