Despite published evidence that IQS (2-(2-hydroxylphenyl)-thiazole-4-carbaldehyde) is in fact aeruginaldehyde, a by-product of the siderophore pyochelin biosynthesis or degradation and that the ambABCDE genes are not responsible for IQS synthesis, several authors, including in top review journals, perpetuate the wrong information. I hope that this short comment will clarify the situation once and for all.
Keywords: Pseudomonas aeruginosa; IQS; aeruginaldehyde; pyochelin; quorum sensing.
