In this report, we show that the Chlamydia trachomatis-specific CD8+ T cell antigen class I accessible protein-1 (Cap1) is expressed during the early stages of the C. trachomatis developmental cycle. We provide additional evidence suggesting that Cap1 may be important in early immune recognition of the organism. Understanding the temporal and spatial expression of CD8+ T cell antigens such as C...
Experimental ocular infection of specific-pathogen-free cats with the feline pneumonitis strain of Chlamydia psittaci produced an acute, severe conjunctivitis characterized by blepharospasm, conjunctival hyperemia, chemosis, and ocular discharge. Organisms were recovered from the conjunctiva for several weeks, and persistent genital and gastrointestinal infection also resulted from the ocular i...
OBJECTIVE To evaluate a new enzyme immuno assay, Antigenz Chlamydia, for the detection of chlamydial antigen in urogenital samples using cell culture as the gold standard for comparison and direct immuno fluorescence to aid resolving the discrepancies. SUBJECTS 212 men and 303 women attending an STD clinic and 404 women of child bearing age attending gynaecological clinics. RESULTS Sensitiv...
Chlamydia trachomatis is one of the main causes of Sexually Transmitted Diseases (STDs) such as prostatitis and epididymitis in men and cervicitis, endometriosis, vaginitis and ureogenital tract infections in women. Serological tests with sensitivities related to specific antigens are commonly used as routine laboratory tests for diagnosis of Chlamydia. In this research the Chlamydia Major O...
Immune adherence hemagglutination (IAHA) was compared to complement fixation (CF), using standard procedures, for serological testing of human sera with a number of commercially available antigens. The antigens included herpes simplex, measles, cytomegalo-, and influenza (type B) viruses, as well as Mycoplasma pneumoniae and Chlamydia psittaci (Chlamydia group). The IAHA test was found to be as...
Clearview Chlamydia (Unipath) is a rapid monoclonal antibody based latex immunodiffusion test for detecting chlamydial antigen in endocervical specimens. The assay does not require specialised equipment or extensive training and takes less than 30 minutes from sample to results. The clinical performance of Clearview Chlamydia was evaluated with 478 paired endocervical swabs from patients attend...
DNA fragment No. 13 from the C. psittaci pigeon strain, has been cloned in the plasmid pUC19. Hybridization analysis revealed that the fragment maintained a chlamydial common sequence. Furthermore, nucleotide sequencing identified two partial open reading frames (ORF), 675b. p. and 530b. p. Expression of ORFs revealed that the second ORF encoded 25KD polypeptide, whereas the first ORF did not p...
Genital chlamydial infections lead to severe upper reproductive tract pathology in a subset of untreated women. We demonstrated previously that tumor necrosis factor (TNF)-α-producing CD8(+) T cells contribute significantly to chlamydial upper genital tract pathology in female mice. In addition, we observed that minimal chlamydial oviduct pathology develops in OT-1 transgenic (OT-1) mice, where...
Ligase chain reaction (LCR) was compared with ACCESS immunoassay for detection of chlamydial infections in females. Despite efforts to improve ACCESS performance by evaluation of specimens that were in the test performance "grey zone," LCR remained more sensitive and was less expensive to perform. ACCESS had a sensitivity of 83.9%, a specificity of 99.7%, a positive predictive value of 96.3%, a...
Background. The aim of this study was to identify overall sexually transmitted diseases (STD) burden in HIV infected patients and determine compliance with sexual health screening and treatment based on CDC 2010 Guideline in our HIV clinic. Methods. This is a retrospective cohort study of all adult patients attending at least 2 visits at the University of Kansas Medical Center outpatient infect...
