For those of you who may want to work with Horse Chestnut the following information will be of interest to you.
All information kindly supplied by Dr J F Webber, Principal Pathologist, Forest Research.
We have never done any tests to see if the bacterium would remain alive in wood once a piece was polished. I am sure that it would not be active, ie would not continue to grow, as the wood would be at a lower moisture content once sawn and seasoned. But I strongly suspect that it would not survive for very long in the seasoned wood, because Pseudomonas does not produce resistant spores.
As to whether it makes the wood more nasty/toxic, again I would have thought it unlikely as this is strictly a tree pathogen, and although I suppose it could be allergenic, I would have thought the particles of wood would be more problematic than the bacterium.
We don't know how this particular bacterium is dispersed, although in general Pseudomonas species tend to be dispersed in water splash and films of water, and are not thought to survive long under dry conditions.
