A common bacteria usually found in the mouth and gastrointestinal tract, Streptococcus anginosis, may be abundant in the guts of people with stroke and is associated with a worse prognosis and increased risk of death, according to a preliminary study to be presented at the American Stroke Association’s International Stroke Conference 2025. The meeting is in Los Angeles, Feb. 5-7, 2025 and is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.
“In the future, if there was a quick test to detect harmful bacteria in the mouth and gut, we could use the information to help calculate stroke risk. Targeting these specific harmful oral bacteria may help prevent stroke,” said Shuichi Tonomura, M.D., lead author of the study and staff physician in the department of neurology at the National Cerebral and Cardiovascular Center in Osaka, Japan.
