It is found that the antibacterial components extracted from Persian onion can increase the efficacy of existing antibacterial drugs

Recently, a new study showed that a kind of onion can help to resist the antibiotic resistance of some tuberculosis The researchers believe that the antibacterial ingredients extracted from Persian onion can increase the efficacy of existing antibacterial drugs The relevant research team tested four different molecules of Persian onion The researchers found that there was a significant reduction of bacteria in MDR-TB, and the most promising candidate could inhibit the growth of isolated TB cells by more than 99.9% The compound extracted from Persian onion is disulfide One of the analogues of these compounds has antimicrobial activity, which can inhibit the growth of Mycobacterium tuberculosis at the concentration of 17 μ m (4
mg
L − 1); the other analogues (concentration range: 32-138
m [8-32
mg
L − 1) can inhibit Escherichia coli and multi drug resistant Staphylococcus aureus These compounds can also inhibit Klebsiella and Proteus The team believes that these compounds can be used with existing antimicrobial agents to fight TB resistant strains The researchers say they hope that molecules tested in the laboratory can combine with existing antibiotics to form new anti TB drugs (http://
