[The antimicrobial effect of lysozyme on nasal mucosa]

We tested the effect of lysozyme on the nasal mucosa in a controlled double-blind in vivo study. The administration of non-pathogenic vaccine strains of living measles virus and of living Vivotif bacteria (attenuated Salmonella typhi) to 14 healthy subjects showed that lysozyme possesses a clear antimicrobial and antiviral effect.
