Antimicrobial activity of branched oligo(hexamethyleneguanidine) hydrochloride on oral pathogens

Abstract

The present work is devoted to study of the antimicrobial activity of a new promising synthetic biocidal compound, branched oligohexamethylene guanidine hydrochloride. The studies were carried out using optional anaerobic bacteria Staphylococcus aureus and Klebsiella pneumoniae, as well as obligate anaerobic bacteria Actinomyces pyogenes, Actinomyces odontolyticus, Peptostreptococcus micros, Finegoldia magna, Veillonella parvula, Prevotella disiens and Fusobacterium nucleatum. It was shown that branched oligohexamethylene guanidine hydrochloride inhibits the growth of these bacteria, and facultative anaerobic bacteria are more sensitive to it. The assumptions about the mechanism of this activity of branched oligohexamethylene guanidine hydrochloride are made. The results of the study show that the substance can be recommended as a broad-spectrum biocide.
