Dr. Udi Qimron of the Department of Clinical Microbiology and Immunology at Tel Aviv University's Sackler Faculty of Medicine has developed an efficient and cost-effective liquid solution that can help fight antibiotic-resistant bacteria and keep more patients safe from life-threatening infections.
The solution is based on specially designed bacteriophages — viruses that infect bacteria — that can alter the genetic make-up of antibiotic-resistant bacteria. "We have genetically engineered the bacteriophages so that once they infect the bacteria, they transfer a dominant gene that confers renewed sensitivity to certain antibiotics," explains Qimron.
The solution, recently detailed in the journal Applied and Environmental Microbiology, could be added to common antibacterial cleansers used on hospital surfaces, turning resistant bacteria into sensitive bacteria. It's easy to prepare, easy to apply, and non-toxic, Qimron notes. He estimates that one liter of the growth medium — the liquid in which the bacteriophages are grown — will cost just a few dollars.
The research was done in collaboration with PhD student Nir Friedman, lab technician Shahar Mor, and Dr. Rotem Edgar of the Ichilov Medical Center.
