bla_VIM is a class B metallo-β-lactamase gene that confers high-level resistance to carbapenems and most β-lactams (via broad-spectrum hydrolysis) in Gram-negative bacteria like Pseudomonas aeruginosa and Enterobacteriaceae. Detection of bla_VIM signals a highly resistant organism (often hospital‐acquired) that will not respond to carbapenems; its presence typically prompts use of last-line agents and strict infection control measures (Vega et al. 2024, Nordmann et al. 2012).
