Complete genome sequences of Vibrio parahaemolyticus strains L2171 and L2181 associated with AHPND in Penaeus vannamei postlarvae by hybrid sequencing

Abstract:

Vibrio parahaemolyticus strains L2171 and L2181 were isolated from a Penaeus vannamei shrimp hatchery. Both strains carry the pVA plasmid harboring the PirAB genes encoding the binary PirAB toxins that cause the acute hepatopancreatic necrosis disease (AHPND) in cultured shrimp. The strains also harbor multidrug resistance (MDR) and a repertoire of virulence factor genes. Our goal was to determine their complete genome sequences and perform a comprehensive analysis of their genetic characteristics. Therefore, the genomes of two strains, which are highly virulent to shrimp were sequenced by Illumina and the PacBio platforms. These data contribute to a better understanding of V. parahaemolyticus and its role as a pathogen in commercially important species such as farmed shrimp, providing valuable insights for disease management in aquaculture.
