Abstract

We identified the novel presence of nonanoic acid for the first time as a M. tb-linked marker in the CSF of cases of TBM, possibly as a degradation product of the M. tb cell wall. Propanoic acid can be related to perturbed brain neuro-energetics and neuro-inflammation in TBM cases and is likely a host-response metabolite. Mannose and arabinose-supposed surrogates for lipoarabinomannan, a component of the M. tb cell wall-were not reliable markers for M. tb. Further research should focus on the analysis of fatty acids in the CSF of patients with TBM.
