Chlamydia pneumoniae is a respiratory pathogen that has been associated with chronic inflammatory diseases such as asthma and atherosclerosis. Recent isolation of C. pneumoniae from human carotid and coronary atheromas provides additional support for a role of this organism in atherogenesis. We characterized the coronary strain C. pneumoniae A-03 by sequence analysis of the major outer membrane protein gene (omp1). In addition, the in vitro activities of A-03 and three respiratory strains of C. pneumoniae (BAL-16, TW-183, and T-2634) were examined in infected human umbilical vein endothelial cells (HUVEC) by analysis of the production of interleukin-8 (IL-8), monocyte chemotactic protein 1 (MCP-1), and soluble intercellular cell adhesion molecule 1 (sICAM-1). Sequence analysis of omp1 of C. pneumoniaeA-03, compared to prototype strains TW-183 and AR-39, revealed five nucleotide changes …
