Why does my catheter bag turn blue?

Why does my catheter bag turn blue?

The purple discoloration of the catheter bags is due to the presence of the purple pigment indigo and the blue pigment indirubin [1, 5]. The proposed mechanism for pigment production is through altered metabolism of tryptophan [6].

What bacteria causes blue urine?

This converts indoxyl sulfate in the urine into the red and blue colored compounds indirubin and indigo. The most commonly implicated bacteria are Providencia stuartii, Providencia rettgeri, Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli, Morganella morganii, and Pseudomonas aeruginosa.

The pathogenesis of PUBS is related to the combination of these two pigments produced from the metabolism of tryptophan.
