  • Viruses Help Scientists Battle Pathogenic Bacteria and Improve Water Supply
    Infectious bacteria received a taste of their own medicine from University of Missouri researchers who used viruses to infect and kill colonies of Pseudomonas aeruginosa, common disease-causing bacteria. The viruses, known as bacteriophages, could be used to efficiently ...More
