Oral bacteria can lead to life-threatening brain abscesses

Bacteria known to cause oral infections may contribute to the development of life-threatening brain abscesses, according to a study.

If the connection between oral health and general health is already known, a new study has focused on brain abscesses. As reported by News Medical, researchers have focused on the connection between the occurrence of brain abscesses and the presence of certain bacteria in the mouth.

According to this study, bacteria known to cause oral infections may be a source of infection leading to life-threatening brain abscesses. These results were published in Journal for Dentistry.

A high presence of bacteria

As part of this study, the researchers reviewed the records of 87 patients admitted to the hospital with brain abscesses. To determine the cause of these abscesses, they used microbiological data obtained from abscess samples. Results? The 52 patients for whom no cause had been identified were three times more likely to have oral bacteria in their samples.

In addition, these patients had a significantly higher number of Streptococcus anginosus, a bacterium that can be responsible for the occurrence of pharyngitis, bacteremia and infections in organs such as the brain, lungs and liver, point out the authors of this study. This bacteria is often found in dental abscesses.

Watch your mouth

“While many potential causes of brain abscesses are recognized, the origin of the infection often remains clinically unidentified. However, it was still surprisingly common to find oral bacteria in brain abscesses of unexplained origin.” details dr. Holly Roy, NIHR Clinical Associate Professor of Neurosurgery and lead author. Before adding:It also highlights the importance of improving dental care and oral hygiene more generally.”

So, in order to maintain brain health, this study proves once again the importance of taking care of the hygiene of your mouth. Other clinical trials are underway to investigate the link between gum health and Alzheimer’s disease.
