Mecanismos de resistencia a Glicopéptidos en Staphylococcus aureus [PDF]

Kasmera, 2010
Abstract: Glycopeptides (vancomycin and teicoplanin) are an alternative therapeutic in the treatment of severe infections by methicillin-resistant S. aureus strains. However, two resistance mechanisms of S. aureus have already been described: low-level resistance, characterized by an abnormal thickening of the cellular wall, present in the VISA strains,

Mecanismos de resistencia a antibióticos B-lactámicos en Staphylococcus aureus

Kasmera, 2010
Abstract: S. aureus has shown a great power of adaptation to antimicrobial agents, acquiring, step-by- step, resistance to all available antibiotics for treatment of the infections it causes. S. aureus has three major mechanisms of resistance to -lactam antibiotics: enzyme mediated (penicillinase or -lactamase) by which the antibiotic is inactivated ...

Novel insights related to the rise of KPC-producing Enterobacter cloacae complex strains within the nosocomial niche

Frontiers in Cellular and Infection Microbiology, 2022
According to the World Health Organization, carbapenem-resistant Enterobacteriaceae (CRE) belong to the highest priority group for the development of new antibiotics. Argentina-WHONET data showed that Gram-negative resistance frequencies to imipenem have

Resistencia bacteriana a los antibióticos: mecanismos de transferencia

, 2012
La resistencia a los antimicrobianos que han desarrollado las bacterias despertó el interés de los investigadores, ya que esta habilidad adaptativa dificulta el tratamiento y, por ende, la erradicación de enfermedades que se derivan de su acción patógena.

Emergence of colistin resistance in Klebsiella pneumoniae ST15 disseminating blaKPC-2 in a novel genetic platform

Journal of Global Antimicrobial Resistance, 2022
: Objectives: Isolation of colistin- and carbapenem-resistant Klebsiella pneumoniae (CCR-Kp) is increasing in hospital settings worldwide, which is related to increased morbidity, mortality and healthcare costs. The aim of this work was to perform whole-

Molecular studies of phages-Klebsiella pneumoniae in mucoid environment: innovative use of mucolytic agents prior to the administration of lytic phages

Frontiers in Microbiology, 2023
Mucins are important glycoproteins that form a protective layer throughout the gastrointestinal and respiratory tracts. There is scientific evidence of increase in phage-resistance in the presence of mucin for some bacterial pathogens.
