Emergence of fluoroquinolone resistance and possible mechanisms in clinical isolates of Stenotrophomonas maltophilia from Iran

Scientific Reports, 2021
Stenotrophomonas maltophilia exhibits wide spectrum of fluoroquinolone resistance using different mechanisms as multidrug efflux pumps and Smqnr alleles.

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 ...

Increased fluoroquinolone resistance with time in Escherichia coli from >17,000 patients at a large county hospital as a function of culture site, age, sex, and location

BMC Infectious Diseases, 2008
Background Escherichia coli infections are common and often treated with fluoroquinolones. Fluoroquinolone resistance is of worldwide importance and is monitored by national and international surveillance networks.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

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

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

Population pharmacokinetics of levofloxacin in breastmilk in patients with rifampicin‐resistant tuberculosis

British Journal of Clinical Pharmacology, EarlyView.
Levofloxacin is a widely used antibiotic included in rifampicin‐resistant tuberculosis (RR‐TB) treatment. Data describing levofloxacin concentrations in breastmilk and infant exposure are limited. We analysed data from two South African studies of breastfeeding women receiving levofloxacin (750–1000 mg daily) for RR‐TB.

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

Fluoroquinolone Resistance inStreptococcus pyogenes [PDF]

Clinical Infectious Diseases, 2003
Streptococcus pyogenes isolated from blood and urine samples obtained from a 78-year-old woman was tested for susceptibility, and fluoroquinolone resistance (minimum inhibitory concentration of levofloxacin, 16 microg/mL) was found. DNA amplification and sequencing revealed a serine81-->tyrosine substitution in gyrA and 2 substitutions in parC ...
