Bacteriolysin
Definition
A specific antibody substance (or lytic antibody) produced by an organism as an immune response to the introduction of a bacterium, having the property of causing bacteriolysis in the presence of serum complement. Biochemically, bacteriolysins are part of the humoral defense mechanisms, acting as recognition markers that direct the cellular destruction complex toward pathogens.
