Oral Bacteria Found in Alzheimer’s Tissue

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.
Lipopolysaccharide, a component of Porphyromonas gingivalis, was found in four out of 10 Alzheimer’s disease brain samples. It was not found in any samples from the brains of people who did not have Alzheimer’s disease.
