Gut microbes may cause some COVID-19 patients to have higher blood clot risk
A gut microbial metabolite called 2-methylbutyrylcarnitine (2MBC) plays a role in exacerbating thrombosis – the formation of blood clots – and is accumulated in individuals with COVID-19.

Fatty acid produced by gut bacteria directly influences fat metabolism in animals
Researchers investigating gut bacteria that produce fatty acids with a special chemical structure, known as a cyclopropane ring, showed that these can be converted into signals that turn on fat desaturation in the nematode C. elegans.
