贝类中副溶血弧菌和沙门氏菌荧光定量PCR快速检测方法的建立
Rapid detection of Vibrio parahaemolyticus and Salmonella sp. in shell ifshes by Real-time quantitative PCR
摘要
Abstract
Rapid detection of pathogens is essential for rapid import inspection of live aquatic animals. In the paper, a real-time quantitative PCR assay was developed for rapid detection of V. parahaemolyticus and Salmonella sp. in shellfishes. PCR primers were designed targeting the species-specific gene gyrB of V. parahaemolyticus and the fimY gene of Salmonella sp. The specificity and repeatability of the method were also tested. The results showed that both V. parahaemolyticus strains and Salmonella sp. exhibited typical curves while the other negative control strains were not amplified, indicating the specificity of the assay. The standard curves showed good linearity at the range between 1.53×105 and 1.53×109 copies/μL for V. parahaemolyticus, and between 4.89×106 and 4.89×1010 copies/μL for Salmonella sp. The rapidness and reliability of the assay should be enough for the quick inspection of live imported shellfishes.关键词
