📝New preprint! #MicroSky
🕰️We chart the full, synchronized lifecycle of a predatory bacterium using Hi-C, RNA-seq, ChIP-seq & microscopy.
🧬We uncover dramatic shifts in nucleoid architecture & transcription, tightly coordinated with predation.

Dynamics and interplay of gene expression and chromosome organization across a predatory lifecycle
The obligate predatory bacterium Bdellovibrio bacteriovorus alternates between a motile attack phase and a growth phase inside another bacterium, during which it undergoes multiple rounds of DNA repli...

How complex functions, with important physiological and evolutionary impacts get repeatedly and efficiently transferred across genomes?
That’s what we explored using one of the fastest-evolving loci in Bacteria: the capsule locus.

Serotype swapping in Klebsiella spp. by plug-and-play
Understanding how complex, multi-gene systems evolve and function across genetic backgrounds is a central question in molecular evolution. While such systems often impose costs through epistatic inter...

Delighted to share our recently published work!
Ever wondered how Klebsiella (and others) deals with capsule production’s costs ?

Phenotypic heterogeneity of capsule production across opportunistic pathogens | mBio
The polysaccharidic capsule is present in ~50% of species across the bacterial phylogeny, including all ESKAPE microorganisms, the six most significant multidrug-resistant (MDR) nosocomial pathogens. It is also an important virulence factor and a major ...
