Molecular Detection of Antibiotic-Resistant Helicobacter pylori

Antimicrobial susceptibility testing (AST)Antimicrobial susceptibility testing (AST) for H. pylori (H. pylori) is essential to accurately assess the prevalence of antibiotic resistanceAntibiotic resistance in each population. Antibiotic resistanceAntibiotic resistance rates form the basis of local guidelines for H. pylori (H. pylori) treatmentTreatment and AST Antimicrobial susceptibility testing (AST) may also be used as a personalized medicine approach to tailor therapy. This chapter provides an update on global antibiotic resistanceAntibiotic resistance rates and describes molecular mechanisms that confer H. pylori antibiotic resistanceAntibiotic resistance. An overview on the advantages and limitations of molecular AST Antimicrobial susceptibility testing (AST) using both invasive and noninvasive approaches is also provided.
