Japanese scientists have discovered that an antibody specializes in "bad bacteria" in the intestines.
A Japanese research team recently discovered that an antibody specifically attacks "bad bacteria" in the intestines without affecting the role of "good bacteria" and is expected to be used for the prevention and treatment of intestinal diseases in the future.
There are a large number of bacteria in the intestines of humans and other animals. Some bacteria are harmful, such as Escherichia coli, Staphylococcus, etc., and many bacteria are beneficial to the human body, such as bifidobacteria and lactic acid bacteria. Hyperproliferation of "bad bacteria" can cause diseases such as enteritis in humans or animals.
A bulletin issued by the University of Nara Institute of Science and Technology on July 5 said that the school's biology professor, Xinzang Lizi and others, isolated a variety of IgA antibodies from the intestines of experimental mice and found one of the IgA antibodies codenamed W27. Can be combined with a variety of intestinal bacteria.
They fed the antibody to experimental mice with enteritis and found that the intestinal flora of the rats changed and the symptoms of intestinal inflammation were alleviated. The researchers also found that this antibody only attacks "bad bacteria" such as E. coli without impeding the function of beneficial bacteria such as lactic acid bacteria.
The results of this research are expected to improve the structure of the human intestinal flora. Drinking drugs containing this antibody in the future may help prevent and treat diseases such as enteritis. The relevant research results were published on the online edition of the monthly journal Nature Microbiology in the United Kingdom on July 4.
