Metagenomic editing of commensal bacteria in vivo using CRISPR-associated transposases
Although metagenomic sequencing has revealed a rich microbial biodiversity in the mammalian gut, methods to genetically alter specific species in the microbiome are highly limited. Here, we introduce ...

✨I am thrilled to announce that my #ERCStG project will be funded by @erc.europa.eu. It explores how predatory bacteria interact with bacteria, which they invade and kill 🔬. I am very grateful to the ERC, the panel, reviewers, mentors, collaborators and colleagues! 🙏

Bacterial #QuorumSensing is often assumed to follow a strict hierarchy. @brownlab.bsky.social &co find that #Pseudomonas aeruginosa instead uses a reciprocal, cooperative system that enhances responsiveness to population density & environmental changes @plosbiology.org 🧪 plos.io/3I7DhRG
The las and rhl QS systems have a reciprocal, synergistic, and unequal relationship. Top: Single-signal models demonstrate that the summed effects of single signals (3 oxo C12 HSL alone, red; C4 HSL alone, orange) cannot account for the maximal expression of lasI or rhlI. The upper green, flat surfaces in the plots indicate the maximum mean expression level measured across all combinations of signal concentrations while the lower semi-transparent surfaces mark the sum of single signal effects. The plotted points represent observed expression levels when C4 HSL is withheld (red) and when 3 oxo C12 HSL is withheld (yellow). Lines indicate the model predictions. Bottom: Multi-signal non-linear models capture the synergistic effects of both signals and match observed expression levels. Model estimates are shown as grid lines. Horizontal bars show the mean value of expression observed at each combination of signal concentrations. Lines extend from these mean values to the relevant grid point for clarity. Right: Data show that relationship of the las and rhl systems is reciprocal, and the multi-signal model quantifies the strength of those interactions. In particular, it reveals the contribution of both signals to the maximum fold-change in expression of both synthases. The charts in this panel summarize the contribution of 3 oxo C12 HSL (red), C4 HSL (yellow), and the synergistic combination of both (orange).

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬?

In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments!

Predatory bacteria kill and eat other bacteria. Their deadly actions come in many flavors, often via direct physical contact between predator &
prey 🧛
