It does not look like european foul brood, I've got some of that in my apiary. It does look like sacbrood. Send off a sample to be sure.

So what are the consequences and procedures with sacbrood?


----------



## George Fergusson (May 19, 2005)

Here's a pretty good page on sacbrood.

http://www2.dpi.qld.gov.au/bees/4925.html

It's a virus so there's no sense in an antibiotic treatment. There are some environmental considerations (and possible causes) and requeening is often a consideration but not a necessity. Basically it's a matter of removing the affected combs. After several months the infected brood is no longer hazardous but when it's fresh, it's pretty virulent. Old combs can be stored if they're not too infected or melted down if they're really loaded.

Thanks George....... another one for the bookmarks.

Looks like sac brood to me too. I saw some the other day in someones hive. The hive was doing really well and there were only a few here and there.

It usually happens in the spring and clears up by itself.

From my website:

"Sacbrood. Caused by a virus usually called SBV (SacBrood Virus). Symptoms are the spotty brood patterns as other brood diseases but the larvae are in a sack with their heads raised. As in any brood disease, breaking the brood cycle may help. It usually goes away in late spring. Requeening sometimes helps also.

"Breaking the Brood cycle. For all of the brood diseases this is helpful. To do this you simply have to put the hive in a position that there is no longer any brood. Especially no open brood. If you are planning to requeen anyway, just kill the old queen and wait a week and then destroy any queen cells. Don't go three or they will have raised a new queen. Wait another two weeks and then introduce a new queen (order the appropriate amount ahead of time). If you want to raise your own, just remove the old queen (put her in a cage or put her in a nuc somewhere in case they fail to raise a new one) and let them raise a queen. By the time the new queen is laying there will be no more brood. A hairclip catcher works for a cage. The attendant bees can get in and out and the queen cannot. " --Michael Bush

Thank you all for your response. It seems pretty unanimous that it appears to be sacbrood.

dcross - Thanks for the link to a free service for analyzing infected brood and bees. This is good to know.

George - That is a great webpage on sacbrood. Since there was only one frame of comb showing signs of sacbrood, and only a small amount at that, I think I will just keep an eye on it and take action if it persist or gets worse. Last week, this brood box had 7 to 8 frames full of capped brood and I discovered the sacbrood yesterday when I was manipulating frames to help prevent swarming using the "Snelgrove Technique". 
I did this about 6 weeks ago to one of my strongest hives at that time and that hive has drawn comb and capped two medium supers full of honey since then and we really don't have a flow going yet, and I got another hive started to boot. 
June and July starts our Black Mangrove bloom and we have hundreds of acres of mangrove right across the waterway from us.

Michael - Thanks for the confirmation. I respect you for your knowledge and willingness to help all us new beeks. I've spent many hours on your website in the past and forgot that you had a section on bee pests.

Here is an extreme rarity on these lists today, 
an honest beekeeper!









George, If you are to survive on these lists, you will have to learn to describe disease as something youve seen before in 
other peoples colonies'.  

You can borrow my car anytime!









Best Wishes,

Aw Shucks. I lost all my blushes a long time ago Joe!

I had my apiary inspected by Tony Jadczak this spring. He found european foulbrood in 4 colonies. I saw it, poked at it, smelled it. Smells like rotten fish.

I'll have to remember that.







But in this case I have a lot of witnesses.







It was at the bee club meeting last month and we all went through a hive together. I'd really never seen anything but pictures of it before that, but it was the classic picture of sac brood.

--I'd really never seen anything but pictures of it before that, but it was the classic picture of sac brood.

Need also to look for dull grey larve in the early stages turning yellow (the highly infectious stage) then yellow with a dark head, brown then black. Capped brood will sometimes have a pin hole in them with a dead larvea inside.

Looks to be but a very minor case, but it might be symptomatic of bees that are not very hygenic, I myself would requeen a colony if found to have sac brood, and not wait for it to clear. I would want to eliminate the genetics by requeening with another colony that does not have sacbrood symptoms.

## naturebee (Dec 25, 2004)

One more thing,









Seems odd that sac brood would occur in such a strong hive as the poster describes, although Im sure it does happen. It is known that stress factors seem to influence the development of brood diseases like sac brood and chalk brood.

Just wondering if the poster has provided proper ventilation. I would imagine that for Florida at this time of year the entrance should be wide open and roof tilted to provide adequate air circulation. If not, I would certinally consider providing ventilation.

An update to the sacbroud problem. I forgot to mention that I had removed the frame that had the sacbroud problem. Last Sunday, I did another inspection of the hive and found no signs of sacbroud.







The ant's have clean up this frame, removing all the eggs and larva. Will it be OK to put this frame back in the hive? I will continue to monitor this hive closely. Again, thanks to all for your support.

>Just wondering if the poster has provided proper ventilation. Joe, I have SBBs on all my hives. I use migratory covers with "popcicle sticks" to leave a slight space between the cover and box.

It's exactly the senario I saw. It was a strong hive, wall to wall bees, lots of capped brood. A good laying pattern except a few pierced cappings with sacbrood inside.

Did anyone notice the Varroa mite on the bee in the bottom right of this shot?

Yes Mike, sacbrood can occure in strong colonies.

Might me sugestive of non hygenic bees.
