AI Article Synopsis
- The Eurasian woodcock migrates to find better breeding and wintering grounds, particularly moving from northeastern Europe to the Mediterranean in autumn.
- The study aimed to investigate if these birds could carry antibiotic resistance genes (ARGs) during their migration, focusing on beta-lactam resistance.
- While no phenotypic resistance was found in the tested strains against 13 antibiotics, certain isolates were identified as carrying specific resistance genes, highlighting the need to monitor antimicrobial resistance in migratory species.
Article Abstract
The Eurasian woodcock () belongs to those bird species that make systematic migratory flights in spring and autumn in search of favorable breeding and wintering areas. These specimens arrive in the Mediterranean Area from northeastern European countries during the autumn season. The purpose of this study was to assess whether woodcocks can carry antibiotic resistance genes (ARGs) along their migratory routes. Although the role of migratory birds in the spread of some zoonotic diseases (of viral and bacterial etiology) has been elucidated, the role of these animals in the spread of antibiotic resistance has not yet been clarified. In this study, we analyzed the presence of beta-lactam antibiotic resistance genes. The study was conducted on 69 strains from 60 cloacal swabs belonging to an equal number of animals shot during the 2022-2023 hunting season in Sicily, Italy. An antibiogram was performed on all strains using the microdilution method (MIC) and beta-lactam resistance genes were investigated. The strains tested showed no phenotypic resistance to any of the 13 antibiotics tested; however, four isolates of and three of were found to carry the , , and genes. Our results confirm the importance of monitoring antimicrobial resistance among migratory animals capable of long-distance bacteria spread.

Acta Orthop Belg
December 2024
Chryseobacterium indologenes is a rare human pathogen which is nowadays considered an emerging fearsome organism because of its upcoming antibiotic resistance. We present a quite unique case of a multi drug resistant C. indologenes surgical wound infection in a patient submitted to cannulated screw fixation of a displaced medial malleolus fracture.

The cytoplasmic membrane of bacteria is composed of a phospholipid bilayer made up of a diverse set of lipids. Phosphatidylglycerol (PG) is one of the principal constituents and its production is essential for growth in many bacteria. All the enzymes required for PG biogenesis in have been identified and characterized decades ago.

Protozoa, as primary predators of soil bacteria, represent an overlooked natural driver in the dissemination of antibiotic resistance genes. However, the effects of protozoan predation on antibiotic resistance genes dissemination at the community level, along with the underlying mechanisms, remain unclear. Here we used fluorescence-activated cell sorting, qPCR, combined with metagenomics and reverse transcription quantitative PCR, to unveil how protozoa (Colpoda steinii and Acanthamoeba castellanii) influence the plasmid-mediated transfer of antibiotic resistance genes to soil microbial communities.

Introduction: The methicillin-resistant Staphylococcus aureus (MRSA) genome varies by geographical location. This study aims to determine the genomic characteristics of MRSA using whole-genome sequencing (WGS) data from medical centers in Mexico and to explore the associations between antimicrobial resistance genes and virulence factors.
Methods: This study included 27 clinical isolates collected from sterile sites at eight centers in Mexico in 2022 and 2023.

Introduction: The global prevalence of antimicrobial resistance transcends geographical and economic boundaries, affecting populations worldwide. Excessive and incorrect use of antibiotics encourages antimicrobial resistance which leads to complex treatment strategies for infectious diseases and possible failure of treatment. The incorrect and unnecessary prescribing of antibiotics places a burden on healthcare costs and thus, antimicrobial resistance is evident globally as a major public health concern.
