PURPOSE To evaluate the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in women undergoing assisted reproduction in a public reference service in the midwestern region of Brazil. METHODS A cross-sectional study was conducted on 340 women aged from 20 to 47 years with a history of infertility, undergoing assisted reproduction techniques. Infections with Chlamydia trachomatis and...

BACKGROUND We noted a marked increase in Chlamydia trachomatis (CT) infections in the Capital Health Region of NS coincident with substitution of a PCR for an enzyme immunoassay (EIA). We reviewed our experience to determine the cost of switching and the impact on the number of new infections diagnosed. METHODS Information on the number of EIA and PCR tests performed on women was retrieved fr...

BACKGROUND Chlamydia trachomatis is the most common bacterial sexually transmitted infection (STI) in the United States (U.S.) [1] and remains a major public health problem. We determined the cost- benefit of screening all pregnant women aged 15-24 for Chlamydia trachomatis infection compared with no screening. METHODS We developed a decision analysis model to estimate costs and health-relate...

The prevalence and clinical features of Chlamydia trachomatis infection were studied in men with nongonococcal urethritis (NGU), in their female sexual partners, and in other women. Of 92 patients with NGU, 36 (39%) were chlamydia-positive; although all had symptoms of urethritis, fewer than half had evident discharge. Clinical features of chlamydia-positive and chlamydia-negative NGU were indi...

Chlamydia trachomatis (CT) is one of the major bacterial agent of the sexually transmitted diseases (STDs) worldwide. It is a causative agent of urogenital, ocular and pneumonic infections, causing annually 92 million new infections worldwide. It is responsible for a wide range of infections, including trachoma (a chronic conjuctivitis, which is the leading preventable cause of blidness worldwi...

Background: We designed a prospective study to assess the role of Chlamydia in secondary infertility Materials and Methods: 40 women with secondary infertility and 30 term healthy pregnant women of similar age composition were studied for past and present chlamydia trachomatis infection. Women attending the outpatient department of Obstetrics and Gynaecology with complaint of secondary infertil...

BACKGROUND Infection by Chlamydia trachomatis (CT) is the most prevalent sexually transmitted infection (STI) world wide. The most frequently used diagnostic test for CT is a nucleic acid amplification test (NAAT), which is highly sensitive and specific. To further shorten time delay until diagnosis has been made, in order to prevent CT spread, the use of point-of-care (POC) tests may be the wa...

Chlamydia trachomatis is an important human pathogen that replicates inside the infected host cell in a unique vacuole, the inclusion. The formation of this intracellular bacterial niche is essential for productive Chlamydia infections. Despite its importance for Chlamydia biology, a holistic view on the protein composition of the inclusion, including its membrane, is currently missing. Here we...

Chlamydia trachomatis infection is the most common bacterial sexually transmitted disease in the United States. Chlamydia infections that ascend to the upper genital tract can persist, trigger inflammation, and result in serious sequelae such as infertility. However, mouse models in which the vaginal vault is inoculated with C. trachomatis do not recapitulate the course of human disease. These ...

OBJECTIVES To identify Chlamydia trachomatis via polymerase chain reaction and a direct fluorescent antibody assay in patients with vernal keratoconjunctivitis while comparing the efficacies of both tests for detecting Chlamydia trachomatis in these conditions. METHODS Conjunctival scraping samples were obtained from 177 patients who were divided into two groups: a vernal keratoconjunctivitis...
