BACKGROUND: Chlamydia pneumoniae and the herpes viruses cytomegalovirus (CMV) and herpes simplex virus type 1 (HSV-1) have been associated with human atherosclerosis in seroepidemiological and separate histopathological studies. We investigated the concurrent presence of these microorganisms in patients undergoing carotid endarterectomy. METHODS AND RESULTS: Endarterectomy specimens from 76 patients with carotid artery stenosis were stained for C. pneumoniae, CMV, and HSV-1 particles with specific IgG monoclonal antibodies by the avidin-biotin-peroxidase method. IgG antibodies to CMV and C. pneumoniae were also measured in the serum. These were correlated with plaque morphology and the presence of the microorganisms in the atherosclerotic plaques. C. pneumoniae was detected in 54 (71%) (95% confidence interval [CI], 59.5% to 80.9%), CMV was detected in 27 (35.5%) (CI, 24.9% to 47.3%), and HSV-1 was detected in 8 (10.5%) (CI, 4.7% to 19.7%) versus none of 20 (0%) control normal carotid artery and aortic tissue (autopsy) specimens (CI, 0% to 16.8%) (P<.001 for CMV and C. pneumoniae). At least one microorganism was detected in 59 of the specimens (77.6%) (CI, 66.6% to 86.4%), with a single microorganism present only in 35 (46%), two microorganisms present in 18 (23.7%) (CI, 14.7% to 34.8%), and all three present in 6 (7.9%) (CI, 3.0% to 16.4%). Atherosclerotic plaques with thrombosis were more likely to have C. pneumoniae (80.4%) or CMV (57.8%) than were plaques without thrombos...
