Figure 1 – Mode of action of Mannan Oligosaccharides (MOS). In contrast, the MOS-coated pathogens are guided through the gastrointestinal tract, without the pathogens being able to exert its harmful effects. Consequently, the MOS-coated pathogens can no longer bind to the mannosylated surface carbohydrates on the intestinal cells. The MOS will bind to the adhesins on the pathogens. The adherence of these pathogens to the intestinal cells is inhibited in the presence of MOS in the gut lumen. coli and Clostridia contain adhesins that preferentially bind to mannosylated surface carbohydrates present on the outside of the host intestinal cells. However, major pathogens like Salmonella, E. Following invasion, the multiplication of the pathogen in the damaged host tissue leads to the infection.Īdhesins are different for different pathogens. Only once adhesion is successful, the pathogen starts excreting virulence factors that damage the host tissue, allowing for the subsequent invasion of the pathogen in the host. The pathogen does so by adhesins (cell surface receptors) present on its outside that bind to carbohydrates present on the surface of the intestinal cells ( Figure 1). The first step in the induction of an infection by a pathogenic gut bacterium, is the adherence of the pathogen to the host intestinal cells. The widely used yeast cell walls, commonly referred to as MOS, are an example of this. However, many routinely used feed ingredients used as antibiotic replacers are insoluble. ![]() Moreover, sick animals stop eating but keep on drinking. ![]() This in contrast to administration of feed ingredients via dry feed, where it takes time to order a new batch, to manufacture and deliver it before it finally can be offered to the animals. ![]()
