Pseudomonas aeruginosa swarmer cells move quickly from the colony center as multicellular rafts. Then, they pause and undertake several dedifferentiations.

These colony morphology variants can also be isolated from ‘real world’ environments in which microbes are hypothesized to grow as bioﬁlms, such as from the lungs of chronically infected Cystic Fibrosis patients in the case of Pseudomonas aeruginosa (Drenkard and Ausubel, 2002; Häussler et al., 2003) and from the plant rhizo- Biofilm inhibitor taurolithocholic acid alters colony morphology, specialized metabolism, and virulence of Pseudomonas aeruginosa Alanna R.

Condren , 1 Lisa Juliane Kahl , 2 Gabriela Boelter , 3 George Kritikos , 3 Manuel Banzhaf , 3 Lars E. P. Dietrich , 2 and Laura M. Sanchez 1 Summary Pseudomonas aeruginosa is an opportunistic human pathogen whose survival is aided by forming communities known as biofilms, in which cells are encased in a self‐produced matrix. We devised a mutant screen based on colony morphology to identify additional genes with previously unappreciated roles in biofilm formation.

ABSTRACT In this study, we report the isolation of small, rough, strongly cohesive colony morphology variants from aging Pseudomonas aeruginosa PAO1 biofilms. Similar to many of the P. aeruginosa colony morphology variants previously described in the literature, these variants autoaggregate in liquid culture and hyperadhere to solid surfaces.

Pseudomonas aeruginosa colony morphology

Pseudomonas aeruginosa is a Gram-negative, rod-shaped, motile organism (polar flagella) which characteristically produce water-soluble pigments which diffuse through the medium. The best known are pyocyanin (blue-green), pyoverdine (yellow-green, fluorescent), and pyorubin (red-brown, produced by a small proportion of strains).

Quorum sensing modulates colony morphology through alkyl quinolones in Pseudomonas aeruginosa. Gupta Rashmi, Schuster Martin; P. aeruginosa isolates demonstrate three types of colonies. Natural isolates from soil or water typically are a small, rough colony, while clinical isolates are likely The distinct green color of P. aeruginosa colonies (Figure 181-2) usually results from a combination of pyoverdin and pyocyanin.

ABSTRACT In this study, we report the isolation of small, rough, strongly cohesive colony morphology variants from aging Pseudomonas aeruginosa PAO1 biofilms. Similar to many of the P. aeruginosa colony morphology variants previously described in the literature, these variants autoaggregate in liquid culture and hyperadhere to solid surfaces.
