Antibacterial activity of lysozyme-chitosan oligosaccharide conjugates (LYZOX) against Pseudomonas aeruginosa, Acinetobacter baumannii and Methicillin-resistant Staphylococcus aureus.

ABSTRACT: The recent emergence of antibiotic-resistant bacteria requires the development of new antibiotics or new agents capable of enhancing antibiotic activity. This study evaluated the antibacterial activity of lysozyme-chitosan oligosaccharide conjugates (LYZOX) against Pseudomonas aeruginosa, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA), which should resolve the problem of antibiotic-resistant bacteria. Bactericidal tests showed that LYZOX killed 50% more P. aeruginosa (NBRC 13275), A. baumannii and MRSA than the control treatment after 60 min. In addition, LYZOX was shown to inhibit the growth of P. aeruginosa (NBRC 13275 and PAO1), A. baumannii and MRSA better than its components. To elucidate the antibacterial mechanism of LYZOX, we performed cell membrane
