Helicobacter pylori resistance to metronidazole and clarithromycin in Ireland

European Journal of Gastroenterology & Hepatology, 2010
Helicobacter pylori eradication rates have fallen considerably in recent years. Antibiotic resistance is thought to be rising.To examine the levels of resistance to metronidazole (MTZ) and clarithromycin (CLA) in H. pylori, isolates were taken in a reference centre in Ireland from 2007 to 2008 and were compared to a similar cohort from a study in 1997 ...

Clarithromycin-Resistant Genotypes and Eradication of Helicobacter pylori

Annals of Internal Medicine, 2006
Three point mutations (A2143G, A2142G, and A2142C) have been involved in Helicobacter pylori clarithromycin resistance.To compare the eradication rates among the different point mutations and the efficacy of triple therapy and a sequential regimen according to genotypic resistance.Post hoc subgroup study from a multicenter, randomized trial.Two ...

The Helicobacter pylori Resistance Rate to Clarithromycin in Iran

Microbial Drug Resistance, 2014
Background: Clarithromycin is the most commonly suggested antibiotic in Helicobacter pylori eradication regimens. Increasing antibiotic resistance rate to clarithromycin is the main reason for therapeutic failure.

Prevalences of metronidazole‐ and clarithromycin‐resistant Helicobacter pylori isolates in Shanghai and molecular mechanism of resistance to clarithromycin

Chinese Journal of Digestive Diseases, 2001
OBJECTIVE: To investigate the prevalences of metronidazole‐ and clarithromycin‐resistant Helicobacter pylori over the period from 1995 to 1999 in Shanghai, and the molecular mechanism of resistance to clarithromycin. METHODS: A total of 150 H. pylori strains were randomly selected from the isolates collected in 1995, 1997 and 1999, and tested for ...

[Genotypic homogeneity and susceptibility to clarithromycin for clarithromycin-resistant Helicobacter pylori strains].

Zhonghua yi xue za zhi, 2010
To investigate the mixed infection of clarithromycin susceptibility and genotype of Helicobacter pylori resistant strains.Ten single colonies were picked randomly from each of 16 resistant strains. Genomic DNA was prepared from single colony isolates and their parental clarithromycin-resistant strains by the hexadecyltrimethylammonium bromide (CTAB ...

The bactericidal activity of clarithromycin versus ampicillin alone and in combination with omeprazole and/or bismuth against clarithromycin-susceptible and clarithromycin-resistant strains of Helicobacter pylori

Diagnostic Microbiology and Infectious Disease, 1998
We evaluated the in vitro bactericidal effect of clarithromycin versus ampicillin alone and in combination against clarithromycin-sensitive and clarithromycin-resistant strains of Helicobacter pylori. No combination containing clarithromycin achieved complete bactericidal effect against clarithromycin-resistant strains. Complete bactericidal effect was

Comparison of Clarithromycin-sensitive and Clarithromycin-resistant Mycobacterium avium Strains Isolated from AIDS Patients during Therapy Regimens including Clarithromycin

Journal of Infection, 2000
Sixteen Mycobacterium avium strains were isolated from the blood of eight AIDS patients over a period of months. All the patients were on combination therapies including clarithromycin, and all had treatment failure and relapses of M.avium bacteremia. Paired clarithromycin-sensitive and resistant M.avium strains isolated at the beginning of treatment ...

Genotypic characterization of clarithromycin-resistant Helicobacter pylori strains.

The new microbiologica, 2002
Helicobacterpylori (Hp) resistance to clarithromycin, one of the antibiotics most used to eradicate infection, is connected with the presence of a point mutation on the level of adenine at position 2143 or 2144 of 23S rRNA.The aim of the study is to evaluate of the presence of these mutation vs control clarithromycin resistant Hp strains present in ...
