Abstrakt:	Introduction: This study aimed to investigate the prevalence and the carbapenemase production ability of Klebsiella pneumoniae isolates from premature neonates' intestinal tracts in a Moroccan neonatal intensive care unit Methodology: Active rectal screening was performed among 339 preterm infants. The collected isolates were subjected to antibiotic susceptibility testing, phenotypic analysis of carbapenemase production, and molecular detection of carbapenemase genes. Results: Out of 293 K. pneumoniae isolates collected, 31.05% (91) were resistant to carbapenem and produced carbapenemase, resulting in a 22.12% rate of intestinal carriage. Among the carbapenem-resistant K. pneumoniae isolates, 40.65% (37) had co-harbored carbapenemase genes. All isolates contained the blaOXA-48 gene, and the blaNDM, blaVIM, and blaKPC genes were detected in 30.76%, 9.89%, and 2.19% of the isolates, respectively. Out of 30.76% of these isolates had both the blaOXA-48 and blaNDM genes, 8.79% had both blaOXA-48 and blaVIM, and only 2.20% had both blaOXA-48 and blaKPC genes. Furthermore, 88.57% of carbapenem-resistantK. pneumoniae isolates co-harboring carbapenemase genes were genetically related strains. Conclusions: This study revealed a high prevalence of intestinal carriage of carbapenem-resistant K. pneumoniae. Therefore, implementing effective screening and diagnostic measures, and focusing on antimicrobial stewardship are essential to preventing the spread of these resistant strains and minimizing the risk they pose to premature infants. Competing Interests: The authors have declared that no competing interests exist. (Copyright © 2023, Moussa et al.)
