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.

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.

Methods to Evaluate Colistin Heteroresistance in Acinetobacter baumannii [PDF]

, 2019
The nosocomial pathogen Acinetobacter baumannii is a growing threat to public health due to its increasing resistance to antibiotics including the last-line polymyxin, colistin. Heteroresistance to colistin has been described in A. baumannii, wherein a resistant subpopulation of cells coexisting with a majority susceptible subpopulation actively grows ...

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

Clinical, Microbiological, and Genetic Characteristics of Heteroresistant Vancomycin-Intermediate Staphylococcus aureus Bacteremia in a Teaching Hospital [PDF]

, 2014
The emergence of vancomycin intermediate Staphylococcus aureus (VISA) and heterogeneous VISA (hVISA) is of major concern worldwide. Our objective was to investigate the prevalence, phenotypic and molecular features of hVISA strains isolated from ...

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,

Impact of heteroresistance on treatment outcomes of people with drug-resistant TB

IJTLD Open
BACKGROUND: Poor treatment outcomes among people with drug-resistant TB (DR-TB) are a major concern. Heteroresistance (presence of susceptible and resistant Mycobacterium tuberculosis in the same sample) has been identified in some people with TB, but ...

Revisiting the Metallo‐β‐Lactamase–Mediated Antibiotic Resistance: Exploring Novel Mechanisms and Therapeutic Strategies

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
β‐Lactam resistance is one of the major health concerns today, primarily due to enzymes called β‐lactamases. Metallo‐β‐lactamases (MβLs) can cleave a wide range of β‐lactam antibiotics, including carbapenems. These enzymes require zinc (Zn) ions to function and can be inhibited by conventional β‐lactamase inhibitors.
