Abstract

We studied the immune functions of IgY obtained from hens immunized with a mixture of formalin-treated pathogenic bacteria. The IgY inhibited the growth of Pseudomonas aeruginosa, the production of Staphylococcus aureus enterotoxin-A, and adhesion of Salmonella enteritidis to cultured human intestinal cells (Caco 2). The results indicated that IgY specific for plural bacteria has effects useful toward prevention of bacterial diseases.
