Abstract
Production of a significatively higher biofilm biomass and higher swarming motility by CF strains vs NCF strains o Possible correlation between swarming motility and biofilm production like described for Pa in Shrout and al., 2006 8 ➢ Strong expression of virulence factor (swimming motility) by NCF strains compared with CF strains o Confirmation of the results obtained by Filipic et al., 2017 5 ➢ Distinct competitive abilities observed for Ax CF versus NCF strains o Competition affected major pathophysiological traits of Pa including production of virulence factors Does Achromobacter xylosoxidans have specific characteristics that could contribute to its emergence in Cystic Fibrosis ?
