WitrynaThis enabled us to track bacterial flagella during biofilm maturation. Live flagella imaging revealed the presence and synthesis of flagella throughout the biofilm life cycle. To study the possible role of flagella in a biofilm, we produced a flagella knockout strain and compared its biofilm to that of the wild-type strain. WitrynaAt least one degenerate flagellar system from Brucella melitensis still has a cryptic role in infection, even though it is no longer capable of mediating motility [14]. More recently, flagellar-related genes have been detected in the genome of Myxococcus xanthus, a soil bacteria that uses gliding rather than flagellar motility [5]. In addition, Witryna9 wrz 2024 · Flagella Mutants Produce More Thick and Dense Biofilms. To explore the role of flagella on biofilm maturation, CLSM was used to directly observe biofilms that had been allowed to form for 48 h. The wild-type biofilms were twice as thick as the ΔflgE biofilms and had a looser inner structure than the mutant biofilms (Figures 5A–D). hilbert college hamburg new york
