Helicobacter pylori Primary and Secondary Genotypic Resistance to Clarithromycin and Levofloxacin Detection in Stools: A 4-Year Scenario in Southern Italy

Antibiotics, 2020
Antibiotic resistance has become an emerging problem for treating Helicobacter pylori (H. pylori) infection. Clarithromycin and levofloxacin are two key antibiotics used for its eradication. Therefore, we reviewed our experience with genotypic resistance

Genotypic and Phenotypic Resistance to Clarithromycin in Helicobacter pylori Strains [PDF]

Journal of Clinical Medicine, 2020
Background: The increasing prevalence of antimicrobial resistance, together with the lack of novel treatment options, negatively affects successful eradication of Helicobacter pylori. The aim of this study was to investigate genetic mutations in the 23S rRNA genes, which is associated with clarithromycin resistance, and to determine the clinical impact

Lack of association between rrl and erm(41) mutations and clarithromycin resistance in Mycobacterium abscessus complex [PDF]

Memorias do Instituto Oswaldo Cruz, 2017
BACKGROUND Mycobacterium abscessus complex (MABC) includes species with high resistance rates among mycobacterial pathogens. In fact, MABC infections may not respond to clarithromycin treatment, which has historically been very effective against MABC ...

Primary clarithromycin resistance in Helicobacter pylori: the Multicentric Italian Clarithromycin Resistance Observational (MICRO) study.

Journal of gastrointestinal and liver diseases : JGLD, 2011
Primary clarithromycin resistance markedly reduces Helicobacter pylori eradication rate following standard therapies. Prevalence of primary clarithromycin resistance in H. pylori is increasing, and three point mutations are mainly involved. AIM. To assess both the prevalence of primary clarithromycin resistance in Italy, and the distribution of the ...
