Dataset on antimicrobial resistance of Vibrio spp. isolates across Adriatic regions

The underlying hypothesis of this study was that Vibrio spp. isolates from different regions of the Adriatic Sea display distinct antimicrobial resistance patterns that reflect regional environmental conditions and anthropogenic pressures. To test this hypothesis, Vibrio isolates were collected from several Adriatic regions and phenotypically tested for antimicrobial susceptibility using standardized disk diffusion methods. The dataset demonstrates variability in resistance profiles among isolates from the northern, central, and southern Adriatic regions, including differences in the frequency of resistance to commonly used antibiotics. These patterns provide insight into regional trends in antimicrobial resistance and highlight the potential influence of local environmental and ecological factors. The data can be interpreted by comparing resistance profiles across regions and antibiotics, and can be reused for comparative analyses, meta-analyses, and broader One Health–oriented studies addressing antimicrobial resistance in marine environments and aquaculture-associated bacteria.
