Bitzan, MM, et al. Inhibition of Helicobacter pylori and Helicobacter mustelae binding to lipid receptors by bovine colostrum. Journal of Infectious Disease 177(4):955-961 (1998). H. pylori and H. mustelae (a gastric pathogen of ferrets) are both bound by lipid receptors (phosphatidylethanolamine, gangliotetraosylceramide and gangliotriaosyl-ceramide) in the gut, allowing them to carry out their pathogenic activities. Bovine colostrum, however, was shown to prevent binding of the pathogens to these lipid receptors even though there was no detectable anti-H. pylori antibody activity in the colostrum.

Casswall, TH, et al. Bovine anti-Helicobacter pylori antibodies for oral immunotherapy. Scandinavian Journal of Gastroenterology 37(12):1380-1385 (2002). Bovine colostrum with high titers against H. pylori was given to H. pylori infected mice. Comparison of treated mice with control mice showed a 50-66% cure rate for H. pylori infection in treated mice. Binding studies also showed that the colostrum prevented binding of the H. pylori.
da Costa, RS, et al. Characterization of iron, copper and zinc levels in the colostrum of mothers of term and pre-term infants before and after pasteurization. International Journal of Food Science and Nutrition 54(2):111-117 (2003). Milk samples were collected from mothers from day 1 to day 7 postpartum. Milk that was pasteurized showed some diminution of zinc, copper and iron levels, but not to a significant degree. Sufficient levels remained in the pasteurized milk to supply the needs of the new-born infants.

Ellison, RT III, Giehl, TJ. Killing of gram-negative bacteria by lactoferrin and lysozyme. Journal of Clinical Investigation 88(4):1080-1091 (1991). Lactoferrin and lysozyme act together to kill gram-negative bacteria, such as Vibrio cholerae (cholera), Salmonella typhimurium (food poisoning) and Eschericia coli. The lactoferrin attaches to and destroys the cell wall of the bacteria, allowing the lysozyme to enter and lyse (burst) the organisms.

These are complex sugars which compete for binding sites in the GI tract with pathogens.

Korhonen, H, et al. Milk immunoglobulins and complement factors. British Journal of Nutrition 84(Suppl.1):S75-S80 (2000). Bovine colostrum contains three main classes of immunoglobulin IgG (IgG1 75% and IgG2), IgM and IgA, plus hemolytic and bactericidal complement. Complement is a complex group of proteins which act in concert with antibodies to inactivate and/or kill pathogens.
Korhonen, H, et al. Bactericidal effect of bovine normal and immune serum, colostrum and milk against Helicobacter pylori. Journal of Applied Bacteriology 78(6):655-662 (1995). Helicobacter pylori is a major cause of gastritis and ulcers in humans. Serum and colostrum from non-immunized Friesian cows were found to be highly bactericidal against H. pylori. Post-colostral milk did not show any bactericidal effect against H. pylori.
Lilius, EM, Marnila, P. The role of colostral antibodies in prevention of microbial infections. Current Opinion in Infectious Diseases 14(3): 295-300 (2001). Colostrum offers passive protection against a variety of microbial pathogens in the form of specific immunoglobulin A, G and M antibodies. It is especially effective in the prevention of various gastroenteric infections.

Ogra, PL, et al. Colostrum derived immunity and maternal neonatal interaction. Annals of the New York Academy of Sciences 409: 82-92 (1983). Peyer's patches are found throughout the intestinal tract, and groups of similar immunoactive cells are found in the bronchial mucosa. Both the intestinal and bronchial immunoactive cell groups respond to allergens, antigens and pathogens by neutralizing or destroying them. In newborns, these special cell groups are not immediately operative but protection is provided by a variety of immune factors from the mother's colostrum. Antibodies found in colostrum protect against Eschericia coli, Salmonella, Shigella, Vibrio cholera, Bacteriodes fragilis, Streptococcus pneumoniae, Bordtella pertussis, Clostridium diphtheria, Clostridium tetani, Streptococcus mutans and Candida albicans.

Wada, T, et al. The therapeutic effect of bovine lactoferrin in the host infected with Helicobacter pylori. Scandinavian Journal of Gastroenterology 34(3):238-243 (1999). Mice infected with H. pylori were given a daily dose of bovine lactoferrin for 2-4 weeks. Their intestines were then examined for bacterial content. Numbers of H. pylori were reduced to 10% of pre-lactoferrin levels and greatly decreased the numbers of H. pylori bound to the intestinal wall. Serum antibody titer to H. pylori were reduced to practically zero, indicating that the immune response of the host was no longer recognizing H. pylori infection. Therefore it was deduced that lactoferrin has a direct antibacterial effect on H. pylori infection and prevents binding of the pathogen to the intestinal lining.
