Nasty Nosema quandary

[EK.Bee]

Thanks
I guess you would need to have previously carried out a Bailley comb changed then
=to have the drawn comb to put above them to transfer onto?
3 frames would be too weak to bailley onto foundation (according to Graeme Sharpe's recent lecture at ABKA)
Assuming its Nosema Apis anyway

My reading is:-

It does not say (does not matter) which type of nosema. (If you have further info on different treatment for different types I am interested to know.)
To manage to ensure its survival it needs a "nosema " bailey comb change (no mention of a past one, you are dealing with the current situation).
A "nosema" BC change one is as described in the article, a "full" or "normal" one would be too much for this.
It does not say what time of year, are there any differences (say) between spring and autumn treatment? Perhaps someone else can come in on this part.
Also mention re-queening susceptible colonies.
Also, apiary hygiene is important to stop the spread. Usual - washing tools, bee suit, etc.. Also scorch boxes, floors, and change comb every 3 years. All assist in "ensuring survival"

Agree with DR, thymolated syrup would help.

In my diseases exam I suggested a polynuc initially and thymol syrup (and even stated where the examiner could read the trial on thymolated syrup). Wrong.

The answer examiners are looking for is a Bailey comb exchange. Dummy down if the colony is not large.
