Unlabelled: Coagulase-negative staphylococci are the most common cause of late-onset sepsis in premature neonates. The optimal approach in persistent coagulase-negative staphylococcal bacteremia, despite adequate treatment with glycopeptides, is not well established. A retrospective study was conducted on preterm neonates with persistent coagulase-negative staphylococcal bacteremia treated with the combination of vancomycin-rifampicin. Ten cases were included, with a median gestational age of 26 weeks (range 24 weeks + 3 days-31 weeks + 4 days, interquartile range 25 weeks + 3 days-29 weeks + 3 days) and a median birth weight of 715 g (range 555-2,030). The median age at the onset of infection was 9 days (range 5-37). The most frequent clinical presentation was apnea or increased ventilatory support. Bacteremia persisted for a median of 9 (range 6-19) days until rifampicin initiation. Bacteremia was resolved in all cases on vancomycin-rifampicin with no serious side effects.
Conclusion: Our study provides data supporting the safety and efficacy of vancomycin-rifampicin combination for the treatment of persistent coagulase-negative staphylococcal bacteremia in preterm neonates.

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).

: The main aim of this study was to describe the epidemiology of infected non-unions (INUs) managed at an Infectious Disease (ID) referral centre and to investigate the factors associated with treatment failure. : This was an observational retrospective study on adult patients with INUs managed between 2012 and 2018 at the ID Unit of the IRCCS Azienda Ospedaliero-Universitaria di Bologna, an Italian ID referral centre for bone and joint infections. Patients were observed for at least 24 months.

Coagulase-negative (CoNS) is a rare cause of UTIs in children and is often regarded as a contaminant in urine samples. We report a case of acute focal bacterial nephritis (AFBN) and bacteremia caused by following an upper respiratory infection in a pediatric patient. The patient, a four-year-old girl, presented with fever, cough, and a runny nose two days before being referred to our hospital due to persistent fever and poor oral intake.

Introduction: This study identifies as a new coagulase-negative staphylococcal species isolated from diabetic foot osteomyelitis (DFOM) and provides an in-depth analysis of its pathogenic and virulence profile, as well as demonstrating its potential to cause infection.
Methods: The NSD001 strain was examined for its planktonic growth, biofilm production, and phagocytosis rates in murine macrophages compared to NSA739. Additionally, persistence and replication within human osteoblasts were investigated, while the zebrafish embryo model was employed to assess virulence.
Since the era of the widespread introduction of antibiotics into the human sphere of activity, the problem of antimicrobial resistance has become an urgent and very important topic around the world. Recently, coagulasonegative staphylococci (CoNS), which are representatives of opportunistic microorganisms of the microbiome of the skin and mucous membranes of healthy people, have made a certain contribution to its progression. For a long time, they did not pose a threat to patients, but in recent decades among microorganisms they have been seeded in more than two-thirds of patients with postoperative mediastinitis, catheter-associated infections, as well as from wounds of the neck vessels and the inguinal region separated by pacemaker beds.
