Of the genes in that region, we propose that SLC9A6 is the most likely to play an important role as mutations in this gene lead to Christianson syndrome, in which patients may have microcephaly and weight loss.

These results suggest that tedizolid represents a promising therapeutic option for the treatment of CF-associated MRSA/MSSA infections, having potent in vivo activity and low resistance potential.
This review focuses on the clinical significance of MRSA infections and new approaches for the laboratory diagnosis and epidemiologic typing of MRSA strains.
Currently, this organism's ability in developing resistance to antibiotics is notorious; methicillin-resistant Staphylococcus aureus-MRSA-is known for its resistance to methicillin, oxacillin, and others.
We found that passive immunization with either a monoclonal antibody (mAb) neutralizing alpha-hemolysin or a broadly cross-reactive mAb that neutralize Panton-Valentine leukocidin, leukocidin ED and gamma-hemolysins HlgAB/HlgCB only conferred partial protection, whereas the combination of those two mAbs conferred significant protection in a rabbit model of necrotizing pneumonia caused by the USA300 MRSA epidemic clone.
Levonadifloxacin displayed potent activity against contemporary MRSA and fluoroquinolone-resistant staphylococcal isolates, thus offering a valuable IV as well as an oral therapeutic option for the treatment of ABSSSIs.
Whole genome sequencing and mass spectrometry of the purified peptide confirmed that <i>S. capitis</i> APC2923 produces a 3458 Da bacteriocin, designated nisin J, which exhibited antimicrobial activity against a range of Gram-positive pathogens including MRSA and <i>Cutibacterium acnes.</i> The gene order in the nisin J gene cluster (<i>nsjFEGBTCJP</i>) differs from those of other nisin variants, in that it is lacking the nisin regulatory genes, <i>nisRK</i>, as well as the nisin immunity gene, <i>nisI</i> Nisin J has 9 amino acid changes when compared to prototypical nisin A; 8 amino acid substitutions, 6 of which are not present in other nisin variants (Ile4Lys, Met17Gln, Gly18Thr, Asn20Phe, Met21Ala, Ile30Gly, Val33His and Lys34Thr) and an extra amino acid close to the C-terminus, rendering nisin J the only nisin variant to contain 35 amino acids.
Collectively, these findings expand our understanding of the genetic diversity of CS and further elucidate a critical role for SLC9A6/NHE6 in fine-tuning recycling endosomal pH and cargo trafficking, processes crucial for the maintenance of neuronal polarity and mature synaptic structures.
Our findings establish the Slc9a6 KO mouse as a relevant tool for studying the sensory deficits in CS, and highlight selective vulnerabilities in relevant cell populations that may contribute to this phenotype.
Univariate analysis revealed that infection was more frequent in patients with MRSA-carriage (p < 0.001), in case of previous catheter-related infection (p < 0.05) and of bacteremia or bacteriuria in the period of 3 months before catheter implantation (p < 0.001).
The main goal of this study was to evaluate PK/pharmacodynamic (PKPD) target attainment when using a 600 mg intravenous q12h linezolid dose against MRSA in obese patients with pneumonia.
More patients with qSOFA ≥2 had altered mentation (23% vs 5%, p < 0.0001), were infected with MRSA (42% vs 30%, p = 0.03), had endocarditis or pneumonia (29% vs 15%, p = 0.0028), and bacterial persistence ≥4d (34% vs 20%, p = 0.0039) compared to qSOFA <2 patients.
Coupled to a low cytotoxic activity, we believe our lead compound can be developed into a topical antibacterial agent to replace mupirocin as the first-line drug for treating MRSAskin infections.
To overcome the increasing difficulties in the clinical management of SSTI due to MRSA, new prophylactic and therapeutic approaches are urgently needed and a preventive vaccine would be welcome.
