BackgroundCarbapenemase-producing Enterobacteriaceae (CPE) currently pose a significant global public health threat. KPC carbapenemases are highly endemic in Colombia mostly among Enterobacteriaceae. In Klebsiella pneumoniae (Kpn), horizontal transfer of genes encoding KPC and expansion of isolates belonging to clonal group (CG) 258 resulted in epidemic levels of carbapenemase-producing Kpn. We aimed to understand the dynamics of transmission of KPC-genes among CPE infecting and colonizing patients in an endemic area of Colombia.
