Test developed to identify type of MS
The test relies on detecting compounds in a pathway of the brain using a substance called tryptophan.
"By increasing our understanding of how our cells process tryptophan, we will be better able to identify its involvement in many neuro-degenerative diseases," : http://www.abc.net.au/news/2017-02-04/new-ms-blood-test-can-identify-types-of-multiple-sclerosis/8236336
The prescence of c.pneumoniae causes disruption in tryptophan metabolism, and restricting it (by restricting protein intake...particularly proteins rich in tryptophan) is a key component of treating c.pneumoniae: "the body’s primary defense mechanism against C. pneumoniae is tryptophan deprivation. This is why people with chronic brain infections have symptoms of serotonin deprivation, including depression, anxiety, insomnia, fatigue, impaired ability to concentrate, and low self-confidence. It’s important not to relieve this by tryptophan or 5-HTP supplementation, both of which promote bacterial growth." : http://perfecthealthdiet.com/2010/07/eleven-steps-for-overcoming-alzheimer%E2%80%99s-and-other-chronic-infectious-diseases/
From the pen of Prof Stratton "Avoid Red Meats Red meats, including beef and dark turkey as well as tuna and salmon contain tryptophan and should be avoided as much as possible. ": http://cpnhelp.org/secondary_porphyria_what_
