My opinion: we're not dealing with Ebola here. It's too much trouble for me to disinfect after every cut. The trees will probably all get exposed to the same thing anyway due to insects, etc. Now if I had a tree or plant that I new had some bad disease, I would do it.
Not saying you shouldn't, just saying, even if you don't, probably nothing bad will happen. Plus, I doubt a quick wipe would truly disinfect pruners. Probably would need to dunk them in a disinfectant bath for some length of time to really accomplish the task. They have grooves/surface imperfections that will continue to harbor microorganisms, etc. And I'm definitely not doing that.
