4/4 Huge credit to Sean Stephenson and Walaa Eid, and a special shout-out to @adamrudner.bsky.social for helping us enter the world of bacteriophages! Read our preprint (not yet peer reviewed): www.biorxiv.org/content/10.6...
biorxiv.org
Municipal Wastewater in Ottawa, Canada contains a reservoir of bacteriophages with clinically relevant Escherichia coli and Klebsiella pneumoniae Hosts
The recent rise of antimicrobial resistant bacteria in health care and environmental settings has been detrimental to the feasibility of antibiotic treatments for patients and agricultural application...

3/4 Phage therapy offers a potential treatment approach orthogonal to antibiotics: using bacteria-infecting viruses to kill bacterial targets. Our collection provides a starting point for screening; these isolates’ therapeutic safety and efficacy remain to be tested.

2/4 We found phages in wastewater from a university residence, treatment-plant influent and primary sludge—all without enrichment. We sequenced and biobanked 10 isolates spanning four genera, creating a local resource for further study. All genomes have been deposited in GenBank.

1/4 ✏️🔬 New manuscript posted! A foray into bacteriophages alongside our lab’s main research! Drs. Sean Stephenson and Walaa Eid built this project from scratch, isolating and sequencing 10 phages using clinically relevant bacterial hosts: E. coli O1:K1:H7 and Klebsiella pneumoniae K3.
