While the bacterium is a pathogen that is responsible for various hospital-acquired infections, these infections are particularly severe among individuals with a compromised immune system. Two distinctive colony morphologies were noted in a collection of Pseudomonas aeruginosa transposon insertion mutants. One set of mutants formed wrinkled colonies of autoaggregating cells. Suppressor analysis of a subset of these mutants showed that this was due to the action of the regulator WspR and linked this regulator (and the chemosensory pathway to which it belongs) to genes that encode Pseudomonas aeruginosa colonies on agar P. aeruginosa strains produce two types of soluble pigments, the fluorescent pigment pyoverdin and the blue pigment pyocyanin.

May 23, 2018 In the Cetrimide Agar medium, the selective medium for Pseudomonas aeruginosa, colonies are Medium-sized & irregular growth is observed Download scientific diagram | Colony morphology of Pseudomonas aeruginosa in MacConkey agar showing 2-3 mm, flat, smooth, non-lactose fermenting Pseudomonas aeruginosa is also species, the type species is Pseudomonas aeruginosa. state the morphological characteristics of Pseudomonas;. ○ The bacteria which form mucoid colonies are more virulent compared to others. Pseudomonas aeruginosa is a Gram-negative, rod-shaped, motile organism ( polar flagella) which characteristically produce water-soluble pigments which diffuse Dec 18, 2019 We observed altered morphology of colony biofilms and changes in specialized metabolism when P. aeruginosa PA14 was exposed to TLCA.

Despite P. aeruginosa biomass harvested from a tube biofilm reactor produced two prevalent colony morphologies: the wild-type PAO1 colony morphology (Fig. 1a) and the smaller, wrinkled, “sticky” colony morphology (Fig. 1b).
