Researchers on the Indian Institute of Know-how (IIT) Roorkee have made a major discovery concerning how Acinetobacter baumannii, one of the vital difficult drug-resistant pathogens identified for inflicting persistent and continual infections in hospitals, withstands meropenem, a last-resort antibiotic.
The analysis staff is led by Prof. Ranjana Pathania and consists of Arsalan Hussain, Timsy Bhando, Ananth Casius, and Rinki Gupta. The staff discovered that persister cells of A. baumannii alter their membrane properties and vitality metabolism, rising their antibiotic tolerance, as knowledgeable by IIT Roorkee.

Subsequently, researchers explored the potential of protected, naturally derived compounds to counteract bacterial persistence.
As per the examine, thymol, a plant-based compound generally present in thyme, might assist weaken the persisters. Preliminary findings point out that thymol, together with meropenem, enhances the antibiotic’s exercise, providing a potential strategy for tackling persistent infections.
Prof. Ranjana Pathania, the lead researcher, identified that the flexibility of thymol to disrupt bacterial persistence and improve the efficacy of present antibiotics presents a promising avenue in addressing antimicrobial resistance.
“By concentrating on persister cells, we might find a way to enhance therapy outcomes for continual and recurrent infections,” mentioned Prof. Pathania.

Moreover, it was additionally discovered after extra experiments that thymol works by a number of mechanisms to weaken persister cells. It disrupts bacterial vitality manufacturing as effectively as damages the protecting outer membrane, rising the micro organism’s vulnerability.
Apart from, Thymol additionally generates reactive oxygen species (ROS), which stress and weaken the micro organism, and inhibits bacterial efflux pumps, probably enhancing the effectiveness of meropenem.
The examine, nonetheless, maintains that further analysis and medical validation are required to assess thymol’s potential in real-world therapeutic purposes.

Highlighting the significance of the analysis, IIT Roorkee Director Prof. Ok.Ok. Pant mentioned “Antimicrobial resistance is a vital international problem. This examine by IIT Roorkee researchers demonstrates how progressive approaches, together with pure compounds, may contribute to overcoming persistent infections. It displays our institute’s dedication to analysis that addresses urgent healthcare challenges.”
Notably, the findings of the analysis have been printed within the Antimicrobial Brokers and Chemotherapy Journal of the American Society for Microbiology, and the following section will concentrate on refining the thymol-meropenem mixture and evaluating its potential by additional research.
