Monitoring fluoroquinolone resistance among ESBL-positive and ESBL-negative Escherichia coli strains isolated from urinary tract infections: An alert for empirical treatment

Revista da Sociedade Brasileira de Medicina Tropical, 2023
Background: Bacterial resistance to extended-spectrum beta-lactamases (ESBL) is present worldwide. Empirical antibiotic therapy is often needed, and the use of fluoroquinolones, such as ciprofloxacin and norfloxacin, is common.

Fluoroquinolone resistance in Neisseria meningitidis in Spain [PDF]

Journal of Antimicrobial Chemotherapy, 2007
To assess the ciprofloxacin resistance of Neisseria meningitidis isolated from 1999 through 2006 in Spain, susceptibility testing was conducted on 5300 isolates.Ten isolates showed MICs of ciprofloxacin ranging between 0.06 and 0.25 mg/L, and they were characterized by analysis for mutations within the quinolone resistance determining regions (QRDRs ...

Effects of earthworms on the fate of tetracycline and fluoroquinolone resistance genes of sewage sludge during vermicomposting.

Bioresource Technology, 2018
Diverse antibiotic resistance genes (ARGs) present in sewage sludge are difficult to be eliminated using conventional sludge treatment processes. To date, little remains known on the fate of the ARGs during vermicomposting of sludge.

Beyond Biomimetics: Pathology‐Informed Engineering Rescues Reconstituted HDL From Inflammatory Dysfunction for Sepsis Immunotherapy

Advanced Science, EarlyView.
A pathology‐informed engineering strategy rescues reconstituted HDL from inflammatory dysfunction in sepsis. By integrating a ceria nanozyme‐celastrol coordination complex, the platform preserves HDL structure and endotoxin handling, sustains hierarchical intracellular delivery, and enhances immunoregulation across pathological models, translating ...

First characterization of fluoroquinolone resistance in Streptococcus suis

, 2007
We have identified and sequenced the genes encoding the quinolone-resistance determining region (QRDR) of ParC and GyrA in fluoroquinolone-susceptible and -resistant Streptococcus suis clinical isolates.

Fluoroquinolone resistant bacterial isolates from the urinary tract among patients attending hospitals in Bushenyi District, Uganda

The Pan African Medical Journal, 2020
INTRODUCTION: Bacterial resistance to fluoroquinolones is on the rise globally, bacteria causing urinary tract infections (UTIs) are no exception to this fact. Judicious use of the current antibiotics by clinicians is therefore deemed necessary to combat

The antimicrobial susceptibility, resistance mechanisms and phylogenetic structure of S. Typhi isolated in 2005-2018 in the Russian Federation

Инфекция и иммунитет, 2020
Here we present current global epidemiological and microbiological trends for typhoid fever, as well as describe antimicrobial susceptibility and resistance mechanisms of S. Typhi. The data on examining 299 S. Typhi isolates collected in 2005—2018 in the

Fluoroquinolone resistance

BMJ, 1998
Fluoroquinolones are highly active, broad spectrum antibiotics with many uses in both human and veterinary medicine. As with other classes of antibiotic, however, decreased susceptibility or resistance to these agents has developed. Resistance is usually chromosomally mediated so the spread of resistant bacteria contributes to the high numbers of ...

Fluoroquinolone-resistantStreptococcus pneumoniae

Emerging Infectious Diseases, 2006
To the Editor: In pneumococci, resistance to fluoroquinolones is associated with chromosomal mutations in the quinolone-resistance–determining regions (QRDR) of type II topoisomerase enzymes, predominantly gyrA and parC. Several mutations have been described in these enzymes, but only a few have been shown by in vitro studies to confer resistance: S81F

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
