Chlamydia pneumoniae infection generally starts in the respiratory tract and probably disseminates systemically in the blood stream within alveolar macrophages. We investigated the prevalence of C. pneumoniae DNA in peripheral blood mononuclear cells (PBMC) in patients with acute ischaemic heart disease. Samples of blood were obtained from 93 consecutive(More)
During recent years many seroepidemiological studies have been published about Lyme borreliosis in various European countries. This paper presents a review of these studies to clarify the geographical incidence of the infection by B. burgdorferi in Europe and particularly in Italy. Data of Lyme disease seroprevalence has been established in European(More)
BACKGROUND Previous works have suggested an association between Chlamydia pneumoniae infection and coronary heart disease. We evaluated the prevalence of C. pneumoniae infection in patients with acute myocardial infarction (AMI) and coronary heart disease (CHD). METHODS AND RESULTS Ninety-eight patients with AMI, 80 patients with CHD, and 50 control(More)
There is a growing interest in indoor air quality for a better quality environment both at home and at work because many people spend at least 80% of their time indoors. The aim of our study was to evaluate the indoor concentration of airborne bacteria and fungi in a University auditorium, in an office of public buildings and in an apartment in the presence(More)
Chlamydia pneumoniae, an intracellular bacterial pathogen, is known as a leading cause of human respiratory tract infections worldwide. Over the last decade, several reports in the literature have suggested that infection with C. pneumoniae may contribute to the pathogenesis of atherosclerosis. In order to play a causative role in chronic disease, C.(More)
Six Archaea belonging to the phylum Euryarchaeota were previously analyzed with respect to stringent control. Only one of the strains studied was shown to possess Bacteria-like stringent control over stable RNA accumulation; ppGpp and pppGpp production was totally lacking in all Archaea analyzed. To broaden our knowledge of stringent control in the Archaea,(More)
The involvement of Chlamydia pneumoniae in the pathogenesis of atherosclerosis has been suggested by numerous seroepidemiological, in vivo and in vitro studies. In particular, it has been shown that C. pneumoniae is able to promote the accumulation of low-density lipoproteins into macrophages, thus facilitating foam cell formation. The aim of our study was(More)
Sirs: Since the initial report [1] suggesting an association between infection with Chlamydophila pneumoniae (C. pneumoniae) and multiple sclerosis (MS), a possible involvement of this common respiratory pathogen as etiologic agent has been investigated with conflicting results [2–8]. C. pneumoniae is presumed to play a role for its ability to cause a(More)
The aim of this study was to evaluate the seroprevalence of B. burgdorferi and A. phagocytophila in populations of workers from 4 Italian regions, known to be exposed to tick bites. A total of 712 serum samples collected were divided as follows: 387 samples were obtained from workers at risk for tick bites and 325 from individuals that were not considered(More)
Several studies have attempted to relate the C. pneumoniae-mediated inflammatory state with atherosclerotic cardiovascular diseases, providing inconsistent results. Therefore, we performed a meta-analysis to clarify whether C. pneumoniae may contribute to the pathogenesis of atherosclerosis by enhancing inflammation. 12 case-control, 6 cross-sectional, and(More)
