This study was done to assess the specificity and sensitivity of the DNA amplification assays of ligase chain reaction (LCR) and polymerase chain reaction (PCR) on urine specimens to detect Chlamydia trachomatis infections in both male and female patients seen at a sexually transmitted diseases (STD) clinic in Singapore, compared with other diagnostic methods currently in use. A total of 100 pa...

The Gen-Probe PACE 2 assay (Gen-Probe Inc., San Diego, Calif.) was compared with culture for the detection of Neisseria gonorrhoeae in endocervical specimens that were mailed to the laboratory. During mail transport, the specimens were exposed to extremes of hot and cold weather for several days before arriving in the laboratory. Specimens on culture plates deteriorated during transport, as evi...

the objective of this study was to determine the prevalence and distribution of chlamydia trachomatisgenotypes in shiraz, iran. two hundred twelve cervical swab samples were collected from women attendingshahid motahari polyclinic in shiraz, iran. the endocervical specimens were screened for c. trachomatis byplasmid pcr. genotyping was performed in c. trachomatis-positive samples by nested pcr ...

OBJECTIVES The aim of this study was to establish the prevalence of sexually transmitted infections including human immunodeficiency virus (HIV) infection in women with Bartholin's gland abscess. SETTING Gynaecology Clinic of King Edward VIII Hospital, a large urban, referral hospital for the province of Kwa-Zulu Natal, serving an underprivileged population. METHODS Thirty consecutive women...

To assess associations of nonulcerative sexually transmitted diseases (STDs) with human immunodeficiency virus (HIV)-susceptible leukocytes on female genital mucosa, cervicovaginal specimens from 32 HIV-negative STD clinic patients with gonorrhea, chlamydial infection, or trichomoniasis were compared with specimens from 32 clinic patients without these infections. Twenty-eight patients had sing...

The performance characteristics of the new signal amplification-based Hybrid Capture (HC) II CT-ID test system (Digene, Silver Spring, Md.) with endocervical specimens were compared to those of tissue culture and PCR (AMPLICOR CT PCR; Roche Molecular Systems, Branchburg, N.J.) for detection of Chlamydia trachomatis in 587 women. HC II CT-ID identified 62 of 65 confirmed C. trachomatis-positive ...

Six hundred one endocervical specimens were analyzed for Chlamydia trachomatis by the APTIMA Combo 2 assay and evaluated for columnar epithelial cell adequacy by direct fluorescent-antibody staining. With 5.5% positive adequate and 7.8% positive inadequate specimens (P=0.27), the study suggested no difference in positivity rates due to specimen adequacy when this amplified technology was used.

Screening for sexually transmitted diseases (STDs) in a greater proportion of sexually active patients has become an accepted protocol by most health care providers. The purpose of this study was to compare the current test methods for detection of Chlamydia trachomatis used at the University of South Alabama, the PACE 2 assay (Gen-Probe) and the Clearview EIA (Wampole Laboratories), with two a...

A cytobrush was compared with a cotton-tipped aluminium shafted swab for the collection of 2024 paired endocervical specimens for the culture of Chlamydia trachomatis. There was no significant advantage with the use of either device with respect to the number of positive specimens detected or the number of inclusions present in positive specimens. However, the use of cytobrushes resulted in an ...

OBJECTIVES To determine the prevalence and correlates of Mycoplasma genitalium (MG) infection among men and women, determine the prevalence of gene mutations conferring resistance and compare test performance of female specimen types. METHODS A cross-sectional study was conducted on specimens collected for gonorrhoea (NG, Neisseria gonorrhoeae) and chlamydia (CT, Chlamydia trachomatis) among ...
