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.

Mythbuster: Ideas that bacterial collaborations within microbiomes are generous and exclusive appear to be quite wrong.

Study Shows How Bacteria Behave Differently in Humans Compared to the Lab

Image shows a rendered confocal laser scanning micrograph of a mixed species bacterial biofilm observed in a chronic wound model of infection. Staphylococcus aureus (yellow) and Pseudomonas aeruginosa (purple), organize themselves in small, dense clusters of cells called aggregates.
