Summary:
The article from The Hindu, dated October 28, 2025, discusses the counterintuitive effects of combining antibiotics. While it might seem logical to create a stronger antibiotic by mixing different types, research shows that certain combinations can be less effective than a single, appropriate antibiotic due to antagonism. This can happen because some antibiotics are bacteriostatic (stop growth) while others are bactericidal (kill bacteria), and the former can interfere with the latter. Moreover, any antibiotic use can contribute to the development of antibiotic resistance. A specific study highlighted in the article showed that combining ciprofloxacin (a bactericidal antibiotic) with tetracycline (a bacteriostatic antibiotic) actually increased the survival rate of E. coli bacteria.

The Hindu: Combining Antibiotics Can Backfire, Study Finds
October 28, 2025 — In a surprising development, researchers are warning that combining antibiotics, a strategy often considered to combat resistant bacteria, can sometimes worsen the problem. A new study published in Molecular Systems Biology reveals that certain antibiotic combinations can be less effective than using a single, carefully selected antibiotic.
The article in The Hindu highlights the issue of antagonism, where different antibiotics work against each other. Specifically, the piece points out that a bacteriostatic antibiotic, which halts bacterial growth, can impede the effectiveness of a bactericidal antibiotic, which actively kills bacteria.
“It might seem logical to create a more powerful weapon against infections by mixing antibiotics,” explains Ramya Kannan, health correspondent for The Hindu. “However, the reality is often more complex. Every antibiotic use puts pressure on bacteria to evolve and develop resistance. This means a poorly chosen combination can inadvertently contribute to the creation of ‘superbugs’ that are even harder to treat.”
The study cited in the article focused on E. coli bacteria. Researchers found that combining ciprofloxacin, which kills bacteria by damaging DNA, with tetracycline, which merely stops their growth, actually increased the survival rate of the bacteria. Tetracycline slowed down the bacteria’s metabolism, preventing ciprofloxacin from doing its job effectively.
This research underscores the importance of careful antibiotic selection based on the specific infection and the bacteria involved. Experts are urging doctors to avoid simply mixing antibiotics without a clear understanding of the potential consequences. The overuse of antibiotics is already a major concern and a global threat. The article suggests careful consideration of the type of infection and the types of antibiotic used is crucial in limiting the growing trend.
