Objectives: Mutations in the quinolone resistance–determining regions (QRDRs) of the
topoisomerase genes are considered to be a primary mechanism of quinolone and …

Over the past few years, the number of Shigella strains resistant to nalidixic acid has
increased and has made the selection of effective antimicrobial therapy more difficult. The …

Methods Seventy-three clinical isolates were collected. Susceptibility tests of pipemidic
adcid (PI), ofloxacin (OFL), norfloxacin (NOR), and ciprofloxacin (CIP) were performed in all …

Aims: This study was carried out to find the prevalence of various plasmid‐mediated
quinolone‐resistant (PMQR) determinants among the quinolone‐resistant clinical isolates of …

Purpose Fluoroquinolone-resistant Shigella is considered a serious public health problem
and has been put on the WHO global priority list of antibiotic-resistant bacteria. This study …

Fluoroquinolone (FQ) resistance in clinical isolates of Shigella species has been increasing
reported in recent years. This study was carried out to find the mutations within the …

In this research 26 Shigella isolates were examined by PCR and direct nucleotide
sequencing for genetic alterations in the quinolone-resistance determining regions …

A total of 293 Shigella isolates were isolated from patients with diarrhoea in four villages of
Henan, China. This study investigated the prevalence of the plasmid-mediated quinolone …

The increased Salmonella resistance to quinolones and fluoroquinolones is a public health
concern in the Southeast Asian region. The objective of this study is to develop a high …

To understand the genetic basis of high drug resistance in Shigella, 95 clinical isolates of
Shigella spp.(2001–2010) were obtained from the Infectious Diseases Hospital, Kolkata …
