Sunlight inactivation of enteric bacteria in coastal waters : cellular and community-level responses
Abstract/Contents
- Abstract
- Fecal indicator bacteria (FIB), E. coli and Enterococcus spp., are used to indicate fecal pollution and thus the presence of pathogens in recreational waters. FIB concentrations are used to assess the risk of illness associated with water contact. When the concentration of FIB exceeds set criteria, advisories are posted or beaches are closed. The effectiveness of using FIB concentrations to predict health risks, however, has been called into question by diel fluctuations in FIB concentrations. FIB concentrations in recreational waters decrease during sunlight hours and increase after sunset. While many studies have documented these fluctuations, knowledge gaps remain about sunlight inactivation mechanisms and the effect of sunlight on the entire microbial community in contaminated waters. Understanding how sunlight affects enteric bacteria in coastal waters is critical for predicting the health risks associated with water contact. This dissertation investigates the effect of sunlight on enteric bacteria in coastal waters at both the cellular and community levels.
