Rectal swabs were collected from 297 patients within 48 h of admission to eight high-prevalence CP-CRE hospital departments, with follow-up swabs taken weekly for up to 4 weeks. Species identification, antimicrobial susceptibility testing, and genetic detection of carbapenemases were performed. The genetic relationship among isolates was assessed using ERIC-PCR, combined with epidemiological data, to investigate subsequent infections. <b>Results:</b> Fecal carriage of CP-CRE was detected in 15.5% (46/297) of patients- All carAntibiotics (Basel, Switzerland)109https://www.ebi.ac.uk/biostudies/studies/S-EPMC12837422biostudies-literatureRectal Colonization by Carbapenemase-Producing <i>Enterobacterales</i> in a Tertiary Care Hospital in Havana, Cuba.PMC12837422Aung MSRuiz-Garbajosa PGonzalez MKCanton RCarmona YGonzalez AHPerez DQBouza VTorres GEKobayashi NYu HRodriguez VRfalseRectal Colonization by Carbapenemase-Producing <i>Enterobacterales</i> in a Tertiary Care Hospital in Havana, Cuba.<b>Introduction:</b> Rectal colonization by carbapenemase-producing carbapenem-resistant <i>Enterobacterales</i> (CP-CRE) is a risk factor for subsequent infections, which are associated with high mortality rates. <b>Methods:</b> A cross-sectional study was conducted.
