The genus Aeromonas belongs to the Aeromonadaceae family and comprises a group of
Gram-negative bacteria widely distributed in aquatic environments, with some species able …

Aquaculture is the productive activity that will play a crucial role in the challenges of the
millennium, such as the need for proteins that support humans and the respect for the …

Over the past decade, the genus Aeromonas has undergone a number of significant
changes of practical importance to clinical microbiologists and scientists alike. In parallel …

Aeromonas hydrophila is a Gram-negative, oxidase-positive, facultative, anaerobic,
opportunistic aquatic pathogen. A. hydrophila produces virulence factors, such as …

Fluoroquinolones are an important class of wide‐spectrum antibacterial agents. The first
quinolone described was nalidixic acid, which showed a narrow spectrum of activity. The …

Plasmid‐mediated quinolone resistance (PMQR) was late in being discovered. Nalidixic
acid, the first quinolone to be used clinically, was introduced in 1967 for urinary tract …

In 1998, the first plasmid-mediated gene involved in quinolone resistance (currently named
qnrA1) was reported. Extra qnr-like plasmid-mediated genes (qnrB, qnrS, qnrC, qnrD) and …

Resistance to quinolones and fluoroquinolones is being increasingly reported among
human but also veterinary isolates during the last two to three decades, very likely as a …

Recently, several plasmid-mediated quinolone resistance (PMQR) genes conferring low
levels of quinolone resistance have been discovered. To evaluate the temporal change in …

While the description of resistance to quinolones is almost as old as these antimicrobial
agents themselves, transferable mechanisms of quinolone resistance (TMQR) remained …
