Clarithromycin Resistance in Helicobacter Pylori

Central Asian Journal of Medical Sciences, 2016
Objectives: Eradication rates of Helicobacter pylori with standard triple therapy are disappointing in studies from several countries. The main reason for failure was found to be bacterial resistance to one of the most commonly used antibiotics ...

Inducible and Acquired Clarithromycin Resistance in the Mycobacterium abscessus Complex.

PLoS ONE, 2015
PurposeClarithromycin was considered the cornerstone for the treatment of Mycobacterium abscessus complex infections. Genetic resistance mechanisms have been described and many experts propose amikacin as an alternative.

Molecular Characterization of Clarithromycin Resistance in Helicobacter pylori Strains. [PDF]

Turk J Gastroenterol, 2023
Background: The purpose of this study was to determine the antimicrobial status of stocked clinical Helicobacter pylori isolates by using antibiotic gradient test and subsequently identify the mutations that cause clarithromycin resistance by DNA sequencing.

Genetic basis of clarithromycin resistance in <i>Bacillus anthracis</i>. [PDF]

Microbiol Spectr
ABSTRACT The high-consequence pathogen Bacillus anthracis causes human anthrax and often results in lethal infections without the rapid administration of effective antimicrobial treatment.

Early genetic diagnosis of clarithromycin resistance in Helicobacter pylori. [PDF]

World J Gastroenterol, 2021
The drug resistance rate of clinical Helicobacter pylori (H. pylori) isolates has increased. However, the mechanism of drug resistance remains unclear. In this study, drug-resistant H. pylori strains were isolated from different areas and different populations of Chinese for genomic analysis.To investigate drug-resistant genes in H. pylori and find the

Mycobacterium avium strains resistant to clarithromycin and azithromycin [PDF]

Antimicrobial Agents and Chemotherapy, 1993
Mycobacterium avium strains susceptible to clarithromycin and azithromycin contain mutants resistant to these macrolides with a frequency of 1.1 x 10(-10) to 1.2 x 10(-6). Cross-resistance between clarithromycin and azithromycin was demonstrated with mutants selected in the laboratory as well as with resistant strains isolated from patients.

Selection of Resistance to Clarithromycin in Mycobacterium abscessus Subspecies [PDF]

Antimicrobial Agents and Chemotherapy, 2017
ABSTRACT Mycobacterium abscessus is an emerging pathogen against which clarithromycin is the main drug used. Clinical failures are commonly observed and were first attributed to acquired mutations in rrl encoding 23S rRNA but were then attributed to the intrinsic production of the ...

A Mechanism of Clarithromycin Resistance in Helicobacter pylori

Journal of the Japanese Association for Infectious Diseases, 1998
The aim of this study was to elucidate the mechanism of clarithromycin (CAM) resistance in laboratory strains and clinical isolates of Helicobacter pylori. The CAM resistance in laboratory strains was induced in vitro by CAM exposure. The majority of CAM-resistant strains were highly resistant to CAM (MICs > 100 micrograms/ml).

Primary resistance to clarithromycin, metronidazole and amoxicillin of Helicobacter pylori isolated from Tunisian patients with peptic ulcers and gastritis: a prospective multicentre study

Annals of Clinical Microbiology and Antimicrobials, 2010
Background The frequency of primary resistance to antibiotics in H. pylori isolates is increasing worldwide. In Tunisia, there are limited data regarding the pattern of H. pylori antibiotic primary resistance. Aim To evaluate the primary resistance of H.

Characteristics of Helicobacter pylori antibiotic resistance: data from four different populations

Antimicrobial Resistance and Infection Control, 2019
Aims To describe the characteristics of Helicobacter pylori (H. pylori) antibiotic resistance in clinical isolates from four populations. Methods In total, 1463 H. pylori strains were examined for antibiotic resistance.
