Interaction Information:

Comment The authors analysed the sputum of CF (cystic fibrosis) patients by RT-qPCR. Although pyoverdine is known to be an important factor in the survival of P. aeruginosa in CF, the expression levels of the pvd genes (pvdS, pvdH and pvdL), involved in the biosynthesis of pyoverdine, were very low in some samples, consistent with the absence of detectable pyoverdine in some sputum samples. These results suggest that pyoverdine is not absolutely required during chronic infection of the CF airwa.
