Black and McKay noted that mottled teeth did not seem to have a higher incidence of tooth decay, and Dean extended those findings, although that was not his job. A man was specifically assigned to investigate the damage that a particular chemical did to teeth, but somehow concluded that the chemical was instead good for teeth. Ironically, the PHS spent the ten years after trying to eliminate fluorine ions from the water supply, given the tooth mottling findings.

Before the diagnosis was made, patients would dismiss those symptoms with the statement: That resigned characterization implies that the longevity of the symptoms rules out a reversible cause.

Subsequent resolution of the long standing symptoms on antibiotic therapy for LD belies that notion. Symptoms of LD can begin within days of inoculation with Bb or appear belatedly, but usually in the first to fourth month.

Mice innoculated intraperitoneally had Bb demonstrated in the brain on biopsy 12 hours later with a peak at 48 hours Stockholm Conference, If dissemination can occur early, then staging the disease according to the temporal appearance of symptoms may be irrelevant.
