Do Pseudomonas spp. impact orchids negatively?

[sapphirerose]

Do Pseudomonas spp. hurt orchids? I have noticed a tendency of my tap-watered orchids to develop rots no matter how carefully I water. My rain-watered orchids do not. Our water quality is decent, but I know my city has been fighting Pseudomonas biofilms in the pipes. I do not know which Pseudomonas species are present. That has never been made clear.

My husband's work and the local Children's hospital both had to deal with the issues it was causing. It is really only a problem for immune compromised humans and animals, but what about orchids?

Would an RO system remove Pseudomonas?
