New in Solu: HGT detection in Pulse and transmission reconstruction

November 2025

🧬 Horizontal gene transfer events in Pulse

Last month, we introduced Solu Pulse, the center for real-time genomic epidemiology. Since then, we’ve been listening closely to feedback from our pilot users to make Pulse even smarter.

Pulse can now detect potential horizontal gene transfer (HGT) events, highlighting cases where antimicrobial resistance genes may be spreading between organisms or genetically distant bacteria.

Curious why HGT matters? Read our recent post explaining why horizontal spread is often overlooked in genomic surveillance.

Access to Pulse is still limited, but you can sign up for early access anytime.

Transmission reconstruction

Earlier, we introduced reconstructed transmission trees as an opt-in feature. Based on user feedback, this analysis is now available directly in the cluster view.

The timeline reconstructs the likely order of transmission events using both genetic distances and sample collection dates, helping you interpret how a cluster may have unfolded over time.

The transmission timelines are currently available for Genomic Surveillance and Large Scale Surveillance plans. Let us know if you’re interested in upgrading!

AMR badges in phylogenetic trees

You can now display antimicrobial resistance badges directly inside the phylogenetic tree.

This makes it easier to spot clusters enriched for key AMR traits, and quickly pinpoint samples that may require closer attention.
