Mucoid or SCV clinical isolates do not form specific biofilm structures. a Examples of biofilm phenotypes of selected mucoid and SCV morphotypes visualized in an easy-3D projection (48 h-old biofilms stained with the BacLight™ Viability-Kit) and b principal component analysis (PCA) representation of the biofilm phenotype of 113 clinical isolates. Seven biofilm parameters were taken into account. SCV are depicted in red, mucoid in pink, and others in green
