In our recent experience with methicillin-resistant Staphylococcus aureus (MRSA) infections in 488 patients undergoing thoracic cardiovascular surgery, we found only 2 MRSA infections (one sternal and one graft site). Both patients received preoperative bacitracin and had a negative nares culture for MRSA before the initiation of bacitracin therapy. We conclude that preoperative MRSA screening cultures and bacitracin prophylaxis are neither clinically efficacious nor cost-effective in predicting or preventing MRSA in patients undergoing thoracic cardiovascular surgery.

Background: Nemonoxacin is a new quinolone with an antibacterial efficacy against methicillin-resistant Staphylococcus aureus (MRSA). Certain sequence types (STs) have been emerging in Taiwan, including fluoroquinolone-resistant ST8/USA300. It's an urgent need to determine nemonoxacin susceptibility against ST8/USA300 and other emerging lineages, if any.

Bacterial-infected wounds usually lead to slow wound healing due to increased inflammation, especially wounds infected by drug-resistant bacteria, which is a serious challenge in the biomedical field. Traditional antimicrobial strategies such as antibiotics lead to a significant increase in drug-resistant strains and have limited efficacy. Therefore, there is an urgent need to develop multifunctional dressings with excellent antibacterial activity and promotion of wound healing.

The rapid and reliable diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) is essential for preventing the spread of MRSA infections and guiding therapeutic strategies. However, there is still a huge challenge in further simplifying MRSA detection procedures and improving detection selectivity to reduce false-positive results. In this study, we developed a derivative CRISPR-associated protein 9/CRISPR-derived RNA Linked Immunological Assay (dCLISA) for the sensitive and specific detection of MRSA.

Ligand-functionalized InP-based quantum dots (QDs) have been developed as an innovative class of nontoxic photosensitizer suitable for antimicrobial applications, aimed at reducing or preventing pathogen transmission from one host to another via high contact surfaces. A hot injection method followed by functionalization via ligand exchange with 9-anthracene carboxylic acid (ACA) yielded the desired core/shell InP/ZnSe/ZnS QDs. Transmission electron microscopy (TEM) revealed these QDs to be uniform in size (∼3.

Omadacycline is a novel antimicrobial belonging to the tetracycline class. It has the ability to evade both efflux and ribosomal methylation types of resistance and therefore has an expanded spectrum compared to other tetracycline agents. Omadacycline is active against a number of multidrug-resistant bacteria, including macrolide and doxycycline-resistant methicillin-resistant (MRSA), vancomycin-resistant Enterococcus, and several enteric gram-negative bacilli.
