Bacteria known to cause oral infections may also be a contributory factor in patients developing potentially life-threatening abscesses on the brain, new research has shown. The study, published in the Journal of Dentistry, investigated brain abscesses and their association with bacteria that occur in the oral cavity. While this type of abscess is relatively uncommon, it can result in significant mortality and morbidity.

Researchers examined the records of 87 patients admitted to hospital with brain abscesses, and used microbiological data obtained from abscess sampling and peripheral cultures.

This allowed them to investigate the presence of oral bacteria in patients’ brain abscesses where a cause of the abscess had either been found, as was the case in just 35 patients, or not...

In a study of more than 1,200 women in the U.S., average age 63 years, 10 kinds of oral bacteria were associated with a higher risk of developing high blood pressure, while five strains of bacteria were linked with lower hypertension risk. The observational study cannot prove cause and effect; however, the findings highlight possible opportunities to enhance hypertension prevention through targeted oral care, researchers said.

Some oral bacteria were associated with the development of hypertension, also known as high blood pressure, in postmenopausal women, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American H...

An international team has found evidence that suggests certain types of oral bacteria may cause or exacerbate bowel disorders. In their paper published in the journal Science, the group describes testing the impact of introducing bacteria found in the mouths of humans to mice models. Xuetao Cao with the Chinese Academy of Medical Sciences offers a Perspective piece on the work done by the team in the same journal issue and suggests that the work might one day lead to the development of new kinds of treatments for common bowel disorders.
