Mechanisms of Reduced Susceptibility to Ciprofloxacin in Escherichia coli Isolates from Canadian Hospitals

Canadian Journal of Infectious Diseases and Medical Microbiology, 2012
OBJECTIVE: To determine whether plasmid-mediated quinolone resistance (PMQR) determinants play a role in the increasing resistance to fluoroquinolones among Escherichia coli isolates in Canadian hospitals, and to determine the mechanisms of reduced ...

Pathogenicity and Antimicrobial‐Resistance Profiles of Escherichia coli Isolated From Faeces of Tibetan Pigs Reared Under Intensive Conditions

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Tibetan pig farms host diverse Escherichia coli strains that resist multiple antibiotics and carry important disease genes, such as astA. These traits jump easily between bacterial groups, marking intensive pig production as a key reservoir and signalling the need for integrated animal–human surveillance and more careful antibiotic use.

Co‐Occurrence of Biofilm Formation and Disinfectant–Antimicrobial Resistance in Staphylococcus spp. Along the Dairy Production Chain

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT This study aims to investigate the co‐occurrence of biofilm formation and resistance to disinfectants and antimicrobial agents in Staphylococcus spp. isolated from different stages of the dairy production chain, and to assess the contribution of these traits to persistence in dairy processing environments. A total of 51 Staphylococcus isolates,

Impact of co-existence of PMQR genes and QRDR mutations on fluoroquinolones resistance in Enterobacteriaceae strains isolated from community and hospital acquired UTIs

BMC Infectious Diseases, 2019
Background Fluoroquinolones are commonly recommended as treatment for urinary tract infections (UTIs). The development of resistance to these agents, particularly in gram-negative microorganisms complicates treatment of infections caused by these ...

Highly Resolved Community Sewage Metagenomics Unveiling Landscape and Transmission Patterns of Antibiotic Resistome in Hong Kong Populations

Advanced Science, Volume 13, Issue 20, 9 April 2026.
A large‐scale, high‐resolution antimicrobial resistance (AMR) surveillance in Hong Kong community sewage combining short‐ and long‐read sequencing. The resistome profile is comprehensively characterized, and this upstream sampling strategy demonstrated superiority in reflecting the human gut resistome.

Investigation of plasmid-mediated quinolone resistance in Pseudomonas aeruginosa clinical isolates

Indian Journal of Medical Microbiology, 2014
To investigate plasmid-mediated quinolone resistance in clinical isolates of Pseudomonas aeruginosa with the polymerase chain reaction (PCR). The plasmid-mediated quinolone resistance genes have been identified in many bacteria within the Enterobactericeae family, they have not been detected in P. aeruginosa isolates.

The Current Case of Quinolones: Synthetic Approaches and Antibacterial Activity

Molecules, 2016
Quinolones are broad-spectrum synthetic antibacterial drugs first obtained during the synthesis of chloroquine. Nalidixic acid, the prototype of quinolones, first became available for clinical consumption in 1962 and was used mainly for urinary tract ...

Establishment of multiplex PCR for detection of genes related to Quinolone resistance

Vietnam Journal of Science, Technology and Engineering, 2018
Background/aims: It has been shown that quinolone resistance arises due to mutations in the quinolone resistance-determining regions of the drug targets.

Genetic markers associated with resistance to beta-lactam and quinolone antimicrobials in non-typhoidal Salmonella isolates from humans and animals in central Ethiopia

Antimicrobial Resistance and Infection Control, 2017
Background Beta-lactam and quinolone antimicrobials are commonly used for treatment of infections caused by non-typhoidal Salmonella (NTS) and other pathogens. Resistance to these classes of antimicrobials has increased significantly in the recent years.
