Bacteriotropin
Definition
A specific antibody substance (or modified opsonin) present in immune serum, capable of binding to the surface of bacteria to modify their cell wall, making them far more susceptible to phagocytosis by leukocytes. Biochemically, bacteriotropins act as marking and activating elements of the cellular defense system, enhancing the capacity of macrophages to recognize and destroy pathogens.
