evaluation of antibiotic resistance to fluoroquinolones and third generation cephalosporines in iranian clinical isolates of salmonella spp.

Evaluation of Antibiotic Resistance to Fluoroquinolones and Third Generation Cephalosporines in Iranian Clinical Isolates of Salmonella spp.

Salmonella enterica serotypes are one of the most important food borne pathogens and significant public health concerns around the world in humans and other animal species. A total of eighty three epidemiologically unrelated clinical isolates of Salmonella enterica serovars were subjected to antimicrobial susceptibility testing. Eleven isolates (13.1%) which were resistant to at least 4 groups ...

Evaluation of Resistance to Fluoroquinolones and Its Relationship whit parC Gene Mutation in Klebsiella pneumoniae Clinical Isolates

Background & Objective: Klebsiella pneumoniae has received attention due to a wide range of diseases and antibiotic resistance.The resistance to fluoroquinolones in gram-negative bacteria is often due to chromosomal mutations in the gyr and par genes. This research aimed at investigating the pattern of fluoroquinolone resistance and its relation with a mutation in the parC gene among clinical i...

Antibiotic resistance in clinical and environmental isolates of Aeromonas spp.

Contribution of different mechanisms to the resistance to fluoroquinolones in clinical isolates of Salmonella enterica.

OBJECTIVES To study the potential factors include gene mutation, efflux pump and alteration of permeability associated with quinolone-resistance of Salmonella enterica strains isolated from patients with acute gastroenteritis and to evaluate the degree of synergistic activity of efflux pump inhibitors when combined with ciprofloxacin against resistant isolates. METHODS Antimicrobial resistanc...

Evaluation of Antibiotic Resistance Patterns of Clinical Klebsiella pneumoniae Isolates from Educational Hospitals in Zahedan, Iran

ABSTRACT Background and Objectives: The resistance of gram-negative bacteria to antibiotics has become a serious problem, which imposes a significant increase in treatment costs. Klebsiella pneumoniae is an important nosocomial pathogen from the Enterobacteriaceae family. The aim of this study was to investigate the frequency and pattern of antibiotic resistance in K. pneumoniae strains isolat...

an investigation into iranian teachers consistency and bias in evaluation of students writings

while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
