"...patients with reduced immune function...shared an eczema-like skin condition...had types of bacteria and fungi on their skin not found on healthy individuals...an imbalance in microbial diversity at a given site may contribute to disease...correcting the diversity of microbes on the skin, not just targeting pathogenic ones, may aid in the treatment of disease."

Given what we've seen in treating fungal candida from past Antibiotic
use, this makes perfect sense. Antibiotics
alter immune function and microbial diversity.
