Abstract: Pseudomonas aeruginosa is one of the major bacteria causing acute infections. ?-Lactamase production is the principal defense mechanism in gram-negative bacteria. The aim of our study was to evaluate the antibacterial activity of Methanolic Extracts of Green and Black Teas on P. aeruginosa Extended Spectrum-?-Lactamases (ESBLs) production. This research was carried out on burn wounds of 245 hospitalized patients in Kerman, Iran. P. aeruginosa ESBLs and MBL producing strains were detected by Combination Disk Diffusion Test (CDDT) and Epsilometer test (E-test) strips, respectively.
