This serves as the body’s first line of defence against infectious organisms, while the acquired immunity develops antibodies through immunisation or infection, which is the body\'s second line of defence. 1,3/1,6 beta glucan provides a stimulus to activate cells of the innate immune system against infectious organisms.
