Bloodstream Infection Caused by in an Immunocompetent Patient.

is a facultative anaerobe Gram-positive bacillus, which is considered a zoonotic pathogen. causes erysipeloid, mainly in occupational groups such as veterinarians, slaughterhouse workers, farmers, and fishermen. Two cutaneous forms (localised and generalised) and a septicaemic form have been described.

Impact of Whole Genome Sequencing to investigate transmission of Serratia marcescens in Neonatal Intensive Care Unit.

Newborns admitted to neonatal intensive care units (NICU) are at increased risk of health care-associated infections. Serratia marcescens represent the third most common pathogen in NICU outbreaks. Here we present an outbreak investigation performed using Whole Genome Sequencing (WGS) analyses and the control measures implemented to limit the spread of S.

Clinical isolates of ST131 OXA-244-positive , Italy, December 2022 to July 2023.

The dissemination of carbapenemase-producing although still at low level, should be continuously monitored. OXA-244 is emerging in Europe, mainly in . In Italy, this carbapenemase was reported from an environmental river sample in 2019.

One-year surveillance for hypervirulent detected carbapenem-resistant superbugs.

Hypervirulent (hvKp) can cause infections in clinically healthy people, such as young and immunocompetent patients. Genes involved in the capsule synthesis or those encoding the siderophores have been adopted as predictors of hvKp. Certain sequence types, such as ST23 and ST86, have been associated with hvKp strains, too.

Rapid spread of a novel NDM-producing clone of CC147, Northern Italy, February to August 2023.

New Delhi metallo-beta-lactamase (NDM)-producing () ST147 caused a large multi-hospital outbreak in Italy from 2018 to 2021. We describe a new ST6668 NDM-producing clone, belonging to CC147, which rapidly spread across hospitals in the Pavia province (Northern Italy) from February to August 2023. Genomic analyses revealed that ST6668 is different from ST147 and fast evolving.

Surveillance in a Neonatal Intensive Care Unit Allowed the Isolation of a Strain of VIM-Producing .

Here, we describe the isolation of a strain of the genus encoding a VIM carbapenemase, the first to our knowledge. The strain, isolated from a rectal swab of a 10-day-old newborn admitted to a neonatal intensive care unit (NICU), was identified through whole-genome sequencing analyses as . The strain harbored the carbapenemases gene .
