This research provides a detailed classification and characterization of RNA viruses that infect bacteria. These viruses are particularly important for understanding basic principles of virus biology and have practical applications in environmental monitoring and medical treatments. Impacts on everyday life: • These viruses are used as indicators for monitoring water quality and safety • They serve as model systems for developing new antiviral strategies • They have potential applications in phage therapy to treat bacterial infections • They help us understand how viruses evolve and adapt to their hosts • Their presence in sewage and water systems makes them important for public health monitoring
