SpletUsing 30 clinical isolates of Staphylococcus aureus representative of the most prevalent clones circulating in France, the performance of the Alere™ PBP2a Culture Colony Test (CCT) and the Slidex(®) MRSA detection kit (SMD) were compared in 5 different labs. CCT demonstrated better performance and was easier to conduct in routine. SpletAntimicrobial susceptibility testing was performed using the Kirby–Bauer disk diffusion method and E-tests, confirmation of MRSA status was carried out using PBP2a agglutination assay. Biofilm-production was assessed using the crystal violet (CV) tube-adherence method and the Congo red agar (CRA) plate method.

SpletThis new LFSA biosensor utilizes a cognate aptamer duo binding to pbp2a, a target protein, at 2 different binding sites, exhibiting a sensitive and highly selective response. Our studies have shown successful development of a single yet effective LFSA for pbp2a detection without any special laborious instrumentations. SpletIn this study, a total of 223 isolates collected from 23 patients were submitted to MRSN for WGS and AMR testing. Initial phenotypic testing among eight patient wounds revealed 10 distinct MRSA isolates and one ESBL producing Klebsiella species. PBP2a is well defined to render MRSA strains resistant to virtually all β-lactam antibiotics.
