Randy where will those resistant bacteria live? Circulating within the bees
guts or they may sit in the hive as an infective load?
Having been excreted by the larvae, they may be plastered against the cell
wall behind the cocoon or possibly be picked up by the cell cleaners with
their tongues before they begin to feed the babies.
Chance mutations, such as might confer resistance, may occur at random.
They will be rare, but we are dealing with huge numbers. Generally such
departures from the norm come at a cost to the organism and rarely succeed,
being out competed by the conformists but in the special circumstances of the
conformists being destroyed by, in this case, antibiotics, those with the
resistance mutation will have a chance to succeed, multiply and pass on their
strange genes until they, in turn, become the norm.
So the use of antibiotics doesn't create resistance but encourages
resistance to multiply.
