Extended-spectrum β-lactamase (ESβL) enzymes are produced by certain bacteria as a mechanism of resistance to β-lactam and extended-spectrumβ-lactam antibiotics. Previous investigations have confirmed that M. oleifera contains several bioactive compounds. This study aimed at evaluating the in vitro antibacterial effects ethanolic methanolic leaf extracts on extended-spectrum producing bacteria....
