Rectal Carriage of Sequence Type 307 Klebsiella pneumoniae High‐Risk Clone Harboring Multiple Carbapenemase Genes in Community Hospitals Gauteng, South Africa

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Graphical presentation of rectal carriage of carbapenem‐resistant Klebsiella pneumoniae, highlighting ST307 high‐risk clone and IncX3 plasmid‐associated blaOXA‐181. This study highlights the threat linked to horizontal gene transfer of AMR genes by epidemic plasmids from Klebsiella pneumoniae high‐risk clones to other bacterial species.

Carbapenemase-producing Enterobacteriaceae in hospital wastewater:a reservoir that may be unrelated to clinical isolates [star] [PDF]

, 2016
Summary Background: Carbapenemase-producing Enterobacteriaceae (CPE) are an emerging infection control problem in hospitals worldwide. Identifying carriers can help reduce potential spread and infections.

Stony Coral Tissue Loss Disease Results in Persistent Microbial‐Level Disturbances on Coral Reef Ecosystems

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Reef microbiomes before the arrival of stony coral tissue loss disease (vulnerable stage) during the outbreak (epidemic) and after (endemic). Microbial diversity, network metrics, and functional potential varied among apparently healthy corals and the surrounding water and sediments across the stages.

Screening of Heavy Metals Tolerance among Beta-Lactamase Producing Bacteria from Contaminated Soil and Waste Water of Some Abattoirs in Adamawa State

UMYU Journal of Microbiology Research
Bacterial adaptability enables them to tolerate various stresses, including those from antibiotics and heavy metals.  This study aims to investigate the tolerance to heavy metals, as well as the production of beta-lactamase and metallo-beta-lactamase ...

The effect of imipenem and diffusible signaling factors on the secretion of outer membrane vesicles and associated Ax21 proteins in Stenotrophomonas maltophilia [PDF]

, 2015
Outer membrane vesicles (OMVs) are small nanoscale structures that are secreted by bacteria and that can carry nucleic acids, proteins, and small metabolites. They can mediate intracellular communication and play a role in virulence.

Approachable Synthetic Methodologies for Second-Generation β-Lactamase Inhibitors: A Review

Pharmaceuticals
Some antibiotics that are frequently employed are β-lactams. In light of the hydrolytic process of β-lactamase, found in Gram-negative bacteria, inhibitors of β-lactamase (BLIs) have been produced.

Role of the Zn\u3csub\u3e1\u3c/sub\u3e and Zn\u3csub\u3e2\u3c/sub\u3e Sites in Metallo-β-lactamase L1 [PDF]

, 2008
In an effort to probe the role of the Zn(II) sites in metallo-β-lactamase L1, mononuclear metal ion containing and heterobimetallic analogues of the enzyme were generated and characterized using kinetic and spectroscopic studies.

Emergence of New Delhi Metallo-β-Lactamase (NDM-5) in Klebsiella quasipneumoniae from Neonates in a Nigerian Hospital

Msphere, 2019
Carbapenem-resistant Klebsiella pneumoniae is of global health importance, yet there is a paucity of genome-based studies in Africa. Here we report fatal blood-borne NDM-5-producing K. quasipneumoniae subsp.
