Diversity, virulence, and antimicrobial resistance of the KPC-producing Klebsiella pneumoniae ST307 clone

2017

ABSTRACT : The global spread of Klebsiella pneumoniae producing Klebsiella pneumoniae carbapenemase (KPC) has been mainly associated with the dissemination of high-risk clones. In the last decade, hospital outbreaks involving KPC-producing K. pneumoniae have been predominantly attributed to isolates belonging to clonal group (CG) 258. However, results of recent epidemiological analysis indicate that KPC-producing sequence type (ST) 307, is emerging in different parts of the world and is a candidate to become a prevalent high-risk clone in the near future. Here we show that the ST307 genome encodes genetic features that may provide an advantage in adaptation to the hospital environment and t…

Description of Klebsiella spallanzanii sp. nov. and of Klebsiella pasteurii sp. nov

2019

AbstractKlebsiella oxytocacauses opportunistic human infections and post-antibiotic haemorrhagic diarrhoea. ThisEnterobacteriaceaespecies is genetically heterogeneous and is currently subdivided into seven phylogroups (Ko1 to Ko4, Ko6 to Ko8). Here we investigated the taxonomic status of phylogroups Ko3 and Ko4. Genomic sequence-based phylogenetic analyses demonstrate that Ko3 and Ko4 formed well-defined sequence clusters related to, but distinct from,Klebsiella michiganensis(Ko1),Klebsiella oxytoca(Ko2),K. huaxiensis(Ko8) andK. grimontii(Ko6). The average nucleotide identity of Ko3 and Ko4 were 90.7% withK. huaxiensisand 95.5% withK. grimontii, respectively. In addition, three strains ofK.…
