Heavy Metal and Petroleum Hydrocarbon Contaminants Promote Resistance and Biofilm Formation in <i>Vibrio</i> Species from Shellfish.

ABSTRACT: Shellfish are an essential component of the human diet, yet their safety is increasingly compromised by contamination with heavy metals, petroleum hydrocarbons, and pathogenic microorganisms, such as Vibrio, which pose significant health risks. This study examined shellfish samples from seafood markets, assessing the levels of heavy metals (e.g., cadmium, copper) and petroleum hydrocarbons, while isolating and identifying Vibrio species carried by the shellfish. The antimicrobial resistance profiles, resistance genes, and biofilm-forming capacities of these strains were further characterized. Results revealed significant seasonal fluctuations in heavy metal concentrations, with some samples exceeding regulatory limits, indicating potential health risks for long-term consumers
