Green tea beneficial in destroying antibiotic-resistant bacteria

Aside from its benefits for weight loss, green tea is also well known for its antioxidant properties. According to recent research, green tea is also beneficial in getting rid of antibiotic-resistant bacteria. The study also said that antioxidant commonly found in green tea can terminate antibiotic-resistant bacteria.
The findings were published in the Journal of Medical Microbiology in which the researchers found that epigallocatechin (EGCG) can restore the activity of aztreonam, an antibiotic commonly used to treat infections caused by the bacterial pathogen -- Pseudomonas aeruginosa.
Researchers believe that in P. aeruginosa, EGCG may facilitate increased uptake of aztreonam by increasing permeability in the bacteria. Another potential mechanism is EGCG's interference with a biochemical pathway linked to antibiotic susceptibility.
"Antimicrobial resistance (AMR) is a serious threat to global public health. Without effective antibiotics, the success of medical treatments will be compromised. Natural products such as EGCG, used in combination with currently licenced antibiotics, maybe a way of improving their effectiveness and clinically useful lifespan," said lead author Dr Jonathan Betts, Senior Research Fellow in the School of Veterinary Medicine at the University of Surrey.
"The World Health Organisation has listed antibiotic-resistant Pseudomonas aeruginosa as a critical threat to human health. We have shown that we can successfully eliminate such threats with the use of natural products, in combination with antibiotics already in use," said Professor Roberto La Ragione, Head of the Department of Pathology and Infectious Diseases in the School of Veterinary Medicine at the University of Surrey.
