BACKGROUND The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated P...

OBJECTIVES Pelvic inflammatory disease (PID) is an important cause of female infertility and can occur when micro-organisms such as chlamydia or gonorrhoea ascend to the upper genital tract. PID has been used as an outcome measure in chlamydia screening trials; however, few data have quantified the PID burden that could be avoided by preventing chlamydia. We estimated the population attributabl...

BACKGROUND Our study aimed to describe the concordance of chlamydia infections of the rectum and urethra in men who have sex with men (MSM) and their male partners. METHODS This was a cross-sectional study of chlamydia in MSM and their male sexual partners both attending Melbourne Sexual Health Centre (MSHC), Australia, between February 2011 and March 2015. We excluded partnerships where test...

Enzootic ovine abortion is caused by Chlamydia abortus and may result in abortion among small ruminants during the last 2-3 weeks of pregnancy. Enzootic abortion is diagnosed by isolation of the agent or detection of its nucleic acid in the products of abortion or vaginal excretions of freshly aborted females. Isolation of chlamydial agents in cell culture is the gold standard, so in the presen...

Methanol, used for fixing chlamydia organisms to microscopic slides, was shown to eliminate the antigenic reactivity of Chlamydia pneumoniae elementary bodies with fluorescent antibodies. Acetone fixation had no adverse effect. Chlamydia trachomatis and Chlamydia psittaci were not affected by methanol fixation. The effect of methanol on C. pneumoniae is another characteristic that differentiate...

BACKGROUND A significant number of studies on pig farms and wild boars worldwide, demonstrate the endemic presence of Chlamydia suis in pigs. However, the zoonotic potential of this pathogen, phylogenetically closely related to Chlamydia trachomatis, is still uninvestigated. Therefore, this study aims to examine the zoonotic transmission in a Belgian pig abattoir. METHODS Presence of Chlamydi...

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...

Introduction: Chlamydiosis is a worldwide zoonotic disease caused by different microorganisms in the order Chlamydiales. The aim of this study was to detect and determine the prevalence of Chlamydia infection in pet and zoo reptiles in Tehran, Iran. Materials and Methods: In a period of 10 months from April 2015 to February 2016, swab samples were collected from cloaca and conjunctiva of 130 pe...

BACKGROUND Chlamydia trachomatis is a common sexually transmitted infection that can have serious consequences. It is universally agreed that screening for chlamydia infection should be offered to sexually active young women. We undertook a literature review to document the views, attitudes and opinions of women about being screened, tested and diagnosed with Chlamydia trachomatis. METHODS On...

OBJECTIVE To evaluate the performance of a new Chlamydia Rapid Test with vaginal swab specimens as a potential tool for chlamydia diagnosis and screening. DESIGN Performance evaluation study. Settings A young people's sexual health centre (site 1) and two genitourinary medicine clinics (sites 2 and 3) in the United Kingdom. PARTICIPANTS 1349 women aged between 16 and 54 attending one of the...
