Novel photoaffinity labeled fusidic acid analogues were obtained by a synthetic sequence employing a Wittig reaction between a fusidic acid aldehyde and benzyl bromides in the key step. Three commonly used photoreactive groups, benzophenone, trifluoromethyldiazirine, and aryl azide, were used. The photoaffinity labeled fusidic acid analogues demonstrated a potent antibacterial activity (MIC 0.016-4 microg/mL) and therefore represent a potential tool for the elucidation of the interactions between fusidic acid and its receptor EF-G.

Methicillin-resistant Staphylococcus aureus (MRSA) continues to pose significant challenges in healthcare settings due to its multi-drug resistance (MDR) and virulence. This retrospective study examines the molecular and resistance profiles of MRSA isolates from a tertiary care hospital in Saudi Arabia, providing valuable insights into regional epidemiology. A total of 190 MRSA strains were analysed to assess antimicrobial susceptibility, genetic diversity, and virulence factors.

Infection caused by drug-resistant Staphylococcus aureus is a serious public health and veterinary concern. Lack of a comprehensive understanding of the mechanisms underlying the emergence of drug-resistant strains, it makes S. aureus one of the most intractable pathogenic bacteria.
View Article and Find Full Text PDFA new fusidic acid-loaded hydrogel film was prepared via the solvent casting technique using alginate and Aloe vera. The hydrogel films were optimized using different ratios of sodium alginate, Aloe vera, and glycerin. The films containing 10% glycerin (w/w of alginate) exhibited the best appearance.

Objectives: Sheep farming represents an important economic sector in Algeria, and the potential dissemination of methicillin-resistant Staphylococcaceae (MRS) is a critical veterinary and public health concern. This study aimed to determine the prevalence and types of MRS in ovine in Algeria and characterize them using whole-genome sequencing (WGS) analysis.
Methods: Two hundred sheep from twenty different Algerian farms across three regions were screened for nasal colonization with MRS.

Livestock-associated fusidic acid-resistant Staphylococcus aureus (FRSA) is frequently linked to global public health hazards. This study aimed to ascertain the prevalence and molecular characteristics of FRSA isolated from food animal products in South Korea from 2010 to 2021. We obtained a total of 3980 S.
