In Brazil the knowledge about methicillin-resistant Staphylococcus aureus infection in cystic fibrosis patients is scarce. This study aimed to determine the incidence of respiratory tract colonization and the identification rates after a standardized treatment. A retrospective cohort was performed highlighting the history of respiratory colonizations between January 2008 and June 2015. Patients under the age of 21 years with cystic fibrosis confirmed by sweat test or genetic study receiving care at the outpatient clinics of a Teaching Hospital were included. The treatment consisted of trimethoprim/sulfamethoxazole, rifampicin, nasal mupirocin and chlorhexidine 2%. The mean follow-up period was of 22.2 months and those with ≥3 negative cultures were considered free of methicillin-resistant Staphylococcus aureus. Forty-two patients were included. Methicillin-resistant Staphylococcus aureus was identified in six patients. Most patients had methicillin-sensitive S. aureus isolation prior to methicillin-resistant Staphylococcus aureus. Five children used the standardized treatment, none presented side effects. Only one child had a new isolation of methicillin-resistant Staphylococcus aureus during follow-up (after 20 months). The incidence of methicillin-resistant Staphylococcus aureus infection was high and occurred in young patients. The therapeutic regimen was effective, safe and being a good option to treat methicillin-resistant Staphylococcus aureus infection.

A 2019 nationwide study in Japan revealed the predominant methicillin-resistant Staphylococcus aureus (MRSA) types in bloodstream infections (BSIs) to be sequence type (ST)8-carrying SCC type IV (ST8-MRSA-IV) and clonal complex 1-carrying SCC type IV (CC1-MRSA-IV). However, detailed patient characteristics and how these MRSA types evolve over time remain largely unknown. In this long-term single-center study, MRSA strains isolated from blood cultures at Nagasaki University Hospital from 2012 to 2019 were sequenced and analyzed.

In addressing the formidable challenge posed by methicillin-resistant Staphylococcus aureus (MRSA), this investigation elucidates a novel therapeutic paradigm by specifically targeting the virulence factor sortase A (SrtA) utilizing Tubuloside A (TnA). SrtA plays a critical role in the pathogenicity of MRSA, primarily by anchoring surface proteins to the bacterial cell wall, which is crucial for the bacterium's ability to colonize and infect host tissues. By inhibiting SrtA, TnA offers a novel and distinct strategy compared to traditional antibiotics.

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: The Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a serious adverse reaction that occurs weeks after the onset of drug exposure. DRESS syndrome is commonly associated with antiseizure drugs, sulfa drugs, and antibiotics.
Case Presentation: This was a case report of a 20-year-old female who suffered from DRESS due to vancomycin with symptoms similar to the Redman syndrome.
