Abstract

Chlamydia pneumoniae is a common respiratory pathogen. Recent studies have demonstrated the presence of C. pneumoniae in coronary and aortic atherosclerotic lesions. To study the role of C. pneumoniae in atherosclerosis, we investigated the susceptibilities of three different cells of the human vascular wall to infection with C. pneumoniae AR-39. These cell types were endothelial cells, smooth muscle cells, and macrophages derived from peripheral blood monocytes. Infection was assessed by using a direct fluorescent antibody to assess inclusion counts. Duplicate cell samples were harvested 3 days postinfection and were passed in HL cells, a susceptible human epithelial cell line, to determine if infectious organisms were produced. Endothelial cells, smooth muscle cells, and macrophages were capable of supporting C. pneumoniae growth in vitro. These results showed that three different cell types known to be important in atherogenesis are susceptible to infection with C. pneumoniae.
