WebNov 29, 2013 · A significant difference in the phagocytosis of planktonic bacteria versus biofilm bacteria by human macrophages was observed using several techniques (e.g., flow cytometry, CFU count and confocal microscopy). Moreover, our findings indicated that human macrophages prefer planktonic bacteria to biofilm. Dispersal of cells from the biofilm colony is an essential stage of the biofilm life cycle. Dispersal enables biofilms to spread and colonize new surfaces. Enzymes that degrade the biofilm extracellular matrix, such as dispersin B and deoxyribonuclease, may contribute to biofilm dispersal. Enzymes that degrade the biofilm matrix may be useful as anti-biofilm agents. Evidence has shown t…
