Antimicrobial resistance (AMR) has become a major global health concern in recent years. It reduces the effectiveness of antibiotics and makes even common infections harder to treat. As resistant microorganisms continue to spread, they threaten medical progress, increase hospital stays, raise treatment costs, and can lead to higher death rates from diseases that were once easily manageable. One of the main reasons behind AMR is the misuse and overuse of antibiotics, which allows resistant bacteria to survive, adapt, and multiply. If this issue is not controlled in time, it could seriously weaken modern healthcare systems.

 

There are several important causes of antimicrobial resistance. Many people use antibiotics without proper prescriptions or take them for viral infections, where they have no effect. In addition, patients often do not complete their full course of antibiotics, which allows some bacteria to survive and become resistant. Overprescription by healthcare providers, especially of broad-spectrum antibiotics, also contributes to the problem. In many places, antibiotics are easily available without regulation in local pharmacies. The excessive use of antibiotics in agriculture and livestock for growth promotion further accelerates resistance. Poor hygiene, sanitation, and infection control practices also make it easier for resistant organisms to spread.

 

To address AMR at the local level, several practical steps can be taken. Public awareness needs to be increased so people understand the risks of self-medication and the importance of using antibiotics correctly. Strict rules should be enforced to ensure antibiotics are only sold with prescriptions. Hospitals and clinics should strengthen antibiotic stewardship programs to guide proper use. Improving sanitation, hygiene, and access to clean water can help reduce infection rates and limit the need for antibiotics. Better diagnostic facilities and disease surveillance systems are also important for accurate treatment. At the same time, more research should be encouraged to explore alternative antimicrobial sources.

 

In my BSc research, I focused on the potential of medicinal plants in fighting antimicrobial resistance. The results showed that extracts from common herbs and spices were effective against resistant pathogens such as Staphylococcus aureus, MRSA, and Pseudomonas aeruginosa. In particular, methanol and ethanol extracts produced clear zones of inhibition, indicating strong antimicrobial activity. These findings suggest that locally available medicinal plants could serve as affordable and sustainable alternatives or supplements to synthetic antibiotics. When combined with responsible antibiotic use and strong health policies, such approaches could play an important role in reducing antimicrobial resistance in the community.
