Abstract
The antibacterial effects of two lysozymes purified from rainbow trout kidney (type I and II) were tested on eight bacterial strains isolated from cases of clinical mastitis (staphylococci, streptococci and coliforms). Three other lytic agents were included in the experiments as controls: hen egg-white lysozyme, lysostaphin and mutanolysin. Proliferating bacteria were incubated with the various lytic agents, either in hearts infusion broth or in milk. The type II rainbow trout lysozyme decreased the number of live bacteria (colony forming units) of all the strains tested, but was most efficient against staphylococci. The other two lysozymes had little effect.Keywords
