Isolation and screening of Vibrio parahaemolyticus strains to cause acute hepatopancreatic necrosis disease in white-leg shrimps cultured in Phong Dien, Thua Thien Hue using 16S rRNA marker
Summary: In recent years, acute hepatopancreatic necrosis disease (AHPND) in Litopenaeus vannamei has been one of the diseases that cause serious damage to the shrimp farming industry in Phong Dien district, Thua Thien Hue province. The disease causes mass death of shrimps at the age of 20–45 days (mortality rate up to 100%) in both Penaeus monodon and Litopenaeus vannamei. The agent causing AHPND is Vibrio spp. strains containing two PirA and PirB toxin genes on the same plasmid. Using the PCR technique with two specific primers, we identified two strains of Vibrio parahaemolyticus, namely K5 and K21 bearing PirA and PirB toxin genes from five isolates. The results of the sequence analysis of 16S rRNA gene confirmed that Vibrio sp. K5 and Vibrio sp. K21 belong to Vibrio parahaemolyticus.
