It appears that the Nebraska talk is summarized in this on-line  paper:

At the risk of starting a feud, a word of caution, the comments about  
chalkbrood fungus preventing EFB; stonebrood fungus preventing Nosema need to  be 
considered in the context of the cited references.
 
Like others, I've seen chalkbrood and EFB in hives at the same time; so  that 
statement just doesn't hold up to field observations.
 
The paper by Martha Gilliam  that is cited is a good start to  understanding 
the microbiology inside a hive.  I accept Martha as an  expert and her paper 
was peer-reviewed.  She does talk about the complexity  of the microbiological 
community inside a hive.  As such, this is a good  reference to the topic.
 
But the next three references to support these two claims are  Wiki pages and 
on-line sources, where authorship is unknown.
 
However, in this case, the cited Wiki page correctly states that  fumadil is 
derived from an Aspergillus fungus and that this drug is  used to treat 
Nosema.  Its also correct in stating that stonebrood is  associated with several 
species of Aspergillus fungus.
 
But, the Wiki page does not say that Stonebrood prevents Nosema.
 
That's a jump in logic that isn't supported by the statements in the  
'citation', and we don't even know whether the author of the  'cited' Wiki source is 
an authority (although in this case I'd more or  less agree with the Wiki 
statements).   
 
Don't get me wrong, we still don't understand all of the interactions at  the 
microbiology level.  For example, there are studies that show that  the 
bacteria Wolbachia alters the reproductive viability of its hosts, and may  have 
other affects and interactions.
 
My objection is to sweeping generalizations based on 'citations' to unknown  
authors and misquoting of references.
