A recent comparative study was conducted in collaboration with the Otago University Department of Microbiology. In this study the antibody specifically of a hyperimmune milk product was compared with that of a colostrum product derived from non-immunieed, pasture-fed New Zealand cows.
Specific antibody titres(concentration) to a panel of 19 of the same 22 pathogenic bacteria and yeast that were used as immunising antigens were determined by enzymes-linked immuoassay (ELISA). Three of the pathogens used as immunising antigens were not available due to regulatory imports restraints, Ministry of Agriculture and Fisheries (MAF). The early milk concentrate demonstrated a significantly higher IgG and IgG1 antibody titre against all of the antigens tested than the hyperimmune milk. In addition, the early milk concentrate was shown to stimulate the accumulation of immune cells in the peritoneum of Balb/c mice. The following specific antibodies to the following microbes were identified.
Pathogen Disease Condition
Bacillus cereus Food poisoning, Mastitis
Campylobacter jejuni Food Poisoning
Candida albicans Thrush - Yeast Infection
Clostridium difficile Food poisoning
Escherischia coli Commensal bacteria
