Methicillin-resistant Staphylocoocus aureus (MRSA) harboring mecA(LGA251) has been isolated from humans and ruminants. Database screening identified this MRSA variant in cats, dogs, and a guinea pig in Germany during 2008-2011. The novel MRSA variant is not restricted to ruminants or humans, and contact with companion animals might pose a zoonotic risk.

The increasing threat of antimicrobial-resistant bacteria, particularly Staphylococcus aureus, which rapidly develops multidrug resistance and commonly colonizes wound surfaces, demands innovative strategies. Phage-encoded endolysins offer a dual-purpose approach as topical therapies for infectious skin wounds and synergistic agents to reduce high-dose antibiotic dependence. This study explores recombinant CHAPk (rCHAPk), efficiently synthesized within 3 h, displaying broad-spectrum antibacterial activity against 11 Gram-positive strains, including resistant variants, with rapid bactericidal kinetics.

Background: Methicillin-resistant (MRSA) has been an issue in healthcare since the 1960s. It was initially found only in healthcare facilities, but in the late 1990s it began to be seen with no healthcare connexion. The mechanisms of intercontinental and national spread are not fully understood, as sometimes novel outbreaks occur without any identifiable source or connexion to locally dominant clonal clusters.

Background: Nasopharyngeal colonization with Staphylococcus aureus is a risk factor for subsequent infection. Isolates from colonization can therefore provide important information on virulence factors and antimicrobial resistance when data from clinical isolates are lacking. The aim of this study was to assess colonization rates, resistance patterns and selected virulence factors of S.

Objectives: Staphylococcus aureus is a major cause of bloodstream infections. The recent epidemiological features and antimicrobial resistance trend were analyzed for methicillin-resistant and susceptible S. aureus (MRSA/MSSA) isolates from blood samples in northern Japan.

Epidemic infections and spreading antibiotic resistance require diagnostic tests that can be rapidly adopted. To reduce the usually time-consuming adaptation of molecular diagnostic tests to changing targets, we propose the novel approach of a repurposable sensing electrode functionalization with a universal, target-independent oligonucleotide probe. In the liquid phase covering the electrode, the target sequence is amplified by MD LAMP (mediator-displacement loop-mediated isothermal amplification) releasing a generic methylene blue-labeled mediator, which specifically hybridizes to the solid-phase probe.
