I found FB on my Harrow Delight for the first time this year. So far that is the only pear I have seen it on, but have to check the orchard closely this weekend. In another thread, you mentioned you break the infected branches out, rather than risk getting the bacteria on your pruners or saw.
Is that still your preferred method? You leave the rough area where you snapped the branch off until you are sure there is no further infection, then go back and prune back cleanly to a bud?
