Metagenome-Assembled Genomes of Pig Fecal Samples in Nine European Countries: Insights into Antibiotic Resistance Genes and Viruses.

Gut microbiota plays a crucial role in the health and productivity of pigs. However, the spread of antibiotic resistance genes (ARGs) and viruses within the pig intestinal microbiota poses significant threats to animal and public health. This study utilized 181 pig samples from nine European countries and employed metagenomic assembly methods to investigate the dynamics and distribution of ARGs and viruses within the pig intestinal microbiota, aiming to observing their associations with potential bacterial hosts.

Background: Glycopeptide antibiotics (GPAs) are a very successful class of clinically relevant antibacterials, used to treat severe infections caused by Gram-positive pathogens, e.g., multidrug resistant and methicillin-resistant staphylococci.

Article Synopsis
- Antibiotic resistance genes (ARGs) from gut microbiota pose significant health risks and can be influenced by non-antibiotic factors like disease states, particularly in cases of cerebral ischemia-reperfusion injury (I/R) which is common in stroke patients.
- Changes in the gut antibiotic resistome during I/R show an increase in tetracycline ARGs while other types, like aminoglycoside and glycopeptide ARGs, decrease, suggesting a shift in microbial resistance profiles.
- The study identifies specific ARG hosts and pathways influenced by I/R, highlighting the increase in multidrug resistance genes and various biosynthetic processes in gut microbiota, providing potential targets for health interventions.
Epidemiological Profile of Bacterial Infections in Burn Patients Over a Five-Year Period.
Cureus
November 2024
Bacteriology Laboratory, Faculty of Medicine and Pharmacy, Mohammed V Military Training Hospital, Mohammed V University, Rabat, MAR.
Introduction: Burn patients are highly susceptible to bacterial infections, which significantly increase morbidity and mortality. Destruction of skin barriers following burns creates an ideal environment for tissue colonization by pathogenic microorganisms.
Objectives: The aim of our study is to establish the epidemiological profile of bacterial infections in burn patients hospitalized in the Burns and Plastic Surgery Department of the Mohamed V Military Teaching Hospital (HMIMV) in Rabat and to describe their sensitivity to antibiotics.
Swab Testing to Optimize Pneumonia treatment with empiric Vancomycin (STOP-Vanc): study protocol for a randomized controlled trial.
Trials
December 2024
Division of Infectious Diseases, Department of Medicine, Vanderbilt University Medical Center, Nashville, TN, USA.
Background: Vancomycin, an antibiotic with activity against methicillin-resistant Staphylococcus aureus (MRSA), is frequently included in empiric treatment for community-acquired pneumonia (CAP) despite the fact that MRSA is rarely implicated in CAP. Conducting polymerase chain reaction (PCR) testing on nasal swabs to identify the presence of MRSA colonization has been proposed as an antimicrobial stewardship intervention to reduce the use of vancomycin. Observational studies have shown reductions in vancomycin use after implementation of MRSA colonization testing, and this approach has been adopted by CAP guidelines.
