TLDR
A web server providing a convenient way of identifying acquired antimicrobial resistance genes in completely sequenced isolates was created, and the method was evaluated on WGS chromosomes and plasmids of 30 isolates.Abstract:
Objectives
Identification of antimicrobial resistance genes is important for understanding the underlying mechanisms and the epidemiology of antimicrobial resistance. As the costs of whole-genome sequencing (WGS) continue to decline, it becomes increasingly available in routine diagnostic laboratories and is anticipated to substitute traditional methods for resistance gene identification. Thus, the current challenge is to extract the relevant information from the large amount of generated data.read more

Long-distance transmission of pathogenic Vibrio species by migratory waterbirds: a potential threat to the public health.
TL;DR: The results provide the first evidence of direct transmission from mollusks to waterbirds and confirm that waterbirds act as disseminating vehicles of waterborne pathogens.

TL;DR: Overall, the Indian isolates were resistant to more antibiotics, with some of those isolates being multi-drug resistant, and large number of acquired resistance genes, greater changes to MMR genes, and a larger pan genome as well as increased overall genetic variation are investigated.

TL;DR: While there is strong evidence for recent farm-to-farm transmission of 3 GC-R strains and plasmids—including one epidemic plasmid that has a remarkable capacity to be transmitted—there was no evidence that 3GC-R E. coli found on study farms had a significant impact on circulating 3GC.

TL;DR: ResCap, the first targeted sequence capture specifically developed to analyse resistomes, enhances the sensitivity and specificity of available metagenomic methods to analyse antibiotic resistance in complex populations, enables the analysis of other genes related to antimicrobial resistance and opens the possibility to accurately study other complex microbial systems.
Journal ArticleDOI
Tracking the environmental dissemination of carbapenem-resistant Klebsiella pneumoniae using whole genome sequencing.
TL;DR: This study highlights the dissemination of 'high' importance and novel ST CRKP from hospital wastewater to waterbodies, particularly in the African context where a sizable number of people still rely on direct water resources for household use, including drinking.

TL;DR: Attention is paid to mobile genetic elements such as plasmids, transposons, and integrons, which are associated with AR genes, and involved in the dispersal of antimicrobial determinants between different bacteria.

TL;DR: The results strongly suggest that livestock-associated MRSA CC398 originated in humans as MSSA, which appears to have undergone a rapid radiation in conjunction with the jump from humans to livestock, where it subsequently acquired tetracycline and methicillin resistance.
Journal ArticleDOI
Comparison of antimicrobial resistance phenotypes and resistance genes in Enterococcus faecalis and Enterococcus faecium from humans in the community, broilers, and pigs in Denmark.
TL;DR: Differences in the occurrence of resistance and tetracycline resistance genes were observed among isolates from the different sources, however, similar resistance patterns and resistant genes were detected frequently indicating that transmission of resistant enterococci or resistance genes takes place between humans, broilers, and pigs.
