Viral sRNA Unlocks Phage Therapy Potential Against Drug-Resistant Bacteria Plaques formed by phage lambda on an E. coli culture are being counted by Adi Levkowitz. [Yosef Adest] As the number of antibiotic-resistant infections continues to rise, scientists are looking to bacteriophages (“phages”), viruses that infect bacteria, as an approach to tackling antibiotic resistance. A new study by researchers at the Hebrew University of Jerusalem has revealed how bacteriophages use a tiny piece of genetic material to hijack bacterial cells and make more copies of themselves. Focusing on infection of Escherichia coli by phage lambda, a bacteriophage that scientists have been studying for decades, research lead Sahar Melamed, PhD, and colleagues identified a virus-encoded small RNA molecule (sRNA) called phage replication enhancer sRNA (PreS) that acts like a hidden genetic “switch.” The team’s research indicated that this switch rewires bacterial genes to help the virus copy its DNA...
