Caption: Ocean and estuaries are a reservoir for V. cholerae, when we identified the organism in water samples from the Chesapeake Bay and off the coast of Maryland and Delaware. In the Chesapeake Bay, native V. cholerae populations fluctuate with the seasons. V. cholerae is more common in the northern part of the bay where salinity is low and when the weather is warmer. In fact, temperature and salinity combined predict the presence of V. cholerae with an accuracy of between 75.5 and 88.5 %. Furthermore, changes in salinity from year to year, due to the influx of freshwater from the Susquehanna River at the head of the Bay, may cause V. cholerae populations to fluctuate greatly.
