Our latest preprint compares the dual-arm nanopore workflow with the respiratory metagenomics protocol currently implemented across the NHS, using clinical samples.

TLDR: Dual-arm protocol provides comparable, if slightly improved performance, at the cost of longer turn-around times and higher sample failure rates and so is not currently suitable for a clinical setting.

As part of the @nhsmetagenomicsnet.bsky.social we have compared the current in-service nanopore metagenomics protocol with ONT's own dual-arm protocol. The results are published in the following preprint:

Happy to share our new AMR resource which has phenotypic AMR (usually MIC data) collected from publications and databases. This is paired with assemblies and annotations

We're excited for users who might train new models, find phenotype/genotype mismatches, or any other use

What an inspiring day! Last week we hosted our second Network Day, bringing together over 120 people. We explored the development of the national pilot metagenomic service, which is improving detection & treatment of respiratory infections. Thank you to all who joined and to our fantastic speakers!

Possibly one of the biggest changes in microbiology has been going on quietly over the past decade. Whilst this remains a diagnostic in development- and we have much to learn about how to use it- it represents a step change in how we manage infections.

@UKHSA latest respiratory surveillance released.

1.flu positivity and hospitalisations rising fast - earlier than last year and exponential growth

2. RSV remains high but looks like it is close to peak - highest rates in children under 5.

3. COVID at low levels and stable.

Impressive.

Key take homes for me.
1) Time to result still long - addressable but a barrier currently.
2) 10% contamination.
3) Despite using cutting edge tests a "causative" organism found in only 15%.
