Belgian researchers have developed edible antibodies that can prevent gut bacterial infections. Normally antibodies need to be injected, but the antibodies developed by Dr. Vikram Virdi in the group of Dr. Nico Callewaert can instead be mixed with food and eaten. These antibodies are produced using yeast and have so far been shown to protect piglets from diarrhea-causing enterotoxigenic E. coli, which is a serious issue in pig farming. The edible antibody concept also has enormous potential for applications in human medicine, such as in preventing diarrheal disease outbreaks following natural disasters.
