Enzybiotics are promising alternatives to conventional antibiotics for drug-resistant infections. Exolysins, as a class of enzybiotics, show antibacterial effects against methicillin-resistant Staphyl...
This study designed a chimeric exolysin by fusing the Cell-binding domain (SH3b) from Lysostaphin with the lytic domain (LYZ2) from the gp61 enzyme. Subsequently, LYZ2-SH3b was cloned and expressed in...
Analysis of bioinformatics showed that LYZ2-SH3b was stable, soluble, and non-allergenic. Protein purification was performed with a 0.8 mg/ml yield for LYZ2-SH3b. The plate lysis assay results indicat...
The study suggests that phage endolysins, such as LYZ2-SH3b, may represent a promising new approach to treating MRSA infections, particularly in cases where antibiotic resistance is a concern. But fur...
This study describes differentiation of methicillin-resistant Staphylococcus aureus (MRSA) isolates belonging to different genotype groups by the combination of electrophoretic techniques, transient i...
Staphylococcus aureus is the primary cause of bacteremia, and methicillin-resistant S. aureus bacteremia is associated with a high mortality rate. Methicillin-resistant S. aureus clones are widespread...
The prevalence and virulence of pathogens such as methicillin-resistant Staphylococcus (S.) aureus (MRSA), which can cause recurrent skin infections, are of significant clinical concern. Prolonged ant...
Methicillin-resistant Staphylococcus aureus (MRSA) strains are tolerant of conventional antibiotics, making them extremely dangerous. Previous studies have shown the effectiveness of proton motive for...
Methicillin-resistant Staphylococcus aureus (MRSA) can cause serious infections and empiric treatment regimens in children frequently include an anti-MRSA antibiotic. Studies in adults have demonstrat...
This was a single-site, retrospective cohort study of pediatric patients admitted with a suspected infectious diagnosis who had an MNS performed during their hospitalization between June 1, 2018 and N...
This study identified 172 patients who met the inclusion criteria. Eleven (6.4%) nasal swabs were positive for MRSA and 10 (5.8%) microbiological cultures from suspected sources of infection were iden...
MNS has a high NPV and low PPV in children. MNS can be utilized as an antimicrobial stewardship tool to guide the safe de-escalation of anti-MRSA antibiotics in children....
Necrotizing pneumonia caused by methicillin-resistant Staphylococcus aureus can lead to the formation of pneumatoceles in the lungs. Standard treatment guidelines are not available due to the rarity o...
Baby H. required prolonged respiratory support and supplemental oxygen to maintain appropriate oxygen saturation parameters for infants more than 34 weeks' gestation corrected. He was found to have mu...
Baby H. was a former 32.2-week gestation male infant diagnosed with pneumonia caused by necrotizing methicillin-resistant Staphylococcus aureus leading to pneumatocele formation in both lungs....
Baby H. was managed with aggressive antibiotic therapy and then was conservatively managed until he received a tracheostomy tube on day of life (DOL) 75 to prepare for discharge home....
Baby H. was discharged from the neonatal intensive care unit (NICU) on DOL 113 with a tracheostomy tube for prolonged mechanical ventilatory support and a gastrostomy tube for nutrition. Numerous foll...
While methicillin-resistant Staphylococcus aureus pneumatoceles are uncommon in the NICU setting, it is important for neonatal care providers to be aware of the causes and treatment choices currently ...
Methicillin-resistant Staphylococcus aureus (MRSA), a globally widespread pathogen that is highly resistant to antibiotics, can lead to serious infection, and has fairly limited treatment options. Ove...
Staphylococcus aureus, a commensal bacterium, colonizes the skin and mucous membranes of approximately 30% of the human population. Apart from conventional resistance mechanisms, one of the pathogenic...
Analyzing non-repetitive clinical isolates of MRSA collected from seven provinces and cities in China between 2014 and 2020, it was observed that 53.2% of the MRSA isolates exhibited varying degrees o...
MRSA strains with biofilm production capability warrant increased vigilance....
Methicillin-resistant Staphylococcus aureus (MRSA) infections impose a considerable burden on health systems, yet there is remarkable variation in the global incidence and epidemiology of MRSA. The MA...
Operational definitions of success were defined in consortium meetings to compose a balanced strain collection of successful and sporadic MRSA isolates. Isolates were subjected to antimicrobial suscep...
Heterogeneity of MRSA isolate collections across countries hampered the use of a unified operational definition of success; therefore, country-specific approaches were used to establish the MACOTRA st...
Our results are the strongest yet to associate MRSA antibiotic resistance profiles and antibiotic usage with the incidence of infection and successful clonal spread, which varied by country. Harmonize...
