A joint study of the National Public Health Organization in Greece (NPHO) and the European Centre for Disease Prevention and Control (ECDC) conducted in 15 Greek hospitals in 2022 sheds light on the rapid spread of carbapenemase-producing, highly drug-resistant Klebsiella pneumoniae sequence type (ST) 39, following its initial documentation in a European-wide genomic survey in 2019.
The main aim of the genomic study described in this surveillance report was to determine the distribution of the highly drug-resistant clade of Klebsiella pneumoniae (sequence type (ST) 39 in Greek hospitals in 2022.
