Antimicrobial resistance is considered by WHO as one of the most important threats to public health in twenty-first century. According forecasts, 2025, many first-line antimicrobials will lose their effectiveness and «post-antibiotic era» begin. Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp. representatives ...
This work describes the characterization of plasmid-mediated quinolone-resistance (PMQR) genes from a multicenter study of ESBL-producing Enterobacteriaceae pediatric clinical isolates in Mexico. The PMQR gene-positive isolates were characterized with respect to ESBLs, and mutations in the GyrA and ParC proteins were determined. The phylogenetic relationship was established by PFGE and the tran...
Bacteria may be resistant to antibacterial drugs because of some alterable property of the cell or the environment ('phenotypic resistance') or some alteration of the usual genetic properties of the cell ('genotypic resistance'). Genotypic resistance can be mediated by a mutation of the bacterial chromosome or the infection of the cell by an extrachromosomal element, e.g. an R factor. The prope...
Background and Aims: Uropathogenic Escherichia coli (UPEC) are considered major reservoir for genes encoding antimicrobial resistance. The mechanism of resistance and persistence of UPEC has been attributed to the production of biofilm and Extended Beta Lactamase (ESBL). This hospital-based prospective study determined how biofilm and ESBL production facilitate antibacterial resistance amongst ...
