blaVEB is a Class A ESBL found in Pseudomonas, Acinetobacter, and certain Enterobacterales, particularly in healthcare-associated infections. It hydrolyzes cephalosporins including third-generation drugs.
Detection of blaVEB in molecular susceptibility testing helps guide antibiotic selection in serious gram-negative infections, typically requiring carbapenems or newer agents. Sample type is typically a culture isolate or direct clinical specimen.
