The natural history of chlamydia is variable and may include persisting asymptomatic infection, complications, or spontaneous resolution before treatment. Reinfection is common. We evaluated whether spontaneous resolution was associated with decreased reinfection in women returning for treatment of a positive chlamydia screening test. At enrollment, participants were tested for chlamydia, treat...

infertility in famale is one of the most important sequela of genital infection with chlamydia trachomatis, mycoplasma hominis and ureaplasma urealyticum. in the present study the frequency of these bacteries was studied in 125 infertile female by direct and indirect immunofluorscence tests and culture method and compared with 250 normal population. mycoplasma hominis was isolated from 32 (35.6...

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...

The importance of antibody-mediated immunity in primary and secondary Chlamydia trachomatis genital tract infections was examined by using a definitive model of B-cell deficiency, the microMT/microMT gene knockout mouse. Vaginally infected B-cell-deficient microMT/microMT mice developed a self-limiting primary infection that was indistinguishable from infection of control C57BL/6 mice. Sera and...

BACKGROUND Chlamydia is one of the most common sexually transmitted diseases in humans worldwide, causing chronic lesions in the reproductive tract. Due to its often asymptomatic course, there is limited knowledge about the initial changes in the genital tract following infection. This study employs a novel sexually mature minipig model to investigate the initial histopathological changes follo...

Inflammatory arthritis can follow urogenital infection with Chlamydia trachomatis, the most prevalent sexually transmitted bacterial infection in the US. It can also follow infections with a respiratory form of Chlamydia which is almost ubiquitous. Clinicians often don’t recognize this, and even when they do, may not know that these forms of arthritis seldom respond to standard antibiotic thera...

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 ...

Chlamydiae are intracellular, gram-negative, and prokaryotic microorganisms. Capable of causing disease in many mammalian avian species, there three types that cause humans: Chlamydia trachomatis, pneumoniae, psittaci. Among the chlamydia C. trachomatis is most studied encountered type because it a leading trachoma sexually transmitted diseases. known pathogen genital tract, can also be routine...

OBJECTIVE Anal cancer is a rare tumor, which incidence is influenced by sexual behavior. The purpose of this paper is to verify the correlation between anal cancer and sexually transmitted diseases, such as HPV, HIV, Gonococci infection, Chlamydia infection, syphilis and others. METHODS All the internments due to anal cancer, HIV, HPV, syphilis, Gonococci infection, Chlamydia infection and ot...

Chlamydia trachomatis and Herpes Simplex Virus-2 (HSV-2) genital tract co-infections have been reported in humans and studied in vitro but the clinical consequences are unknown. Limited epidemiologic evidence suggests that these co-infections could be more severe than single infections of either pathogen, but the host-pathogen interactions during co-infection remain uncharacterized. To determin...
