dc.description.abstract | An investigation of the pathogenic characteristics of isolates of Vibrio parahaemolyticus was conducted by identifying the pathogenic tdh gene and then performing adherence and cytotoxicity assays. Genome sequences of the seafood isolates were analyzed using the Illumina HiSeq 2500 platform. The isolated strains were then mapped by comparing the genomes to the reference genome, and variations in the nucleotide sequences and amino acids were identified with the CLC Genomics Workbench program. The tdh gene was identified in four isolates of V. parahaemolyticus, of which three-SMFM201809-CPC7-3, SMFM201809-CF8-2, and SMFM201809-CF8-3-showed high cytotoxicity and differences in cell adhesion. These isolates were selected to identify virulence factors and genomic variations. All three isolates had the same virulence factors, such as adherence, secretion system, and toxin. In addition, amino acid variants were identified in the regions of type IV pilus, T3SS1 and T3SS1 secreted effectors, and thermolabile hemolysin. These results indicate that variations in amino acids found in regions related to adherence and cytotoxicity result in differences in adhesion efficiency and cytotoxicity; therefore, the isolates with these variations may cause more serious foodborne illness compared with other strains. HIGHLIGHTS Four Vibrio parahaemolyticus strains isolated from seafood had the toxic tdh gene. Three isolates with toxic genes had higher cytotoxicity than the standard strain. Genomic analyses revealed amino acid variations at regions related to the toxic gene. Amino acid variations make a difference in pathogenicity. | - |
