Hi all,

I am wondering if you can comment on statistical interpretation of dysbiotic microbiome. For example, we treated a system with antimicrobials and now community is changed. Initial community is inhibited and new community took over the system. Now the question is, how can we say that this change is dysbiosis? Is there any statistical criteria established? Or its just qualitative interpretation? I assume that diversity and richness analysis may be used for this purpose but again what would be cutoff for such a purpose?

Thanks and looking forward to to your opinions...

Best,

Arslan
