Introduction: Chlamydia trachomatis causes many infections, including eye infections. They manifest as inclusion conjunctivitis and trachoma. The agent is transmitted by dirty hands, eyeliners, medical instruments and via swimming-pool water or, in neonates, by passage through an infected birth canal. Due to the nonspecific clinical features at the beginning of the infection and delayed application of symptomatic, anti-allergic and non-specific antibiotic therapy, Chlamydia aetiology is usually established only after laboratory diagnosis in the chronic stage of infection.
Objective: Determining the frequency of Chlamydia trachomatis antigen in conjunctival and genital samples of adult patients with chronic conjunctivitis in Nisava district.
Methods: Our retrospective study was carried out on 116 patients (63 female and 53 male) with clinical signs and symptoms of chronic conjunctivitis. Chlamydia trachomatis antigen was detected by a direct immunofluorescence test with labelled monoclonal antibodies.
Results: From a total of 116 examined patients in 37 patients Chlamydia trachomatis antigen was detected; 17 female and 20 male. Thirty-three of the patients had a bilateral infection and four unilateral. Among 24 patients who were also tested for Chlamydia trachomatis antigen collected by ocular and genital swabs, 19 had conjunctivitis associated with urethritis/vaginitis.
Conclusion: The studied group of patients showed that the common cause of the chronic conjunctivitis were bacteria, but predominantly Chlamydia trachomatis. In most cases Chlamydia infection occurred bilaterally. The majority of patients had eye Chlamydia infection associated with genital Chlamydia infection. There was no statistically significant difference in the presence of the disease regarding gender.

Background: We aimed to determine the household distribution and viability of Chlamydia trachomatis (Ct) from the eyes, face, and hands during the initial two visits of a year-long fortnightly cohort study in geographically defined adjacent households.
Methods/findings: We enrolled 298 individuals from 68 neighbouring households in Shashemene Woreda, Oromia, Ethiopia. All individuals above 2 years of age residing in these households were examined for signs of trachoma.

is an obligate intracellular bacterial pathogen that develops within a membrane-bound vacuole called an inclusion. Throughout its developmental cycle, modifies the inclusion membrane (IM) with type III secreted (T3S) membrane proteins, known as inclusion membrane proteins (Incs). Via the IM, manipulates the host cell to acquire lipids and nutrients necessary for its growth.

We use a TNF-overexpressing Crohn's disease (CD) model (Tnf ), which typically presents in the terminal ileum (TI), to investigate how environmental factors interact with the host's immune susceptibility to drive region-specific disease. We identified , an intracellular bacterium and murine counterpart to the human sexually transmitted , as necessary and sufficient to trigger disease manifestation in the ascending colon (AC), another common site of human CD.

Objectives: Chlamydia trachomatis is the most commonly diagnosed bacterial sexually transmitted infection (STI) worldwide. Diagnosis relies on nucleic acid amplification techniques, such as PCR, which does not distinguish between viable pathogens and residual bacterial DNA, leading to potential overdiagnosis and overtreatment. PCR with confirmation of pathogen viability has not been widely explored in the STI field.
