Black spots in beehive, brood and bee larvae. EFB – European Foul Brood?

http://www.mahakobees.com/blog

Black spots in your beehive, brood frames and bee larvae? EFB – European Foul Brood questions.

What do you think it is? EFB (European Foul Brood) perhaps? We are perplexed somewhat, as these black spots are distributed throughout the frame on all larvae, but the pollen cells are clean. The consistency and distribution of the black smears or spots is very even, that we think it is not bee smoker and ashes related. In which case, what is this? Fellow Beekeepers we seek your comments and expert diagnosis.

We have researched the issue and cannot find anything conclusive. Please take a look at the video and let us know in the comments section or via email if you have experience with this, seen it in the past or perhaps are aware of the issue and perhaps how to treat this. European Foul Brood (EFB) is a suspect, but it does not meet all the criteria. American Foul Brood (AFB) is also not the issue here. Mold? Or other diseases we may not have come across? 

The beehive that this frame was extracted from was perfectly OK. The video is taken 1 day from its extraction from the hive, so you can see ants crawling around, but they would not be the cause of these black markings. Could it bee fungus? Hopefully nothing more serious like AFB or EFB, even though these symptoms are not indicative of those. No other similar symptoms exist in the beehive itself and the queen is laying fine. The colony is very strong, possibly too strong and is getting ready to swarm as we approach spring and warmer temperatures. If there is a treatment we should investigate, please let us know.

We appreciate all beekeepers opinions, feedback and advice. Especially from the experienced and expert beekeepers. Your time and input is much appreciated. Hopefully its something minor and not EFB / AFB related.
