In agreement with the established immunomodulating properties, administration of β-D-glucan led to enhanced T cell interferon-γ release in swine, which resulted in increased protection against porcine reproductive and respiratory syndrome virus and augmented resistance of pigs and newborn piglets against bacterial endotoxin whereas α-D-mannan component played role in stimulation of
the complement Mannan-Binding Lectin pathway, a crucial factor of protection due to innate immunity mechanisms and Bio-Mos® proved to be effective in weanling pigs against
the infections caused by Escherichia and Salmonella spp.
