AmpC β-lactamases are class C enzymes under the Ambler classification scheme, containing serine residues at their active site for catalysis. Mechanisms of AmpC β-lactamase resistance can be divided into 3 categories: (1) inducible resistance via chromosomally encoded ampC genes (eg, Enterobacter cloacae, Serratia marcescens, Citrobacter freundii, Pseudomonas aeruginosa, etc.), (2) noninducible chromosomal resistance due to promoter and/or attenuator mutations (eg, Escherichia coli, Shigella spec

Pseudomonas aeruginosa carrying an inducible AmpC gene that is usually silent, but when imipenem is present it acts as a strong inducer, triggering overproduction of AmpC, which results in a D-zone effect toward ceftazidime and piperacillin–tazobactam, making these antibiotics appear susceptible initially but prone to failure after induction Cefepime remains susceptible because it is structurally stable against AmpC and less affected by induction. This AST pattern indicates inducible AmpC produc

Você já caiu na armadilha do AmpC? No antibiograma parece tudo sensível, mas na prática o antibiótico falha. Bactérias com gene AmpC podem induzir produção de betalactamase durante o tratamento, perder sensibilidade e levar à falha terapêutica mesmo com um antibiótico que parecia adequado, como a ceftriaxona. Entender AmpC não é detalhe de microbiologia. É decisão clínica que muda desfecho, evita erro de escolha empírica e protege o paciente de evolução desfavorável. 👉 Ficou na dúvida se aquele
