Food Origins of Multi-Drug Resistant Hospital-Acquired Infections
This summer, the aim of my project is to investigate the origin of drug resistance in hospital acquired, multi-drug resistant bacteria. This project challenges the idea that human overuse of antibiotics is dominant in selecting for drug resistance in bacteria, and instead investigates the role of food as the primary source of new drug resistance for bacteria in our body. This is a particularly dangerous and has wide public health implications because of the ability for pathogenic bacteria in hospitals to rapidly acquire new drug resistances. Bacteria can harbor drug resistance through mobile genetic elements such as integrons and plasmids. This summer I will work on identifying such drug-resistance determinants on saprophytic sources and compare those sequences with drug resistant bacteria found in human blood stream infections.
