Mechanisms of Resistance to Quinolones and Epidemiological Significance of Salmonella spp.

Acta Veterinaria, 2016
Bacteria develop resistance to antimicrobial agents by a number of different mechanisms. The resistance to (fluoro)quinolones in Salmonella is of particular importance especially if therapy in humans is required.

Plasmid-mediated qnrA1 in Klebsiella pneumoniae ST147 in Recife, Brazil

International Journal of Infectious Diseases, 2014
Objectives: Qnr-mediated quinolone resistance is increasingly detected worldwide, but few studies have been carried out so far in Brazil. The aim of this study was to test for qnr determinants in isolates of ciprofloxacin-resistant Klebsiella pneumoniae.

Peptides as quorum sensing molecules : measurement techniques and obtained levels in vitro and in vivo [PDF]

, 2017
The expression of certain bacterial genes is regulated in a cell-density dependent way, a phenomenon called quorum sensing. Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by ...

Ecology of antimicrobial resistance: humans, animals, food and environment [PDF]

, 1970
Antimicrobial resistance is a major health problem. After decades of research, numerous difficulties in tacklingresistance have emerged, from the paucity of new antimicrobials to the inefficient contingency plans to reduce the use ofantimicrobials ...
