    Thanks,
    I actually did send an email to our Bee Health Inspector when I got back to the house.
    I was out today feeding all the packages and it is cold out, so I won't have photos until it gets warmer.

    Good move.

    Right now, this is the most important thing you can do. Get them looked at by someone local asap. Your bees and the bees of others around you can be saved by getting clear answers and taking the right action as soon as possible.

    Ben, while you are waiting for the inspector, you might appreciate this video on foul brood.

    I try to learn from my mistakes, and from yours when you give me a heads up :)

    I do believe I have figured out what the heck is wrong , it is Sacbrood. Here is some pictures we just took about 30 minutes ago.
    Let me know if my diagnosis is right. Also the dead pupae does NOT rope out, so that should eliminate AFB right ?

    Also here is the ropey test, I know the Video is not high quality, we are using a regular camera and the large zoom is noisey. When I can afford it I am getting a good digital video camera: )

    Hi all,
    I see alot of mention of visual descriptors for brood diseases and suggestions to treat for AFB but what about tests to rule out AFB? I did not see mention of testing for roping. Looking for scale is another clue though scale is also present in idiopathic brood death syndrome and absent in early cases of AFB. I like to do the Holst Milk Test and described by Randy Oliver. http://scientificbeekeeping.com/sick...st-milk-test-b
    "It is easy to make up a field AFB test kit consisting of a pair of tweezers, a vial of milk powder, and some clear glass vials for running the tests. At home, you can use liquid milk (skim preferred) diluted 1:4, again at the ratio of 1 scale per ½ tsp of diluted milk. When first trying this test, I suggest that you run an uninoculated vial of milk solution side by side for comparison."
    Between testing larval goo for roping and scales for milk protein agglutination, the question of AFB should be ruled out. For those treating an active case of AFB, check with local beekeepers for the local prevalence of terramycin resistance. Tylan is probably a more certain treatment. Also, Ben, what are your mite counts?

    If you watch the video , I did the rope test and all the happened was the pupae exploded in a watery sac , no rope at all . The pictures also show the water sac around the dead pupae.
    I have low levels of mites , and I am currently treating with Formic .

    Sacbrood, no doubt.

    borada,
    Over a span of 20 years of looking into beehives in NY State, visual field diagnosis of AFB is highly accurate. Better than 95% accurate. I don't recall ever getting a Negative reply from the Beltville Bee Lab. So, whereas the Holts Milk Test is definitive, visual observation and ropiness are first and foremost and highly accurate.

    I don't know why the Holts Milk Test wasn't part of our standard procedures other than the time and mess and extra equipment to lug around in our private vehicles. I've seen the test done, but never done one myself. It wasn't part of our training.

    Since Sacbrood is not treatable with antibiotics etc, from what I have read Sacbrood will most likely clear up once the hive is booming again towards summer. Requeening is a last resort for me, I don't have any Queens right now , I already bought Kona queens and made very strong splits with them in order to build up faster for a honey harvest from them.

    So either my queen is not as hygenic as I thought or it is something that bees can just get ? I know it is a virus , but all my reading points to a minor problem , unless it is like 20 % brood coverage , then I will have severe problems .

    So what course of action would you all sugest ?

    Thanks again

    I never used to see sacbrood very often. It was only in someone else's hives, and only one here and there. In recent years I've see a lot of it. I assume it's the Varroa spreading it and maybe genetics contributing.

    Bee health inspector verified my findings , so I guess now I wait and see if it gets better ? I have no course of action.

    What have any of you done to help hives that have Sacbrood ?

    Just requeen?

    I've only had it once and I had it pretty bad.... through a lot of hives... I had it diagnosed by our State Inspector, so I am sure. All I did was wait for the honey flow... and it went away. Mites carry all kinds of viruses, so that is a pretty good guess as to the source. I have tightened up my miticide routine since then and have seen no SB since...
