Periodontitis Bacteria Love Colon and Dirt Microbes

Bacteria behind acute periodontitis. Aggregatibacter actinomycetemcomitans most often lives peacefully in the mouth until circumstances lead it to become infectious. It forms flower-like colonies, here under a microscope sporting a colorful stain added by a researcher. Aa is gram-negative. Credit: Derren Ready (2012) CIL:38942, CIL.
