An association of Chlamydia pneumoniae with atherosclerosis and coronary heart disease has been determined epidemiologically and by the detection of C. pneumoniae organisms in atherosclerotic lesions in both humans and animal models of atherosclerosis. Previously, it has been shown that C. pneumoniae is capable of replicating in cell types found within atheromatous lesions, viz., endothelial ce...
Some, but not all, Chlamydia spp. are predicted to encode a homolog of ArgR, a master regulatory molecule that modulates arginine biosynthesis and catabolism in bacteria in response to intracellular arginine levels. While genes for arginine biosynthesis are apparently missing in Chlamydia, a putative arginine transport system encoded by glnP, glnQ, and artJ is present. We found that recombinant...
Chlamydia are Gram negative obligate intracellular bacteria of eukaryotic cells and have a unique developmental cycle consisting of formation of infectious particle called elementary body and non-infectious particle called reticulate body. They are included in the order Chlamydiales and the order Chlamydiales belongs to the class Chlamydiae, phylum Chlamydiae, domain bacteria. The genus Chlamyd...
OBJECTIVE To investigate the current status of atypical pathogen associated infections in community-acquired pneumonia (CAP) in adults, and their clinical attributes. METHODS Clinical data, sputum specimens from acute phase, and paired sera from acute- and convalescent-phases of CAP in 153 adult patients were collected from May 2005 to May 2008 in multiple medical centers. Chlamydia pneumonia...
The associations between inhaled corticosteroid (ICS) use and pulmonary infections remains controversial. Chlamydia pneumoniae (C. pneumoniae) accounts for asthma exacerbations; however, there are no data regarding ICS effects on C. infections. Thus, we investigated whether fluticasone propionate (FP) or budesonide (BUD) could affect infection in vitro vivo, focusing the possible mechanisms tha...
UNLABELLED OBJECTIVE--To study the clinical characteristics of respiratory tract illness caused by Chlamydia pneumoniae. DESIGN -Prospective clinical, bacteriologic, and serologic study. Secondarily, a matched comparison of patients with and without evidence of C pneumoniae infection (serologic titers greater than or equal to 1:64 and less than 1:16, respectively). SETTING --Four primary ca...
