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 ...

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...

Our last story is in mBio !(tinyurl.com/h83mh8vy).
Oral bacteria often form mixed species biofilms where aggregation drives interspecies interactions.
Here we investigated Veillonella parvula aggregation with other bacteria and identified molecular actors at the base of such specific interactions!
