Chlamydia pneumoniae, Mycoplasma pneumoniae, and Legionella pneumophila in elderly patients with stroke (C-PEPS, M-PEPS, L-PEPS): a case-control study on the infectious burden of atypical respiratory pathogens in elderly patients with acute cerebrovascular disease.

Background And Purpose: Multiple studies have suggested an association between Chlamydia pneumoniae and Mycoplasma pneumoniae infection and cardiovascular disease. We investigated whether the risk of cerebrovascular disease is associated with Legionella pneumophila infection and the aggregate number/infectious burden of these atypical respiratory pathogens.

Methods: One hundred patients aged >65 years admitted with acute stroke or transient ischemic attack (TIA) and 87 control patients admitted concurrently with acute noncardiopulmonary, noninfective conditions were recruited prospectively.

Mycoplasma pneumoniae in elderly patients with stroke. a case-control study on the seroprevalence of M. pneumoniae in elderly patients with acute cerebrovascular disease - the M-PEPS Study.

Background And Purpose: Previous studies have suggested certain infections as potential risk factors for stroke. Chlamydia pneumoniae, an atypical respiratory pathogen, has been linked to atherosclerotic vascular diseases. Mycoplasma pneumoniae, another atypical respiratory micro-organism, can rarely cause stroke.

The reproducibility of an enzyme-linked immunosorbent assay for detection of Chlamydia pneumoniae-specific antibodies.

With use of an enzyme-linked immunosorbent assay (ELISA), Chlamydia pneumoniae immunoglobulins were detected in a consecutive series of patients' sera (n = 122 for IgA and IgG; n = 138 for IgM). When the ELISA tests were repeated, the percentage disagreements were 12%, 16% and 10% for C. pneumoniae IgA, IgG and IgM, respectively.

Chlamydia pneumoniae in elderly patients with stroke (C-PEPS): a case-control study on the seroprevalence of Chlamydia pneumoniae in elderly patients with acute cerebrovascular disease.

Background And Purpose: Multiple studies have suggested an association between Chlamydia pneumoniae infection and atherosclerotic vascular disease. We investigated whether serological markers of C. pneumoniae infection were associated with acute stroke or transient ischaemic attack (TIA), exclusively in elderly patients.

Human enteric pathogens identified in a London teaching hospital and a rural public health laboratory: 1994.

Two microbiology laboratories, one serving an inner city hospital and one a rural public health laboratory, collected data on the outcome of examining faecal specimens in 1994. Overall, 6.7% of the investigations were positive, but the rates were lower for hospital inpatients, for recently described pathogens, and in the absence of relevant clinical details; rates were higher for patients with a history of foreign travel.
