Abstract

ABSTRACT A recent North American study detected Chlamydia pneumoniae in 17 of 19 brains of Alzheimer's patients and supposed a C. pneumoniae infection to be a risk factor for Alzheimer's disease (AD). In this study, we analyzed paraffin-embedded tissue samples of 20 AD patients by nested PCR and immunocytochemistry with a panel of antichlamydial antibodies and could detect neither C. pneumoniae -specific DNA nor chlamydial antigens. From our data, the presence of C. pneumoniae in the brains of Alzheimer's patients is not a common phenomenon; an association remains questionable.
