Environmental parameters influence on the dynamics of total and pathogenic Vibrio parahaemolyticus densities in Crassostrea virginica harvested from Mexico’s Gulf coast

•V. parahaemolyticus densities in oysters were isolated in spring and winter seasons.•Pathogenic genes abundances varied with environmental parameters seasonal changes.•Water temperature modulated V. parahaemolyticus abundance during reduced salinities.•V. parahaemolyticus with potentially pathogeni...
