Pathogenicity and Genomic Characterization of <i>Vibrio parahaemolyticus</i> VSP1: A Pathogen Linked to Enteritis Outbreak in Shrimp (<i>Penaeus vannamei</i>).

ABSTRACT: Enteritis is a common and recurrent disease in shrimp aquaculture, causing significant economic losses and management challenges. However, its specific causative pathogen remains unclear. Here, a pathogen strain, Vibrio parahaemolyticus VSP1, was directly isolated from shrimp with enteritis, and its pathogenicity and genomic characteristics were analyzed. Diseased shrimp exhibited lethargy, empty gut, hepatopancreatic atrophy, and severe intestinal damage. The gut bacterial community of diseased shrimp differed significantly from healthy shrimp (PERMANOVA, p < 0.05), with a 129% increase in Vibrio relative abundance. Nine Vibrio operational taxonomic units (OTUs) were enriched in diseased shrimp, and the dominant OTU1 shared 100% 16S rRNA identity with VSP1. VSP
