How long, how many treatments, should treatments be administered in the 
propolactic treatment of the yard?

Juanse, the key word here is "live."  The bacteria can only grow and
reproduce within either the bee gut or the body cavity.  The spores,
although technically "alive" do not grow, reproduce, or adapt.  In a bee
population, under constant antibiotic exposure, only those few bacteria
possessing resistant traits can grow and reproduce, and they may do so
especially well, since the competition may have been killed by the
antibiotic.

>When AFB is detected in a bee yard ( 2 hive or 2000  hive commercial

yard) the entire yard is treated for AFB (as opposed to only treating the
hives showing AFB signs).

I agree with Bob here--this is exactly what I'm doing today in the yard in
which I found the AFB deadout.  The suggestion by another to simply remove
single diseased combs is a recipe, IMHO, for disaster.
