Biofilm formation and bacterial mobility can be seen as the outcome of specialised cell differentiation pathways. Biofilm formation involves subsequent cellular changes at the morphological and physiological levels resulting in bacterial populations with multiple phenotypes.4,30,31 Furthermore, bacteria living in biofilm communities are present in different developmental stages (at least four defined stages) as has been observed in Cryptoccocus, Pseudomonas, Staphylococcus, Xanthomonas, etc.32–37
