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 ...

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

PNA-FISH as a new diagnostic method for the determination of clarithromycin resistance of Helicobacter pylori

BMC Microbiology, 2011
Background Triple therapy is the gold standard treatment for Helicobacter pylori eradication from the human stomach, but increased resistance to clarithromycin became the main factor of treatment failure.

Exploring the Molecular Mechanisms of Macrolide Resistance in Laboratory Mutant Helicobacter pylori

Antibiotics
Resistance to clarithromycin, a macrolide antibiotic used in the first-line treatment of Helicobacter pylori infection, is the most important cause of treatment failure. Although most cases of clarithromycin resistance in H.
