Green Tea Could Over Come on Super Bugs, Research shows

Researchers have discovered that one particular compound in green tea might bolster failing antibiotics and help them to kill bacteria more efficiently.

According to the Medical News Today, scientists, from the University Of Surrey School Of Veterinary Medicine in Guildford, United Kingdom, focused on the bacterium Pseudomonas aeruginosa. This bacterium can cause severe infections to the skin, the blood, and the respiratory and urinary tracts.

The bacteria are growing resistant to many antibiotics and are increasingly difficult to fight. Currently, doctors treat P. aeruginosa infections with a combination of antibiotics.

Green tea contains a compound known as epigallocatechin (EGCG). Medical researchers are interested in this polyphenol for several reasons. For instance, some studies have investigated whether it might treat inflammation and rheumatoid arthritis.

In the latest investigation, researchers combined EGCG with aztreonam, which is an antibiotic commonly used to fight P. aeruginosa. They found that the combination reduced the numbers of P. aeruginosa in laboratory cultures.

The research, which the scientists published in the Journal of Medical Microbiology, also investigated the interaction between EGCG and aztreonam in an animal model. Specifically, they used greater wax moth larvae, which scientists have found to be a useful model for studying antibiotics.

Once again, they found that when they combined EGCG with aztreonam, it was more effective than using the drug or EGCG alone.

The scientists believe that EGCG increases the permeability of the bacterium's membrane, allowing antibiotics to pass through more easily.
