Highly organized structures discovered in microbial communities with MBL imaging approach

Bacteria usually live in mixed communities with many different kinds of bacteria present. But it’s been largely unknown how these communities are organized, because the technology didn’t exist to see how they are structured in space.

Hedgehog Structure in Dental Plaque Microbiome
