A reader asked, Which genus should I give highest priority in general?

This is an easy answer using the Conditions populated from studies on the US National Library of Medicine on 127 different conditions. The results are below for those that are seen in at least 10% of conditions.

Below that is a table showing the direction of shifts.

Direction Of Shifts for each bacteria

For some it is balanced, for others only one direction is significant.

• “H” means that this genus for medical conditions are abnormally high for people with a condition
• “L” means that this genus for medical conditions are abnormally low for people with a condition
• NOTE: For some conditions, both High and Low are reported, i.e. the population of this genus becomes abnormal. For details see: https://microbiomeprescription.com/Library/PubMed
