Bacteria grow in thick films, with different types of microbes clustered in patches around individual cells on the tongue’s surface, researchers report online March 24 in Cell Reports.

Bacteria are among the smallest living things. A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria.

We now know that resident bacteria in the gut outnumber the cells of the host by two orders of magnitude. Although labeled “commensal,” these bacteria (and other microorganisms) do more than ...

Another one, called condensin, generally protects the DNA during cell division, and the researchers discovered a defense system that uses components of the condensin mechanism to protect bacteria ...

To determine how bacteria species affect each other’s growth, the researchers cultured pairs of species, one fluorescently labeled and the other unlabeled. They used fluorescence measurements to ...
