Risk Factors for Colonization of E. coli in Atlantic Bottlenose Dolphins (Tursiops truncatus) in the Indian River Lagoon, Florida

摘要: Opportunistic pathogens related to degradation in water quality are of concern both wildlife and public health. The objective this study was identify spatial, temporal, environmental risk factors for E. coli colonization among Atlantic bottlenose dolphins (Tursiops truncatus) inhabiting the Indian River Lagoon (IRL), FL between 2003 2007. Age, gender, capture location, coastal human population density, proximity sewage treatment plants, number septic tanks, cumulative precipitation 48 hrs 30 days prior capture, salinity, temperature were analyzed as potential factors. Highest rates occurred northern segments IRL. highest youngest individuals, counties with rainfall systems during year capture. prevalence 2004, a which multiple hurricanes hit coast Florida. Septic combination weather-related events suggest possible pathway introduction fecal coliforms into estuarine ecosystems. ability bacteria act primary or cause opportunistic infections adds importance these findings.
