In the environment, the application of phage therapy holds significant promise. For instance, phage therapy could be used to target and eliminate harmful bacteria in water sources, providing a valuable tool for ensuring water safety. This could be particularly beneficial in regions where water-borne diseases are common, aiding in the prevention of outbreaks and improving public health. Moreover, phage therapy could be deployed in wastewater treatment plants, offering a sustainable, low-impact method for treating antibiotic-resistant bacteria in these settings.
