Pretty difficult to make a diagnosis on a photograph but a few closeups would make me recommend you call your bee inspector - just to be on the safe side.You’re a new beekeeper? . I’d definitely get that checked by your bee inspector, you’ve got some depressed cappings and slumped larvae. I’d go a bad case of sac brood but I’d get the efb test kit out if I saw that to be on the safe side!
Treatment is for 4 biscuits, not 2, so knockdown likely to have been partial and varroa may be high, but the distorted advanced open brood looks suspicious. Definitely follow the advice given to call your SBI.Apivar Life (Thymol) in September (the recommended 2 treatments
What ever it is it’s quite advanced if it was afb there be some gooey cells visible I suspect.When I last treated with ApiLife Var it didn't knock down the varroa enough. I'm not a fan.
Noone has mentioned AFB yet. Sunken cappings but they don't look greasy. I'd have a broggle in a few of these. Probably with your local bee inspector.
Can't see any EFB type, twisted and melted larvae. Or any sacbrood pointed 'slipper' like larvae.
I wonder (with your experience) , if it's EFB, would you consider a change of queen for a genetic refresh but at the same time do a shook swarm perhaps?Irrespective of the outcome I would cull anyway.....this is a defective situation that is not going to go away without a genetic refresh
