Oral Bacteria Found in Alzheimer’s Tissue

A particular type of oral bacteria has been linked to Alzheimer’s disease, according to a new study conducted by an international team of researchers.

They believe that the bacterium found in the brain can trigger immune system responses and pathological changes, which could lead to diseases such as Alzheimer’s.

For the study, Lakshmyya Kesavalu, an associate professor in the College of Dentistry at the University of Florida, and a team of international researchers examined the brain tissues of 10 Alzheimer’s patients and compared them with that of 10 non-Alzheimer’s brain samples.

A special type of test called immunofluorescence labeling and immunoblotting was used to screen the brains and find an oral bacterium called lipopolysaccharide.

  1. The oral bacterium is not called lipopolysaccharide. Later in the article, it is explained that the lipopolysaccharide is a component of Porphyromonas gingivalis, an oral bacterium. I just wanted to clarify that point for others that come to read the story.
  2. Samantha you are correct. I think the original author should have referenced a "bacterial lipopolysaccharide" not "an oral bacterium called lipopolysaccharide." The actual bacterium is Porphyromonas gingivalis as you pointed out. Thank you.
