Mechanisms of antibiotic resistance
Mechanisms of antibiotic resistance. Computer artwork showing 4 different ways in which bacteria can be resistant to an antibiotic. From top left: normal interaction between the antibiotic and its target site within the bacterium; alteration of the target site so the antibiotic is ineffective; active efflux of antibiotic so it passes out of the bacterium without having an effect; altered permeability of the bacterial cell wall prevents the antibiotic from entering the bacterium; inactivation of the antibiotic so that it breaks down within the bacterium before it can have an effect

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate mechanisms of antibiotic resistance in bacteria. Through computer artwork, four different ways in which bacteria can resist antibiotics are depicted, each represented in a distinct quadrant. In the top left quadrant, we witness the normal interaction between an antibiotic and its target site within a bacterium. This serves as a baseline for understanding how resistance can occur. Moving to the top right quadrant, we observe the alteration of the target site, rendering the antibiotic ineffective against the bacterium. The bottom left quadrant demonstrates active efflux of antibiotics from within the bacterium. This process allows antibiotics to pass out without having any effect on combating bacterial infections. Finally, in the bottom right quadrant, altered permeability of the bacterial cell wall prevents antibiotics from entering and exerting their therapeutic effects. Additionally, this artwork highlights another mechanism: inactivation of antibiotics within bacteria before they can take effect. The breakdown of these drugs occurs inside bacterial cells due to specific enzymes or other biochemical processes. Overall, this visually stunning illustration provides valuable insights into how bacteria develop resistance against antibiotics—a critical issue in modern medicine and public health efforts worldwide.
