چکیده انگلیسی
The influence of environmental parameters on the total and pathogenic Vibrio parahaemolyticus seasonal densities in American oysters (Crassostrea virginica) was evaluated for 1Â year. Harvesting site A yielded the highest mean densities of V. parahaemolyticus tlh+, tdh+/trhâ, tdhâ/trh+ and tdh+/trh+ during spring season at 2.57, 1.74, 0.36, and â0.40 log10Â MPN/g, respectively, and tdh+/orf8+ during winter season (0.90 log10Â MPN/g). V. parahaemolyticus tlh+ densities were associated to salinity (R2Â =Â 0.372, PÂ <Â 0.022), tdh+/trh+ to turbidity (R2Â =Â 0.597, PÂ <Â 0.035), and orf8+ to temperature, salinity, and pH (R2Â =Â 0.964, PÂ <Â 0.001). The exposure to salinity and temperature conditions during winter and spring seasons regulated the dynamics of V. parahaemolyticus harboring potentially pathogenic genotypes within the oyster. The adaptive response of V. parahaemolyticus to seasonal environmental changes may lead to an increase in survival and virulence, threatening the seafood safety and increasing the risk of illness.
