**Hyderabad, India – February 8, 2025** – The rise of antibiotic-resistant bacteria is a global health crisis, with 1.2 million deaths attributed to antimicrobial resistance in 2021 alone. A new study from the Centre for Cellular and Molecular Biology (CCMB) in Hyderabad sheds light on how bacteria survive antibiotic treatment, offering potential avenues for developing new therapies.
The research, published last year in PLOS Genetics, focuses on the bacterial cell wall, a unique structure targeted by many antibiotics. The cell wall’s peptidoglycan layer, made of sugar molecules and peptide crosslinks, is crucial for bacterial growth and division. Antibiotics like penicillin disrupt this process, weakening the cell wall and causing bacterial death.
However, bacteria have evolved resistance mechanisms, including producing enzymes that break down antibiotics or modifying the antibiotic’s target sites. Dr. Manjula Reddy’s team at CCMB has discovered that bacteria can compensate for the loss of one key enzyme involved in cell wall synthesis (endopeptidases) by overproducing another (lytic transglycosylases). This highlights the complex regulatory mechanisms bacteria use to survive.
By understanding these mechanisms, scientists can develop new strategies to combat antibiotic resistance. The CCMB research provides valuable insights into the intricate processes of bacterial cell division, paving the way for the development of novel antibiotics and treatments. The findings underscore the urgent need for continued research in this critical area of global health.
