A component and human breast milk similar transgenic goat milk will significantly reduce the young pigs intestine number of harmful bacteria. This breeding goats milk contains help babies in human milk from e. coli proteins, scientists hope to be able to improve the health of children in developing countries.
Human breast milk contains a variety of useful proteins, including natural mild antibacterial substances — lysozyme, helps the baby resistance of Escherichia coli and other pathogens. Stop breastfeeding, infant on resistance of harmful bacteria will drop sharply, causing diarrhoea diseases. Milk and goat's milk while supplementing part of nutrients, but the content is only human lysozyme in breast milk of a few thousandths, unable to afford the same protection.
In 1999, scientists breed transgenic goats, the mammary gland cell contains more protein lysozyme, etc. Since then the dish in the study found that through such means resulting transgenic goat milk to suppress biological tissue in the growth of bacteria. But it does live animals have the same effect, still need further validation.
To this end, the United States University of California at Davis geneticist James · Murray led the research team conducted an animal experiment. Researchers will have two weeks of young pigs are divided into two groups, the first group of young pigs fed genetically modified sheep milk, feeding on a second set of common goat milk, continuous 16 days. As a result, the ordinary sheep milk feeding swine intestinal Escherichia coli average quantity is feeding the transgenic goat milk young pigs from 100 to 4000 times, this proves that the transgenic goat milk can inhibit animal reproduction of coliform bacteria.
Related research results published in the August 4 edition of the transgenic research magazine. Murray said that he believed the transgenic goat milk to significantly improve children's resistance to Escherichia coli, since pig intestinal Escherichia coli type and the human intestinal tract of very similar. But in this kind of transgenic goat milk before officially take, you also need to do more research and experimentation.
According to data released by the World Health Organization, the world each year, around 2 million people died from bacterial infection caused by diarrhoea and dehydration, of which the proportion of children in developing countries.
