Quantification and categorisation of biofilms: (a) Categorisation of biofilm formed by all collected samples (n = 41) where majority of samples form strong biofilm, (b) Quantification of biofilm formed by selected isolates (n = 5) and combinations (n = 6), the combinations form significantly stronger and adherent biofilm as compared to individual isolates and combinations containing Ct form stronger biofilm as compared to combinations containing Ca, except the combinations containing Pa as the partner. The statistical analysis and graphs were prepared using GraphPad Prism 10, where * - p < 0.05; ** - p < 0.01, *** - p < 0.001, **** - p < 0.0001, and ns indicates p > 0.05.
