Hi Peter

I am wondering why there is a need to 'presume' anything.

One difficulty that we have here is the idea of something being 'similar' or 
'very different'; surely these terms are subjective?  My view, from what I 
have read so far, is that although there are obvious similarities, there are 
also very significant differences between the two, particularly with regards 
to their virulence and the damage done to the gut, the seasonal differences 
in outbreaks, and the 'defaecation effect'.
Best wishes
