There are likely other pathogens involved.  Disinfection, or even just a
rest, may cause them to become inactive.  Disinfection shouldn't hurt, and
if you have irradiation available, would probably help to give the bees
pathogen-free combs (the Aussies do this).

My current article in ABJ addresses this--I'd have a hard time recommending
major comb replacement unless you've use a lot of miticides or have been
exposed to major pesticides or fungicides.  Minor comb replacement each year
may be a good practice, but as you say, you lose honey with each comb that
they have to draw.

This does not apply to N apis, which definitely contaminates the combs.
