AI Article Synopsis
- Infection with Chlamydia pneumoniae, strain TWAR, has been linked to atherosclerotic cardiovascular disease through various studies.
- Serological studies in Finland and the U.S. show a significant connection between TWAR antibodies and atherosclerosis in coronary and carotid arteries.
- Morphological and molecular studies have detected C. pneumoniae in plaque (atheroma) but not in normal arteries, using advanced techniques like electron microscopy and specific DNA tests.
Article Abstract
Infection with Chlamydia pneumoniae, strain TWAR, has been associated with atherosclerotic cardiovascular disease in two types of investigations, seroepidemiological and morphological-molecular. A series of seroepidemiological studies from Finland and the United States have shown a statistically significant association between several types of TWAR antibody, including immune complexes, and atherosclerotic disease of the coronary and carotid arteries. The morphological-molecular studies have shown the C. pneumoniae organism in atheroma of the coronary arteries, and aorta but not in normal arteries. The presence of the organism in atheroma has been demonstrated by electron-microscopy, immunocytochemical staining with TWAR-specific monoclonal antibody and by the polymerase chain reaction for TWAR-specific DNA. The aetiological or pathogenic significance of the association of C. pneumoniae and atherosclerotic disease remains to be determined.

Unlabelled: Respiratory tract infections are major global health issues that require rapid and accurate diagnostic methods. Multiplex quantitative PCR (qPCR) is commonly used for pathogen detection in respiratory samples. However, the optimal specimen selection for detecting bacterial pathogens is not well-explored.

Background: This study examines the distribution characteristics of pathogenic bacteria in respiratory infections and their relationship with inflammatory markers to guide clinical drug use.
Methods: We selected 120 patients with lower respiratory tract infection in the electronic medical record system of Xinjiang Provincial People's Hospital from March 2019 to March 2023 for a case-control study. Using Indirect Immunofluorescence Antibody test(IFA), blood routine, C-reactive Protein (CRP), and High-sensitivity C-reactive Protein(hsCRP), we detected nine respiratory pathogens (Respiratory syncytial virus; Influenza A virus; Influenza B virus; Parainfluenza virus; Adenovirus; Mycoplasma pneumoniae; Chlamydia pneumoniae; Legionella pneumophila type 1; Rickettsia Q) in all patients and analyzed their distribution and correlation.

Background: Primary biliary cholangitis (PBC) is a cholestatic, autoimmune liver disease with the presence of characteristic autoantibodies. The aim of the work was to determine the level of antibodies directed against bacterial antigens: (anti-anti), (anti-), (anti- ) and () in sera of PBC patients. We also performed studies on the impact of the bacterial peptides on the specific antigen-antibody binding.
