Background: In high-incidence Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) settings, annual re-testing is an important public health strategy. Using baseline laboratory data (2009-10) from a cluster randomised trial in 67 remote Aboriginal communities, the extent of re-testing was determined, along with the associated patient, staffing and health centre factors. Methods: Annual testing was defined as re-testing in 9-15 months (guideline recommendation) and a broader time period of 5-15 months following an initial negative CT/NG test...

Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases. Our research pertains to the inhibitory effect and molecular mechanism of the chlamydiaphage capsid protein VP1 on the growth of Chlamydia trachomatis. In this research, the capsid protein VP1 of the guinea-pig conjunctivitis chlamydiaphage phiCPG1 was expressed, purified and identified, and then, it was applied to the cultivation of different serovars of Chlamydia trachomatis and Chlamydia psittaci. The inhibitory effect was observed in each serovar of Chlamydia trachomatis (D, E, F, G, H, I, K, and L2) and Chlamydia psittaci inoculated with VP1 protein...

Chlamydia trachomatis (CT) elementary body (EB) ELISA was used to investigate serum anti-CT IgG1 (long-lived response) and IgG3 (short-lived response indicating more recent infection) from treatment (enrollment) and 6-month follow-up visits in 77 women previously classified as having spontaneous resolution of chlamydia. 71.4% of women were IgG1+IgG3+, consistent with more recent chlamydia resolution. 15.6% were IgG3- at both visits, suggesting absence of recent chlamydia. Using EB ELISA, we demonstrated about one in six women classified as having spontaneous resolution of chlamydia might have been exposed to CT but not infected...

Conjunctivitis is a frequently diagnosed disease, usually caused by a virus. A less well-known cause is a chlamydia infection. This may result in missed diagnoses, delay of treatment and several complications. We present two cases of a persistent, therapy-resistant conjunctivitis in patients who were over 70 years of age. One patient had conjunctival follicles, characteristic of chlamydia conjunctivitis. The polymerase chain reaction tests of conjunctival samples from both patients were positive for chlamydia...

BACKGROUND: Proton pump inhibitors (PPIs) have been shown in cell culture to kill Trichomonas vaginalis (TV) at lower half maximal inhibitory concentration values than metronidazole (Flagyl), the most common medication used to treat the infection. However, there have been no previous clinical investigations to determine if PPIs are associated with reduced risk for TV. MATERIALS AND METHODS: We examined the records of female patients who received testing in the emergency department for TV, Neisseria gonorrhoea (GC), and Chlamydia trachomatis (CT) between 2010 and 2014 at two academic medical centers to determine if PPI and histamine type 2 receptor antagonist (H2RA) drugs were associated with TV and GC/CT infections...

Chlamydia trachomatis is the most prevalent sexually transmitted bacterial infection. However, whether Chlamydia trachomatis has a negative impact on sperm quality and male fertility is still controversial. Herein, we report the effects on sperm quality of the in vitro exposure of spermatozoa to Chlamydia trachomatis, and also the effects of male genital infection on male fertility using an animal model. Human and mouse sperm were obtained from healthy donors and cauda epididimys from C57BL/6 mice, respectively...

Chlamydia trachomatis remains a leading cause of bacterial sexually transmitted infections and preventable blindness worldwide. There are, however, limited in vitro models to study the role of host genetics in the response of macrophages to this obligate human pathogen. Here, we describe an approach using macrophages derived from human induced pluripotent stem cells (iPSdMs) to study macrophage-Chlamydia interactions in vitro. We show that iPSdMs support the full infectious life cycle of C. trachomatis in a manner that mimics the infection of human blood-derived macrophages...

BACKGROUND: Chlamydia species are obligate intracellular bacteria that infect a broad range of mammalian hosts. Members of related genera are pathogens of a variety of vertebrate and invertebrate species. Despite the diversity of Chlamydia, all species contain an outer membrane lipooligosaccharide (LOS) that is comprised of a genus-conserved, and genus-defining, trisaccharide 3-deoxy-D-manno-oct-2-ulosonic acid Kdo region. Recent studies with lipopolysaccharide inhibitors demonstrate that LOS is important for the C...

BACKGROUND: Pelvic inflammatory disease (PID) is an infection that affects 4% to 12% of young women, and is one of the most common causes of morbidity in this age group. The main intervention for acute PID is the use of broad-spectrum antibiotics which cover Chlamydia trachomatis, Neisseria gonorrhoeae, and anaerobic bacteria, administered intravenously, intramuscularly, or orally. In this review, we assessed the optimal treatment regimen for PID. OBJECTIVES: To assess the effectiveness and safety of antibiotic regimens used to treat pelvic inflammatory disease...

BACKGROUND: Chronic coronary artery disease has been associated, as a consequence of the local inflammatory reaction with previous or persistent infection with Chlamydia pneumoniae, which led to the investigation of the association of cardiovascular disease and previous infection with C. trachomatis and the role of cytokine profile (in situ) markers in the vascular system tissues. METHODS: Sixty-nine biopsies were collected for immunohistochemical analysis for the presence of IL-6, IL-8, TNF-α, IFN-γ, TGF-β, and IL-10, in 16 fragments from atheromatous plaques, 32 aorta fragments, and 21 valve fragments, using a tissue microarray technique for paraffin embedded tissues...

Genital infection by Chlamydia trachomatis (CT) is the most common bacterial sexually-transmitted disease worldwide. It causes serious reproductive health complications, including pelvic inflammatory disease and infertility. Stress is implicated as a risk factor for various infections; however, its effect on chlamydia genital infection is unknown. We previously showed that repeated exposure of mice to cold water results in increased severity of chlamydia genital infection. In the present study, cold water-induced stress resulted in: i) elevated levels of NE and EP in the spleen and genital tract of stressed mice; ii) elevated IL-1β, TNF-α, IL-6 and NO production in macrophage-rich peritoneal cells of mice; iii) supplement of NE in vitro exerts an immunosuppressive effect on splenic T cell production of cytokines; iv) decreased C...

The search for new nontraditional targets is a high priority in antibiotic design today. Bacterial membrane energetics based on sodium ion circulation offers potential alternative targets. The present work identifies the Na(+)-translocating NADH:ubiquinone oxidoreductase (Na(+)-NQR), a key respiratory enzyme in many microbial pathogens, as indispensible for the Chlamydia trachomatis infectious process. Infection by Chlamydia trachomatis significantly increased first H(+) and then Na(+) levels within the host mammalian cell...

The Planctomycetes-Verrucomicrobia-Chlamydiae (PVC) bacterial superphylum constitutes a broad range of organisms with an intriguing array of ultrastructural morphologies, including intracellular membranes and compartments and their corresponding complex genomes encoding these forms. The phylum Chlamydiae are all obligate intracellular bacteria and, although much is already known of their genomes from various families and how these regulate the various morphological forms, we know remarkably little about what is likely the deepest rooting clade of this phylum, which has only been found to contain pathogens of marine and fresh water vertebrates...

Annual chlamydia testing is recommended for all sexually active Australians aged 15-29 years; however, the testing rate is below recommended levels. Three surveys at a Melbourne music festival were conducted over 2012-14 to identify correlates of sexually transmissible infection (STI) testing among young people at risk of STIs. In total, 3588 participants were recruited; 72% reported having sex in the past year. Based on sexual behaviours, 38% of sexually active participants were classified as at risk of contracting STIs...
