O-antigen serotyping and MALDI-TOF, potentially useful tools for optimizing semi-empiric antipseudomonal treatments through the early detection of high-risk clones.

Mulet X1, García R1, Gayá M1, and Oliver A1 1Hospital Universitario Son Espases,Palma de Mallorca,Spain. Abstract: The increasing prevalence of extensively drug-resistant (XDR) Pseudomonas aeruginosa infections is due to the global spread of defined high-risk clones (HRC). Among them, ST175 is particularly frequent in Spain and France. Here, we evaluated O-antigen serotyping and MALDI-TOF as… Read More ›

Interplay between Peptidoglycan Biology and Virulence in Gram-Negative Pathogens.

Juan C1, Torrens G1, Barceló IM1, Oliver A1 1Hospital Universitario Son Espases,Palma de Mallorca,Spain. The clinical and epidemiological threat of the growing antimicrobial resistance in Gram-negative pathogens, particularly for β-lactams, the most frequently used and relevant antibiotics, urges research to find new therapeutic weapons to combat the infections caused by these microorganisms. An essential previous… Read More ›

Deciphering β-lactamase-independent β-lactam resistance evolution trajectories in Pseudomonas aeruginosa.

Cabot G1, Florit-Mendoza L1, Sánchez-Diener I1, Zamorano L1, Oliver A1 1Hospital Universitario Son Espases,Palma de Mallorca,Spain. Background:While resistance related to the expression of β-lactamases, such as AmpC from Pseudomonas aeruginosa, has been deeply studied, this work addresses the gap in the knowledge of other potential bacterial strategies to overcome the activity of β-lactams when β-lactamases… Read More ›
