Mechanisms of bacterial host-to-host transmission | Microbiology and Molecular Biology Reviews SUMMARYBacterial pathogens must navigate complex host environments to thrive, replicate, and ultimately transmit to new hosts. Effective transmission is critical for pathogen propagation and often requires overcoming host defenses and exploiting ...

Our comprehensive review on bacterial transmission is out today in MMBR @asm.org, which took us ~2 years to put together. Thanks to Kim Walker @drwalkermsbanta.bsky.social and my graduate student, Giovanna Hernandez, for all the hard work they put into this review!

First post! Our study in Nature Comms showing the importance of the T6SS of Klebsiella pneumoniae in gut colonization. We combined tn-seq with metagenomics and identified new microbiota targets and T6SS regulators.
Major thanks to Kim walker and Virginia Miller
