Why can a bacterial lineage spread widely without becoming globally dominant? Dr Mehrad Hamidian takes us behind the scenes of their latest publication on the ST3 subtype of Acinetobacter baumannii in Microbial Genomics. Read the full blog here🔗 microb.io/4gQ4lnb

Microbial interactions as key players shaping the emergence and spread of de novo resistance mutations
Antibiotic resistance and the microbiome are two of the most prominent and highly active research areas currently in microbiology. However, these studies are commonly siloed. Research into antibiotic ...

Variations in plasmid transfer in Acinetobacter baumannii: insights from epigenetics, strain properties, and experimental conditions | Microbiology Spectrum
Plasmid-mediated gene transfer is one of the major drivers of antibiotic resistance in Acinetobacter baumannii; however, plasmid transfer protocols remain inconsistent and strain-dependent. By assessi...

Just published in JAC! We characterised the genomic features of the multi-resistant A. baumannii global clone 1 reference strain RUH875 — one of the earliest known isolates recovered in 1984 and an important genome for tracing the evolution of AMR in Ab. academic.oup.com/jac/article/... #AMR

New pre-print!!! What types of genes end up on plasmids and why? The take home message of this paper is that beneficial genes move from plasmids to chromosome, causing the ecological value of plasmids to decay over time. www.biorxiv.org/content/10.1...

Chromosomal capture of beneficial genes drives plasmids towards ecological redundancy
Plasmids are a ubiquitous feature of bacterial genomes, but the evolutionary forces driving genes to become associated with plasmids are poorly understood. To address this problem, we compared the fit...

New year, new assemblies! I'm excited to announce Autocycler, my new tool for consensus assembly of long-read bacterial genomes! It's the successor to Trycycler, designed to be faster and less reliant on user intervention. Check it out: github.com/rrwick/Autoc... (1/5)
