Yan and his colleagues published a paper, "Major tdh+ Vibrio parahaemolyticus serotype changes temporally in the Bay of Bengal estuary of Bangladesh," today in the journal Infection, Genetics, and Evolution. This work was done in collaboration with Dr. Munirul Alam, senior author of the paper, from the International Centre for Diarrhoeal Disease Research, Bangladesh, as well as colleagues from the University of Dhaka and the National Institute of Infectious Diseases, Japan. Vibrio parahaemolyticus causes seafood-related gastroenteritis and shows a temporal serotypic shift from predominantly non-pandemic serotypes in 2006-2007 to predominantly pandemic serotypes in 2008, underscoring the need for routine environmental monitoring to prevent V. parahaemolyticus-related diseases.
