原始语种摘要: Annual reports show that human infections caused by Vibrio spp. have nearly doubled over the past decade in the Virginia and Maryland waters of the Chesapeake Bay. Vibrio spp. are autochthonous to estuarine and coastal waters and follow a seasonal cycle attributed mainly to fluctuations in water temperature and salinity. This study presents the development of empirical algorithms for predicting the probability of Vibrio vulnificus and Vibrio parahaemolyticus likelihood and abundance in the upper Chesapeake Bay. To model likelihood of occurrence, a set of binary classification models was developed, employing a suite of geophysical predictor variables and statistical methods. Accuracy of results was ~ 68% at 0.40 prediction for V. vulnificus and ~70% at 0.60 prediction for V....
