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).

infections can significantly impact the health and productivity of dairy cattle. Asymptomatic carriage of can make it difficult to identify and monitor this pathogen across a herd. Therefore, a more focused census on dairy farms is needed to better understand the dynamics of asymptomatic carriage.

Understanding colonization dynamics of respiratory pathogens in LTCF residents is essential for effective infection control. This study examines the longitudinal trends in prevalence, persistence, bacterial load, and co-colonization patterns of five respiratory pathogens in three LTCFs in Phoenix, Arizona.

The immune and microbial factors that permit GI colonization remain unknown. Male sex is correlated with enhanced nasal carriage, skin and soft tissue infections, and bacterial sepsis.
