Brno Scientists Explore Bacteriocins as Potential Antibiotic Alternatives

Researchers at Masaryk University in Brno, Czech Republic, are investigating the potential of bacteriocins as an alternative to traditional antibiotics in the fight against antibiotic-resistant bacteria. Bacteriocins are naturally occurring antimicrobial peptides produced by certain bacteria that can inhibit the growth of other bacteria.

The research team, led by Dr. Gabriela Balíková Novotná from the Department of Experimental Biology, is focusing on the bacteriocins produced by lactic acid bacteria , which are commonly found in fermented foods such as yogurt and cheese. These bacteriocins have shown promising results in inhibiting the growth of various pathogenic bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE).

Why this matters: The rise of antibiotic-resistant bacteria poses a significant threat to global health, with an estimated 700,000 deaths annually attributed to antibiotic resistance. The development of alternative antimicrobial agents, such as bacteriocins, could help combat this growing problem and provide new treatment options for infections caused by antibiotic-resistant bacteria.

The Brno scientists are currently working on characterizing the bacteriocins produced by different strains of lactic acid bacteria and evaluating their effectiveness against a range of pathogenic bacteria . They are also investigating the mechanisms by which these bacteriocins inhibit bacterial growth and exploring ways to optimize their production and purification.

Dr. Balíková Novotná stated, "Our research aims to harness the natural antimicrobial properties of bacteriocins to develop new strategies for treating bacterial infections. By understanding how these peptides work and how we can effectively produce and deliver them, we hope to provide a viable alternative to traditional antibiotics."

The research team is collaborating with colleagues from the University of Chemistry and Technology in Prague and the University of Veterinary and Pharmaceutical Sciences in Brno to further advance their work on bacteriocins. They are also exploring the potential applications of bacteriocins in the food industry as natural preservatives and in the agricultural sector to reduce the use of antibiotics in livestock.

While the research is still in its early stages, the Brno scientists are optimistic about the potential of bacteriocins as a new class of antimicrobial agents. Dr. Balíková Novotná and her team are working to characterize the bacteriocins produced by lactic acid bacteria and evaluate their effectiveness against pathogenic bacteria. The collaboration with other Czech universities aims to advance the understanding and potential applications of bacteriocins in various fields, including medicine, food preservation, and agriculture.
