What characteristic of drainage is associated with Pseudomonas aeruginosa infection?

Infections caused by Pseudomonas aeruginosa are commonly associated with a distinct green color in drainage. This characteristic is attributed to the production of pyocyanin, a blue-green pigment produced by the bacteria, which can lead to the characteristic coloration of the exudate. The presence of this greenish hue serves as an important clinical indicator of potential infection, particularly in chronic wounds, burns, and other tissue injuries. Recognizing this feature can aid healthcare professionals in making accurate diagnoses and initiating appropriate treatment for infections caused by this opportunistic pathogen.
