G test for significant difference

Question

[rahulgenexpress]

I am studying the gut microbiome of patients and healthy controls, to show significant difference can I use G test?

It seems unlikely that you'd get an explicit count of the members of different phyla in your sample, so I don't think you can use this count-based test.
