Gum disease and heart disease linked through common bacteria

Gum disease and heart disease linked through common bacteriaA common bacterium has been found in both gum disease and heart disease which means a person’s heart can become affected if they have periodontal disease. A research team from Örebro University in Sweden uncovered the bacteria – Porphyromonas gingivalis (or P. gingivalis) – which is found in both periodontal disease and heart disease.

When arteries become clogged with fat and cholesterol, it can result in atherosclerosis, or hardening of the arteries; this can prompt a blood clot and lead to a heart attack. Researchers found P. gingivalis to be present in the plaque of arteries.


To reach their findings researchers cultured human aortic smooth muscle cells and infected them with P. gingivalis. When muscle cells were injected they secreted enzymes called gingipains which change the ratio between two proteins involved in inflammation which resulted in the boost of inflammation. This inflammation is believed to play an important role in atherosclerosis.

Researchers are hopeful that the new findings will help find a way to treat both gum disease and heart disease. The findings were published in the journal Infection and Immunity.
