Title: Modeling the environmental transmission of infectious diseases: Escherichia coli transmission in cattle

Dr. Cristina Lanzas

photo. Infectious diseases (e.g. influenza, enteric, foodborne and waterborne pathogens) can have environmental reservoirs and be transmitted by contact among individuals and between individuals and their associated environments. For diseases with environmental reservoirs, little is known about how the contact patterns between hosts and environment influence disease transmission. This REU project will study the spread of a zoonotic environmental-transmitted pathogen, Shiga-toxigenic Escherichia coli, in beef cattle populations. We will use animal movement datasets, data on pathogen survival in the environment, and mathematical models to study the role of the environment in transmission.
