The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.
Research on humans and dogs reveals that the communities of microorganisms found on the skin, on the tongue and in the intestine are affected differently by age and cohabitation.

High-throughput sequencing has been used to analyze the microbiome of mouse corpses over a period of 48 days, and to provide an accurate estimate of the time since death.
The sequencing of microbial genomes reveals that the presence of a particular microbial species in the gut may increase the risk of the autoimmune disease rheumatoid arthritis.
