Pathobiome Paradigm
Some future research will focus on a spectrum of pathogens instead of a "one pathogen-one disease" vision.

Lyme Disease vs Chronic Fatigue Syndrome
Lyme Disease and Chronic Fatigue Syndrome are different diseases. Research is published on Cerebrospinal Fluid and distinct differences were found.
