Actually, those symptoms can be associated with other problems. For
example, you can get a "foul" smell with some ripening honeys and
sacbrood will give some liquid with brown larva. We are asking a new
beekeeper to distinguish differences between what many have never seen
or smelled.

The better indicators for the new beekeeper are: the pupal tongue
sticking straight up from the remains on the cell floor; the larval
remains "rope out" when a matchstick or toothpick are inserted in the
larval remains and pulled out (does not always work with every cell);
cappings are shrunken and small holes appear in them; and scale on the
bottom of cells that does not come out. (All that in addition to the
differences between AFB and EFB and the color of dieing/dead pupa,
again, things an expert needs to evaluate.) BTW, all this is in just
about every comprehensive Beekeeping book.
