I have a hive that came through winter weak and I noticed several cells with dead larva and pupa. It seems like the larva are being affected once they are capped. There is no smell. The cappings are not sunken. The affected cells are very spotty here and there. They dead larva are watery, not stringy or ropy when.

Is there any good way to tell the difference between sacbrood and foulbrood

I had the same issue coming out of winter. About the only definite test is to send comb off to Beltsville MD. I looked at all the pictures on the net I could find and it looked like Sacbrood to me however many told me it was European Foul Brood. I requeened with a VSH and they are just now starting to turn the corner but still have a little bit of the disease. Both are stress related diseases. Don't know if this helps, but yours sounds identical to mine.
