Dr. Smith’s research interests include the gut as a source of infection in infants. The development of the normal intestinal bacteria or flora is frequently altered in infants that are hospitalized in the newborn period particularly premature infants. This leads to systemic infections and in some cases the development of necrotizing enterocolitis. Necrotizing enterocolitis is particularly dangerous disease which can lead to significant intestinal loss, sepsis, and possible death. Dr. Smith and his team have working to better understand how alteration in the intestinal flora and other factors can be altered to prevent or lessen the severity of necrotizing enterocolitis.
