an amplification polymerase chain reaction (pcr) test for the direct detection of chlamydia trachomatis in urethral and endocervical swab specimens from symptomatic and asymptomatic women and men were compared to standard culture technique. during 6 months, 300 endocervical swab specimens from 205 asymptomatic women (64.4%) and 95 symptomatic women (31.6%), and 187 urethral swab specimens from ...

Several studies have demonstrated that the sensitivity of a commercially available PCR test for the detection of Chlamydia trachomatis (Roche Diagnostics) is affected by the cellular quality of the endocervical swab specimens. The cellular adequacies of 1,633 female endocervical swab specimens were assessed and compared with the results of C. trachomatis detection obtained by ligase chain react...

The aim of this study was to determine whether a patient's endocervical swab specimen can be transported in first void urine (FVU) as combined specimens for the detection of Mycoplasma genitalium by real-time PCR. The study also compared two different DNA extraction methods for observation of possible PCR inhibition. Three specimens, one endocervical swab specimen transported in 2-SP medium, on...

Screening of urine specimens from men for Chlamydia trachomatis infection by a commercial PCR assay (AMPLICOR C. trachomatis Test; Roche Diagnostic Systems, Inc., Branchburg, N.J.) is a sensitive and specific noninvasive diagnostic assay. Since screening of women for C. trachomatis infection with the AMPLICOR C. trachomatis Test has been limited to use with endocervical swab specimens, we condu...

AIMS To compare the performance of a new generation dual amplified enzyme immunoassay (EIA) with a molecular method for the diagnosis of Chlamydia trachomatis, using a range of urogenital samples, and to assess the reliability of testing self collected vaginal specimens compared with clinician collected vaginal specimens. METHODS Two population groups were tested. For the first population gro...

A coamplification PCR test for the direct detection of Neisseria gonorrhoeae and Chlamydia trachomatis in urethral and endocervical swabs and urine samples from men and women was compared to standard culture techniques. Processed specimens were amplified in single reaction tubes containing primers for both organisms, and PCR products were detected by a colorimetric microwell plate hybridization...

SUMMARY During 2 years, 212 patients with PID and 160 women with no sign of PIO (as control group) were selected for the detection of aerobic an<l anaerobic bacteria and possible cause of the disease. Specimens from 58 patients and 60 controls were taken by laparoscopy and laparotomy, 154 patients and 100 controls by swabs from endocervical canal. From laparoscopy and laparotomy group(58) 9 ...

Detection of chlamydial infections depends on the sensitivity of the techniques used. Variables include the number of body sites sampled, the number of samples obtained, and the number of passages in tissue culture. To assess these factors, microdilution plate cultures with a single blind passage were performed on specimens from 10,291 men and women attending a sexually transmitted disease clin...

Levels of HIV-1 RNA in endocervical specimens fluctuate with the menstrual cycle, suggesting that cell-free HIV-1 levels may vary during the cycle, which could influence infectivity. Here, we examined daily changes in endocervical HIV-1-infected cells during 1 cycle. There were significant positive associations between the number of days from the luteinizing hormone surge and the number of HIV-...

OBJECTIVE To compare endocervical brushing with endocervical curettage with respect to diagnostic yield by histology and patient discomfort. METHODS Nonpregnant women referred for colposcopy because of abnormal Papanicolaou test results were randomized to endocervical sampling with either a metal curette (endocervical curettage [ECC]) or an endocervical brush. Extensive endocervical canal bru...
