Artificial sweetener usage thought to facilitate C difficile virulence

Actual page title: &quot;Dietary trehalose enhances virulence of epidemic Clostridium difficile&quot;<p>Submitting with a genericized title causes confusion with common consumer ASes like aspartame, sucralose, Ace-K, etc.<p>Submitted earlier with original title:<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16778032" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16778032</a>

I think I read about this on HN before. This is a common sugar like additive put in icecream because of it&#x27;s texture properties. Its like the favorite food of the bug mentioned here. How did an artifical ingredient become a prefered food for it?
