[Experimental study of the antimicrobial effect of lysozyme in combination with antibiotics]

A synergistic effect of the antibacterial action of the lysozyme combination with various antibiotics against gram-positive and gram-negative microorganisms was found. The intensifying effect of lysozyme on its combination with antibiotics was more evident with respect to gram-positive microbes and less evident with respect to gram-negative organisms. The combinations os lysozyme with methicillin, lincomycin, oleandomycin or erythromycin proved to be most active against staphylococci. A high synergistic effect against streptococci was observed with the use of the lysozyme combination with benzylpenicillin, morphocycline, oleandomycin, ceporin or monomycin. The combination of lysozyme with macrolides had a maximum inhibitory effect on Coli bacteria.
