Wild berry extract can solve the problem of bacterial resistance!

Berry extracts, which have been used for centuries in South America, are believed to be effective against antibiotic resistance The researchers believe that the berry, called the black pepper tree, contains a chemical that can effectively kill MRSA MRSA is called methicillin resistant Staphylococcus aureus, which is a common bacteria that can cause skin tissue damage However, severe infection can lead to a fatal risk 11000 people die each year in the United States However, researchers from emoin University found that the fruit extract of Brazil black pepper tree can block the process of bacterial infection in mice by blocking the expression of a gene inside the bacteria This extract actually contains 27 kinds of chemicals When the mice were inoculated with MRSA, the treatment of this extract could prevent the formation of wounds Compared with this, the control group mice had obvious infected wounds According to the researchers, the drug does not directly kill bacteria, but by inhibiting the expression of a class of molecular related genes responsible for the communication between individuals in bacteria, that is, "cluster sensing" Although the extract can inhibit the expression of cluster sensing molecules, it will not have a negative impact on the normal tissues of mice At present, the antibacterial effect of the extract is only verified at the level of mice, and the researchers hope that the discovery can be further applied to the anti infection treatment of human patients Previously, researchers found that leaf extracts from chestnut trees from Europe also contained molecules that attenuated bacterial quorum sensing signals All in all, these drugs can provide a new treatment for drug-resistant bacterial infection.
