Those low antibody titres in early testing were “already a red flag”, he says.

Antibody titres are shown in a logarithmic scale, and pale red and blue areas denote 95% confidence intervals.

Titres for which nonlinear regression was predicted to be below this threshold were reported as a titre half the limit of confidence.

The first is a clinically silent exponential phase, the rate of which is not limited by PrPC concentration, that rapidly reaches a maximal prion titre.

The presence of Lactobacillus salivarius in the oral cavity and faeces correlates positively with antibody titres, and this microorganism was more likely to be present in active cases of rheumatoid arthritis than in controls.
