American scientists report in the latest issue of "Natural Biotechnology" magazine that the GM cows they cultivated are effective against bovine mastitis caused by Staphylococcus aureus infection. If this technology enters the application stage, it can be a national dairy industry. Recover billions of dollars in economic losses. Researchers from the US Department of Agriculture report that they have implanted a gene similar to Staphylococcus aureus that mimics staphylococci in dairy cows in the research, leading to the production of a protein called "staphylococcus." The ability of transgenic cows to resist S. aureus infection has been greatly enhanced compared to that of ordinary cows. However, the researchers also pointed out that this GM cow can only resist bovine mastitis caused by Staphylococcus aureus infection, and it is not necessarily resistant to bovine mastitis caused by other bacteria. In addition, although genetic improvement is a very good technique, it cannot replace other measures to prevent bovine mastitis.
