Surface Motility Clause Samples

Surface Motility. Bacteria colonize and persist on surfaces using different behaviors. Bacterial populations can remain sessile, form aggregates and secrete an exopolysaccharide matrix that leads to the formation of multicellular communities known as biofilms (93, 94). Alternatively, bacteria can become motile and disseminate from the initial point of contact to discover new and perhaps more favorable environments. Various forms of motility are utilized by different bacteria to colonize surfaces. Some forms of motility do not require the presence of flagella (twitching, gliding, and sliding) while others do (swimming and swarming) (95).
