> I have heard it said more than once, by a prominent, now retired bee scientist, that chalkbrook and AFB will not be present in the same hive at the same time; that chalkbrood surpresses AFB. I always wondered about this, thinking that if chalkbrood supresses AFB then there might be some sort of silver bullet in the former for the later. I have seen the same comments printed and when I raised this issue with our bee inspectors, they have been told me that they have seen both AFB and CB in the same hive. When I first read this I thought we might have found the silver bullet but, unfortunately, I think not.
