Carbapenemase-producing Klebsiella pneumoniae isolates submitted to the Laboratory Network for Infection Surveillance System of the Canary Islands by Complejo Hospitalario Universitario Insular-Materno Infantil (Gran Canaria) during January 2023–March 2025 from study of emergence of NDM-14–producing K. pneumoniae sequence type 147 clone in Spain and outbreak in the Canary Islands. Numbers and percentages of NDM-14–producing K. pneumoniae isolates compared with all isolates are shown. Isolates were submitted if they fulfilled >1 of the following criteria: recovery from clinical samples associated with invasive infection (excluding colonization); recovery from clinical or environmental sources during outbreak or epidemic events; or detection of emerging pathogens requiring enhanced surveillance, including the NDM-14–producing K. pneumoniae isolates described. NDM, New Delhi metallo-β-lactamase.
