PURPOSE
To study surgically excised vascular tissue from lower extremities for the presence of Chlamydia pneumoniae, to extend the previously described association of the organism with atherosclerosis.
METHODS
Arterial biopsy specimens obtained from femoral and popliteal arteries during bypass operation for claudication were examined by immunocytochemical analysis and polymerase chain reaction for the presence of organisms.
RESULTS
C. pneumoniae was detected in atherosclerotic plaques by either method in either artery of 11 of 23 patients (48%). Eight of 21 popliteal and three of 18 femoral arteries had positive results.
CONCLUSIONS
Detection of C. pneumoniae in peripheral arteries indicates that the organism is widespread in atherosclerosis of the vascular system.
