Appreciate your reply!

Any bacteria (good or bad) can be expected to spread to a degree from one place to another in an environment. What I mean by colonization is simply that bacteria from the rotted tissue could have gotten in the medium (bark, LECA, whatever) that you are growing plants in.
Think of it this way: if you have a family member that gets a staph or strep infection, you would want to make sure that you disinfect surfaces (counters, door knobs, etc.) that are shared by the rest of the family. You can disinfect pots and tools with things like Physan, peroxide, etc., but it is probably not the best idea (or economical) to drench medium with a disinfectant. More practical to un-pot, clean the plant (possibly wipe the leaves with a paper towel and peroxide), and re-pot in a clean pot with clean medium.
The dyna-gro should be fine if not over-applied. I find Ca applied as gypsum (or Plaster of Paris) adequate.
