Systematic Evaluation of Helicobacter pylori Susceptibility to Antibiotics Before First‐Line Treatment: A Cohort Study

United European Gastroenterology Journal, Volume 13, Issue 7, Page 1289-1294, September 2025.
ABSTRACT Background European guidelines recommend that susceptibility tests be routinely performed, even before prescribing first‐line treatment of Helicobacter pylori infection. However, empirical treatments are the rule in France, and susceptibility‐guided treatments are the exception.

Systematic review and meta-analysis of colistin heteroresistance in Klebsiella pneumoniae isolates

BMC Infectious Diseases
Background Antibiotic heteroresistance is a common phenotype observed in a variety of pathogenic bacteria such as K. pneumonia: A subpopulation of cells with a higher MIC than the dominant population is defined as heteroresistance.

Decreased susceptibility to vancomycin and other mechanisms of resistance to antibiotics in Staphylococcus epidermidis as a therapeutic problem in hospital treatment

Scientific Reports, 2023
Multidrug-resistant coagulase-negative staphylococci represent a real therapeutic challenge. The aim of the study was to emphasize the importance of heteroresistance to vancomycin presence in methicillin-resistant strains of S. epidermidis.

Helicobacter pylori Infection in Children Versus Adults, Differences in Management Guidelines: Risks and Benefits of Treatment in Childhood

Helicobacter, Volume 30, Issue 4, July/August 2025.
ABSTRACT Helicobacter pylori infection in children and adults differs in several aspects such as the natural history, prevalence, the clinical presentations and complications, antibiotic resistance rates, treatment options, and the success rates of treatment.

Eravacycline activity against clinical S. aureus isolates from China: in vitro activity, MLST profiles and heteroresistance

BMC Microbiology, 2018
Background Mortality rates for patients with Staphylococcus aureus (S. aureus) infections have improved only modestly in recent decades and S. aureus infections remain a major clinical challenge This study investigated the in vitro antimicrobial activity

Real‐Time PCR Helicobacter pylori Test in Comparison With Culture and Histology for Helicobacter pylori Detection and Identification of Resistance to Clarithromycin: A Single‐Center Real‐Life Study

Helicobacter, Volume 30, Issue 2, March/April 2025.
ABSTRACT Background In our center, RT‐PCR was integrated as a routine method to diagnose Helicobacter pylori due to its higher availability after COVID‐19 pandemics. The objective of this study was to assess the feasibility and performance of systematically performed RT‐PCR for H.

Antimicrobial Heteroresistance: an Emerging Field in Need of Clarity [PDF]

Clinical Microbiology Reviews, 2015
SUMMARY “Heteroresistance” describes a phenomenon where subpopulations of seemingly isogenic bacteria exhibit a range of susceptibilities to a particular antibiotic. Unfortunately, a lack of standard methods to determine heteroresistance has led to inappropriate use of this term.

Real‐Time Assessment of H. pylori Infection to Guide Molecular Antibiotic Resistance Testing: A Combined Endoscopy‐Gastric Juice Analysis Approach

Alimentary Pharmacology &Therapeutics, Volume 61, Issue 3, Page 465-471, February 2025.
Endoscopy combined with intraprocedural gastric juice analysis is highly accurate for Helicobacter pylori detection and, in case of a positive finding, can selectively direct to antibiotic susceptibility testing. Genotypic susceptibility testing using gastric aspirate accurately detects H. pylori resistance to clarithromycin and levofloxacin, with test

Outsmarting Nightmare: Drug Resistance in Acinetobacter baumannii

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Acinetobacter baumannii is a critical nosocomial pathogen recognized by the WHO as a top‐priority threat due to its extensive drug resistance, particularly in carbapenem‐resistant Acinetobacter baumannii (CRAB) strains. According to recent CDC reports, CRAB is one of the most urgent causes of hospital‐acquired infections, driving longer hospital stays,
