Article Synopsis
- Helicobacter pylori infects over half of the global population and is the leading cause of chronic gastritis, which can result in serious conditions like peptic ulcers and stomach cancer, particularly in Colombia where infection rates exceed 80%.
- A study in Pereira, Colombia analyzed five H. pylori isolates from patients with different gastritis severities, revealing that all were resistant to at least one antimicrobial and had distinct genetic traits associated with virulence.
- The findings underscore the diversity in antimicrobial resistance and genome characteristics of H. pylori in gastritis cases, which can inform more effective treatment strategies tailored to specific infections.
Antimicrobial susceptibility of clinical isolates and its eradication by standard triple therapy: a study in west central region of Colombia.
Microbiol Spectr
August 2024
The aim of the present study was first to isolate from gastric biopsy specimens and to test their antibiotic susceptibility. Second, it was to evaluate the efficacy of the standard triple therapy from patients of the west central region of Colombia. positive patients received standard triple therapy with proton pump inhibitor (PPI) (40 mg b.

- This study focuses on Pseudomonas aeruginosa Sequence Type 235 in Colombia, highlighting its ability to acquire resistance genes, particularly those related to carbapenem resistance, which poses a significant infection threat in healthcare settings.
- In a study conducted across five ICUs, 58 P. aeruginosa isolates were collected, with nearly half showing carbapenem resistance; molecular analysis revealed specific genes associated with resistance within certain isolates.
- The research uncovers a novel chromosomal feature involving a double insertion of Tn4401b in a new genomic island (PAGI-17), showcasing the organism's genomic adaptability and complexity in how it spreads antibiotic resistance.
