Cet article décrit une méthode pour séparer les souches bactériennes en fonction de leurs quantités de capsule en utilisant un gradient de densité discontinu. La technique permet l'analyse de bibliothèques de mutants transposons bactériens, facilitant les études ultérieures de la génétique bactérienne.
This method enables rapid phenotypic sorting of bacterial mutants based on capsule expression, supporting target validation in antimicrobial discovery. By isolating strains with altered surface polysaccharides, it facilitates mechanistic de-risking of virulence factors and host-pathogen interaction studies. The approach improves predictive confidence in early-stage target prioritization by linking genotype to capsule-mediated phenotypes.
The method fits within early discovery workflows, enabling hit validation from transposon screens before lead identification efforts.
