Abstract excerpt

BACKGROUND: The prevalence of oxacillinase (OXA)-244-producing Enterobacterales is increasing in Europe, but their detection on screening media is limited. We assessed the proportion of OXA-244 carriage among carbapenemase-producing Enterobacterales (CPE) isolates, and specifically among OXA-48-like producers, at our hospital, addressing the challenges posed by conventional detection methods. METHODS: Patients...
