In a recent article, Bas and collaborators compared different serological methods to detect chlamydial antibodies in patients with Chlamydia trachomatis infections and healthy blood donors (1). Using the Labsystems enzyme immunoassay (EIA) for C. pneumoniae, no cross-reaction between C. trachomatis and C. pneumoniae was found. However, Gnarpe and collaborators recently showed cross-reactions be...

A total of 201 endocervical specimens were obtained from patients with a clinical or epidemiological history suggestive of chlamydial infection. These specimens were tested by DNA probe (Gen-Probe, San Diego, Calif.) and the IDEIA III (Boots-Celltech, Berkshire, United Kingdom) monoclonal antibody enzyme immunoassay and compared with cell culture for detection of Chlamydia trachomatis. Discrepa...

The aetiology of inflammatory bowel disease is at present obscure, but there is evidence that transmissible agents such as bacteria or viruses may be associated with this condition.' 4 Chlamydia trachomatis agents are known to infect the rectum5 6 and lymphogranuloma venereum (LGV) serotypes can cause chronic inflammation with fistula formation similar to manifestations of Crohn's disease. Prev...

Chlamydia trachomatis proteins were electrophoresed and then transferred to nitrocellulose paper to detect chlamydial proteins which bind to eucaryotic cell membranes. Resolved polypeptides of C. trachomatis serovars J and L2 were reacted with iodinated HeLa cell membranes and autoradiographed. Infectious elementary bodies of both serovars possess 31,000- and 18,000-dalton proteins which bind t...

The role of Chlamydia trachomatis in pelvic inflammatory disease (PID) diagnosed without laparoscopy was assessed by measuring antichlamydial antibodies in the patient's serum and by comparing the results with those in patients with uncomplicated non-specific genital infection (NSGI) and gonorrhoea and in non-infected controls. A modified microimmunofluorescence test was used. Patients with sev...

\s=b\Serum samples from 184 Infants and children whose blood was drawn during a clinic visit were tested for antibody to Chlamydia trachomatis, Epstein-Barr virus, and cytomegalovirus. Lifetime illness history was obtained from clinic records. Fifteen percent had anti\p=n-\Ctrachomatis IgM antibody. Anti\p=n-\Ctrachomatis IgM without IgG was significantly associated with upper respiratory tract...

Two adult male baboons (Papio cynocephalus) were infected by urethral catheter with a Type D strain of Chlamydia trachomatis isolated from a male patient with nongonococcal urethritis. Chlamydial organisms were shed from the urethra for about 90 days and serum antibody developed. Intraurethral re-inoculation of homologous and heterologous (Type I) strains of Chalmydia, 4 and 11 months later, re...

Chlamydia pneumoniae is frequently found in atherosclerotic lesions, and high titers of specific antibodies are associated with increased risk for acute myocardial infarction. However, a causative relation has not been established yet. We performed a prospective study of 93 patients undergoing percutaneous transluminal coronary angioplasty (PTCA) to investigate whether angioplasty influences Ch...
