Molecular characterisation of an outbreak of NDM-7-producing Klebsiella pneumoniae reveals ST11 clone expansion combined with interclonal plasmid dissemination

open access: yes, 2022
The aim of this study was to characterise a hospital outbreak of NDM-7-producing Klebsiella pneumoniae associated with the successful multidrug-resistant (MDR) high-risk clone ST11 between 2017 and 2019 in southern Spain.

A Single Amino Acid Substitution in CspA Increases Germination Sensitivity and Broadens Bile Salt Germinant Specificity in Clostridioides difficile Spores

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
In reservoir‐associated RT033 strains, we observe a natural rewiring of spore germination that lowers the activation threshold and broadens bile‐salt specificity, enabling germination at low germinant levels and in response to typically inhibitory bile‐salts common in animal hosts.

Transmission and evolution of OXA-48-producing Klebsiella pneumoniae ST11 in a single hospital in Taiwan

open access: yesJournal of Antimicrobial Chemotherapy, 2019
Abstract Objectives Epidemic spread of OXA-48-producing Klebsiella pneumoniae, mainly mediated by the transmission of a blaOXA-48-carrying plasmid, has threatened global health during the last decade. Since its introduction to Taiwan in 2013, OXA-48 has become the second most common carbapenemase.

Global evolutionary dynamics of virulence genes in ST11-KL47 carbapenem-resistant Klebsiella pneumoniae

open access: yesInternational Journal of Antimicrobial Agents
ST11-KL47 is a hypervirulent carbapenem-resistant Klebsiella pneumoniae (CRKP) that is highly prevalent in China and poses a major public health risk. To investigate the evolutionary dynamics of virulence genes in this subclone, we analysed 78 sequenced isolates obtained from a long-term study across 29 centres from 17 cities in China.
