Borody, TJ, et al. Tunnel vision in the bowel. Center for Digestive Diseases (2001). Review of irritable bowel syndrome, including ulcerative colitis and Crohn's disease, and its etiology, including infective agents such as Shigella and Campylobacter. Infections of the gut are difficult to treat because no antimicrobial therapy is available that is effective against Clostridia spores. Only bovine colostrum has proven clinical efficacy in eradicating intestinal pathogens, such as rotavirus, and may help control the infections seen in chronic disorders such as irritable bowel syndrome due to the number of biologically active components in colostrum. The growth factors in colostrum help heal intestinal erosions and ulcerations. It also contains anti-inflammatory factors and is nutrient rich. Colostrum may be used alone or in combination with other anti-inflammatory and/or immune substances. Future research should focus on identifying immune strategies, novel delivery systems and identification of the bioactives in colostrum.
