Trimethylamine (TMA) and its N-oxide (TMAO) are normal components of human urine. They are present in the diet and also derived from the enterobacterial metabolism of precursors such as choline. Dietary TMA is almost entirely metabolized to and excreted as

Bacterial vaginosis is characterized microbiologically by replacement of the Lactobacillus-predominant vaginal flora by Gardnerella vaginalis, Bacteroides species, Mobiluncus species, and genital mycoplasmas. A standardized, laboratory-based diagnostic test for bacterial vaginosis is desirable in those instances in which a microscope is

Rodents use olfactory cues for species-specific behaviors. For example, mice emit odors to attract mates of the same species, but not competitors of closely related species. This implies rapid evolution of olfactory signaling, although odors and chemosensory receptors involved are

Choline and trimethylamine (TMA) are small molecules that play central roles in biological processes throughout all kingdoms of life. These ubiquitous metabolites are linked through a single biochemical transformation, the conversion of choline to TMA by anaerobic microorganisms. This metabolic

The similarity between sickness behavior syndrome (SBS) in infection and autoimmune disorders and certain symptoms in major depressive disorder (MDD), and the high co-morbidity of autoimmune disorders and MDD, constitutes some of the major evidence for the immune-inflammation hypothesis of
