Genes encoding OXA-48-like carbapenem-hydrolyzing enzymes are often located on plasmids and are abundant among carbapenemase-producing (CPE) worldwide. After a large plasmid-mediated outbreak in 2011, routine screening of patients at risk of CPE carriage on admission and every 7 days during hospitalization was implemented in a large hospital in the Netherlands. The objective of this study was to investigate the dynamics of the hospitals' 2011 outbreak-associated plasmid among CPE collected from 2011 to 2021.

The NRCS-A strain has emerged as a global cause of late-onset sepsis associated with outbreaks in neonatal intensive care units (NICUs) whose transmission is incompletely understood. Demographic and clinical data for 45 neonates with and 90 with other coagulase-negative staphylococci (CoNS) isolated from sterile sites were reviewed, and clinical significance was determined. isolated from 27 neonates at 2 hospitals between 2017 and 2022 underwent long-read (ONT) (=27) and short-read (Illumina) sequencing (=18).

A diverse array of micro-organisms can be found on food, including those that are pathogenic or resistant to antimicrobial drugs. Metagenomics involves extracting and sequencing the DNA of all micro-organisms on a sample, and here, we used a combination of culture and culture-independent approaches to investigate the microbial ecology of food to assess the potential application of metagenomics for the microbial surveillance of food. We cultured common foodborne pathogens and other organisms including , spp.

Background: Klebsiella pneumoniae bloodstream infection (KP BSI) is a severe clinical condition characterized by high mortality rates. Despite the clinical significance, accurate predictors of mortality in KP BSI have yet to be fully identified.
Methods: A retrospective analysis was conducted on the clinical data of 90 cases of KP BSI.
Comparison of nasopharyngeal bacteriological profile between patients with diabetes and healthy individuals in Accra, Ghana.
BMC Res Notes

Department of Medical Microbiology, University of Ghana Medical School, P.O. Box KB 4236, Accra, Ghana.
Background: The nasopharynx is characterised by a rich microbial diversity, making it an important endogenous reservoir for respiratory infections. People living with diabetes (PLWD) have a high risk for acquisition of respiratory tract infections, but their nasopharyngeal bacterial flora have rarely been investigated.
Aim: To investigate the nasopharyngeal bacterial flora among PLWD and non-diabetics at the Korle Bu Teaching Hospital in Accra.
