High genomic diversity of <i>Vibrio</i> parahaemolyticus from underexplored tropical northern Australia: a baseline for future surveillance.

ABSTRACT: Vibrio parahaemolyticus is an autochthonous marine bacterium that causes gastroenteritis after ingestion of raw or undercooked seafood and, less frequently, wound and tissue infections. Genomic information from northern Australia is scarce, and most sequences to date stem from foodborne outbreaks in southern states. We analysed 24 environmental and 5 clinical isolates (4 wound and 1 gastrointestinal case) collected in the wet-dry tropics from northern Australia and placed them alongside 48 representative public genomes. Core-genome phylogeny showed that the northern Australian strains sit within the broad VppAsia lineage and intermix with Asian and South American isolates, reflecting the limited geographic structuring in the marine environment. A gastrointestinal isolate (RDH3, ST-2
