Superbugs vs Medicine: Can we stay ahead?

By: Emaan Ahmad

 

In an arms race, building a better weapon is only half the battle. The real challenge is building it before your opponent develops a defence.

 

Medicine has been fighting a similar battle for almost a century. In 1928, the discovery of penicillin changed medicine forever. For the first time, doctors had a powerful weapon against bacterial infections. But bacteria don't stay defeated for long.  It is almost like changing the lock on a door, only to find that the bacteria are already learning how to pick the new one. So if bacteria keep adapting, can medicine keep up?

 

You see, bacteria aren't just mindless little germs—they're living, adaptable organisms that can evolve, share genetic tricks, and find ways to survive in changing environments. And then superbugs are a bacterium that has developed resistance to one or more antibiotics. Unlike common perception, it isn't necessarily a ´stronger’ bacterium. It simply means an antibiotic that once killed or stopped it may no longer work. Resistance can arise through random genetic mutations or by bacteria acquiring resistance genes from other bacteria.

 

But how does a bacterium actually survive a drug designed to kill it? The answer lies in the remarkable ways bacteria can adapt. Resistance isn't one single trick; bacteria can protect themselves from antibiotics in several different ways. There are 3 mechanisms; Some bacteria can destroy the antibiotic itself. They produce enzymes that break down or modify the drug, preventing it from reaching its target. Others change the target. Many antibiotics work by binding to a specific bacterial molecule. If mutations alter that molecule, the antibiotic may no longer be able to bind effectively. And some bacteria simply throw the antibiotic back out. Special proteins called efflux pumps transport the drug out of the bacterial cell before it can cause enough damage.

 

The problem isn't that antibiotics suddenly become useless. It's that bacteria are constantly being selected for traits that allow them to survive them. 

It is crucial to understand why we should care about this fiasco. It is much bigger than 'some infections are harder to cure´. Although it may sound bizarre and technical, it will impact our everyday lives sooner than we think, especially the days we are sick. By sick I am not referring to a mundane fever but rather bigger things like surgery, organ transplantation, chemotherapy, and treatment of severe infections. WHO reported that around 1 in 6 laboratory-confirmed bacterial infections worldwide in 2023 were resistant to antibiotic treatment, showing that this isn't just a future problem.

 

On the brighter side, we are not completely doomed like Galielo yet. Because even though your everyday media diet may have convinced you that the scientists of today only ever research aesthetic concerns and other comparatively low-impact areas, they are in fact searching for drugs that can kill resistant bacteria, but discovering and developing new antibiotics is difficult. Doctors are also looking into more targeted therapy. Furthermore, researchers are investigating approaches including bacteriophages—viruses that infect bacteria—as well as other antimicrobial strategies. At the same time the problem stands: right now, as you read this article, bacteria are multiplying, mutating and exchanging genetic information. Some of them may emerge with the very traits that allow them to survive our antibiotics.

 

So, can we stay ahead? For now, yes—but only if medicine keeps adapting. New antibiotics, rapid diagnostic tests, vaccines, bacteriophages and other alternative treatments are giving scientists new ways to tackle resistant bacteria. At the same time, using antibiotics only when necessary and preventing infections in the first place can slow the spread of resistance.

 

Superbugs are not an unbeatable enemy, but they are an evolving one. We may never permanently win the fight against bacterial resistance; instead, staying ahead means continuously developing better ways to detect, prevent and treat infections before resistance catches up.
