I have heard of chalkbrood supposedly stopping
>AFB which in my experience is not right.  I have seen plenty of case with
>both AFB and chalkbrood in the same hive.  Where does this claim about
>stopping EFB come from?  

I read in an article in one of the bee mags about 10 or more years ago 
that stated chalk brood has some fatty acid known as linoleic acid, which 
has antimicrobial activity against bacterial honeybee pathogens.    
Linoleic acid is found in in vegtable oils, and in higher amounts in 
peanut oil.  You can perhaps google linoleic acid and foulbrood and get 
some info.

PS. I still have enough oils and greases stocked up from when I used 
treatments to open my very own Jiffy Lube.  

Best Wishes,
