Egg Biotech , a Korean food biotech company, says it has made a breakthrough by launching immunoglobulin-enriched (IgY) eggs that fight against both enterotoxigenic e-coli and helicobacter pyroli. "This product takes egg nutrition to a new level. With a single egg, consumers can effectively fight against these two types of bacillus which are carried in a majority of humans," said company president Dr. Lee Nam-hyung.
