Trimethylamine, a marker for BV

Posted by urbfo on 22 Feb 2013 at 10:29 GMT

I have with interest read your paper.
I noted the wide range of metabolites you found. I wonder if you were able to analyze for trimethylamine (TMA) and/or trimethylamine oxide (TMAO)? TMA is the best characterized metabolite that accounts for the bad odor of spoiling fish (1). We and others have previously concluded that TMA is essential in elicitation of the bad smell of BV (2,3,4). Addition of analysis for TMA/TMAO in a multi-omics systems-based evaluation of bacterial vaginosis could thus led to insights into the understanding of the pathophysiology of bacterial vaginosis as well as be of diagnostic value.
