Green Tea Compound Could Help Fight Multidrug-Resistant Bacteria

Dr. Jonathan Betts from the University of Surrey and colleagues have found that the green-tea polyphenol epigallocatechin gallate (EGCG) can restore the activity of aztreonam, an antibiotic commonly used to treat infections caused by Pseudomonas aeruginosa, a Gram-negative pathogen that is intrinsically multidrug-resistant and frequently associated with healthcare-associated outbreaks. Epigallocatechin …
