مستخلص: | This study was conducted to monitor the densities of total and pathogenic Vibrio parahaemolyticusin 300 samples of nine shellfish species harvested from the coasts of the South Yellow Sea and the East China Sea (N 23° to 34°, E 116° to 124°), People's Republic of China, between May and October 2015. Total V. parahaemolyticusdensities were measured, and V. parahaemolyticusisolates were biochemically identified with probes for the thermostable direct hemolysin gene (tdh) and the thermostable direct hemolysin–related hemolysin gene (trh). We found that 202 of the 300 samples were positive for V. parahaemolyticusfrom all the sites: 58 of the 100 samples from the Fujian province, 71 of the 100 samples from the Zhejiang province, and 73 of the 100 samples from the Jiangsu province. In most (170) of the 300 samples, V. parahaemolyticusdensities were 0.3 to 10 most probable number (MPN)/g; five lots exceeded 110 MPN/g, and two lots were estimated at 110 MPN/g. Among the 202 V. parahaemolyticusstrains, only one was trhpositive. Densities of V. parahaemolyticusin these shellfish were temperature dependent, with highest densities in June and July. Among the nine mollusk species, V. parahaemolyticuswas most abundant in the agemaki clam (Sinonovacula constricta). The highest and lowest V. parahaemolyticusprevalences were found in oriental cyclina (Cyclina sinensis,93.8%) and mussels (Mytilus edulis,28.1%), respectively. Overall, although V. parahaemolyticusis widely distributed in marine environments, the density of V. parahaemolyticuswas low and the prevalence of the main virulence factor was very low in shellfish along the coasts of the South Yellow Sea and East China Sea, which is important from a public health perspective. Data presented here will be useful for correlational research and can be utilized for developing risk management plans that establish food safety guidelines for V. parahaemolyticusin Chinese shellfish. |
