Enhanced Killing of Methicillin-Resistant Staphylococcus aureus with Ceftaroline or Vancomycin in Combination with Carbapenems.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with high rates of treatment failure, even when antibiotics showing in vitro susceptibility are used. Early optimization of therapy is crucial to reduce morbidity and mortality. Building on our previous research on carbapenem therapy for methicillin-susceptible S.

Self-assembly of isolated plasmonic dimers with sub-5 nm gaps on a metallic mirror.

Realizing plasmonic nanogaps with a refractive index ( = 1) environment in metallic nanoparticle (NP) structures is highly attractive for a wide range of applications. So far in self-assembly-based approaches, without surface functionalization of metallic NPs, achieving such extremely small nanogaps is challenging. Surface functionalization introduces changes in the refractive index at nanogaps, which in turn deteriorates the desired plasmonic properties.

Differential gene expression analysis shows that cephalosporin resistance is intrinsic to Clostridioides difficile strain 630.

Clostridioides difficile infection (CDI) is the most common nosocomial infection in the US. CDI has become a growing concern due to C. difficile's resistance to several antibiotics, including cephalosporins.

Immunoinformatic design of a multivalent vaccine against and its evaluation in a murine model using a DNA prime-protein boost strategy.

Introduction: The development of effective vaccines against is critical due to its significant impact on human and animal health. The objective of this study was to design and evaluate and a multivalent vaccine based on the immunogenic potential of three selected open reading frames (ORFs) of .

Methods: The designed construct, named S22, was analyzed to evaluate its physicochemical properties, antigenicity, allergenicity and toxicity.

A Case of Life-Threatening Abdominal Wall Hematoma Formation in a Patient on Warfarin Therapy with Concurrent Influenza Infection.

Warfarin therapy provides extensive antithrombotic benefits and, thus, is widely used in the general population. However, as with most medications, there are also risks associated with warfarin use. Specifically, because of the narrow therapeutic window of this drug, patients taking it are at a much higher risk of accidental bleeding.
