Article Abstract

We investigated the prevalence and characteristics of Cefazolin inoculum effect (CInE) among clinical MSSA isolates in Japan. Although 35.5 % (39 isolates) were positive for the blaZ gene, none met the phenotypic criteria for CInE. Our findings suggested a very low prevalence of CInE among MSSA isolates in our clinical setting.

Background: There are limited in vitro synergistic studies on dalbavancin against enterococci. We aimed to assess the in vitro activity of dalbavancin against Enterococcus faecalis strains, and to explore the interaction between dalbavancin and β-lactams.

Methods: MIC and MBC values were determined against a panel of 10 clinical isolates and two reference strains of E.

Introduction Intra-operative surgical site irrigation with antibiotics is believed to reduce the risk of infection in spine surgeries involving instrumentation. However, despite its frequent use, there is limited supporting evidence for this practice. This prospective in-vitro study aims to evaluate the effect of short-term antibiotic exposure on the growth of common pathogens associated with wound infections.

Clinical features and medical-surgical management overweight the inoculum effect and genotypic characteristics of MSSA in infective endocarditis.

Objectives: MSSA remains the leading cause of infective endocarditis (IE) and is responsible for significant mortality. While clinical factors tied to mortality are well documented, possible contributing strain-specific characteristics have not been extensively explored. This study investigates MSSA phenotypic and genotypic characteristics and medical-surgical data related to Day-90 mortality in IE.

Background: The cefazolin inoculum effect (CzIE), defined here as a cefazolin MIC at high inoculum (107 colony-forming units/mL)  ≥16 mg/L in MSSA, has been associated with less favourable clinical outcomes. However, detection of this phenotype is challenging in the clinical microbiology laboratory. We previously described modification of a rapid nitrocefin test using ampicillin disks rather than ampicillin powder for induction of the Staphylococcus aureus β-lactamase (BlaZ).

Background: Inflatable penile prostheses (IPPs) have been shown to harbor biofilms in the presence and absence of infection despite exposure to various antimicrobials. Microbes persisting on IPPs following antibiotic exposure have not been adequately studied to assess biofilm formation capacity and antibiotic resistance.

Aim: In this study, we aimed to assess these properties of microbes obtained from explanted infected and non-infected IPPS using an in vitro model.
