Recent studies of surface waters have revealed large reservoirs of freshwater bacteria resistant to one or more antibiotics. Since these waterways, are multiple-use resources, including sources of drinking water, these discoveries are matters of public health interest. Concern over the spread of antibiotic resistant bacteria lead to the formation of the National Antimicrobial Resistance Monitoring System (NARMS) in the USA. However, this group does not monitor antimicrobial resistance in surface waters. Inspired by data collected from water samples from the Mud and Ohio Rivers, we have developed a dynamical model for bacteria in the river that includes both antibiotic resistant and non-antibiotic resistant bacteria. Because of the strong correlation between the land use along the river and levels of antibiotic resistant bacteria, we have included a function that describes the influx of bacteria from the shore. In this talk we will report the latest results of our study.
