Saludos.
En kudoz se encontró twitching, más no relacionado con motilidad.
Si la pregunta no es el caso, disculpas de antemano.
Gracias por su trabajo.

Biofilm Matrix and Its Regulation in Pseudomonas aeruginosa

Flagella mediate swimming and swarming motility of P. aeruginosa. It can also act as an adhesin and play critical roles in the initial cell-to-surface interactions [60]. T4P is a linear actuator critical for twitching motility that involves an extension-grip-retraction mechanism [61]. T4P plays important roles in microcolony formation of P. aeruginosa biofilms by forming typical mushroom caps [60]. As mentioned above, T4P-driven bacterial motilities can help to form Psl fiber matrix [25]. Another group, however, drew the conclusion that flagella and pili are not required for the initial attachment or biofilm formation [62], indicating that flagella- and pili-mediated biofilm formation could be conditional and nutritional. Recently, another newly identified adhesin named CdrA was demonstrated to be a key protein functioning as a structural component of P. aeruginosa EPS matrix [63]. This adhesin could directly interact with Psl polysaccharide to mediate bacterial auto-aggregation and increase
biofilm stability.
