Extended-spectrum beta-lactamases (ESBL) are enzymes produced by E. coli like some gram-negative bacteria. The patients who are affected by ESBL producing bacteria facing a major problem and they may need different β-lactam antibiotics to treat the infection. But this extensive use of β-lactam antibiotics against ESBLs creating major public health threat. As an alternative currently many eco-friendly, non-toxic, low cost nanoparticles are synthesizing by biogenic way used as an alternative for the β-lactam antibiotics. In the present study silver nanoparticles (AgNPs) were synthesized using Ayurveda Toothpowder. The synthesized AgNPs were characterized using ultraviolet (UV)-visible (vis) spectroscopy, scanning electron microscopy (SEM), and transmission electron microscope (TEM) analysis and finally the antibacterial activity was performed against ESBL producing bacteria by well diffusion method. Antibacterial tests against ESBL producing E. coli cells using biogenic synthesized AgNPs showed significant antibacterial effect at low concentration of AgNPs. The results proved that the biogenic synthesised nanoparticles using Toothpowder extract would help to arrest ESBL producing bacteria and further detail study in the same filed will bring useful results against ESBL producing bacteria in future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
