Cervical swabs for Chlamydia culture were collected from 638 unselected women attending a sexually transmitted diseases clinic with a fresh complaint. Chlamydia were isolated from 76 (12 per cent.) of the women. When the results were related to the patients' diagnoses, Chlamydia were present in 44 per cent. of women with gonorrhoea and in 22 per cent. of women who were contacts of men with nons...

Further research is necessary to elucidate the pathogenesis of chlamydial PID. It is hoped that these endeavours will eventually lead to a vaccine to prevent not only chlamydia infection, but also chlamydia associated infertility, ectopic pregnancy, and chronic pelvic pain. In the meantime we need to develop strategies to prevent primary and secondary chlamydia infection and its sequelae. Recen...

Chlamydia spp. are obligate intracellular bacteria distributed all over the world, known to cause various forms of diseases in animals and humans. In the present study, a serological survey was conducted to detect the seroprevalence and risk factors associated with rabbit chlamydiosis in northeast China, including Liaoning province, Jilin province, Heilongjiang province, and Inner Mongolia Auto...

BACKGROUND Chlamydia trachomatis is a common, often recurring sexually transmitted infection, with serious adverse outcomes in women. Current guidelines recommend retesting after a chlamydia infection, but the optimum timing is unknown. We assessed the optimal retest interval after urogenital chlamydia treatment. METHODS A randomized controlled trial among urogenital chlamydia nucleic acid am...

Antimicrobial treatment of chlamydial infections is known to be of limited efficacy. In this study, effects of doxycycline (D), usually the drug of choice, were compared with the combined therapy of doxycycline and rifampicin (R) in a bovine model of respiratory Chlamydia psittaci infection. After intrabronchial inoculation of the pathogen, 30 animals were assigned to five groups (n = 6 per gro...

We previously reported that the IFN-β secreted by Chlamydia muridarum-infected murine oviduct epithelial cells (OE cells) was mostly dependent on the TLR3 signaling pathway. To further characterize the mechanisms of IFN-β synthesis during Chlamydia infection of OE cells in vitro, we utilized specific inhibitory drugs to clarify the roles of IRF3 and NF-κB on both early- and late-phase C. murida...

Asthma is a chronic respiratory disease whose etiology is poorly understood. Recent studies suggest that early-life respiratory infections with atypical bacteria may play an important role in the induction or exacerbation of chronic respiratory disease. The current study utilized a neonatal mouse ovalbumin (OVA) sensitization model of asthma to determine the course of early-life respiratory tra...

Chlamydia species are susceptible in vitro to certain antibiotics, and various tetracyclines, macrolides, and fluoroquinolones are used for the treatment of Chlamydia trachomatis infections. Less is known about the in vitro susceptibility and chemical response to infection with Chlamydia pneumoniae. Results of in vitro studies from the literature and from my laboratory employing a tissue cultur...

Chlamydia trachomatis is a common cause of sexually transmitted disease which can cause severe consequences. Effective prevention requires knowledge of prevalence of infection in order to target interventions in a cost-effective manner. To determine the prevalence of chlamydial infection in Mashhad, northeastern Islamic Republic of Iran, this study was performed among male patients with urethri...
