No analysis has been carried out on the impact of Chlamydia in pediatric patients with arthritis. The present study was conducted to investigate whether Chlamydia trachomatis and Chlamydia pneumoniae could be identified as a triggering infection in 33 pediatric patients including adolescents with acute joint disorders by using an extensive laboratory approach. Synovial fluid, nasopharyngeal sec...
Taxonomy The order chlamydiales has one family, chlamydiaceae, and one genus, chlamydia. Currently four species are recognized, Chlamydia trachomatis, Chlamydia pneumoniae, Chlamydia psittaci , and Chlamydia pecorum. To date, 19 different Chlamydia trachomatis serovars (41) and several Chlamydia psittaci serovars are known (6 avian (65), 9 mammalian (29)), but only one Chlamydia pneumoniae (40,...
OBJECTIVES Using polymerase chain reactions, this study aimed to evaluate the incidence of neonatal chlamydial conjunctivitis in our region of Hong Kong and explore any association between such conjunctivitis and nasopharyngeal colonisation with Chlamydia trachomatis. DESIGN Prospective epidemiological study. SETTING Regional hospital, Hong Kong. PATIENTS Consecutive patients with neonata...
Chlamydia trachomatis proteins were electrophoresed and then transferred to nitrocellulose paper to detect chlamydial proteins which bind to eucaryotic cell membranes. Resolved polypeptides of C. trachomatis serovars J and L2 were reacted with iodinated HeLa cell membranes and autoradiographed. Infectious elementary bodies of both serovars possess 31,000- and 18,000-dalton proteins which bind t...
BACKGROUND The WHO seeks to control trachoma as a public health problem in endemic areas. Achham District in western Nepal was found to have TF (trachoma follicular) above 20% in a 2006 government survey, triggering 3 annual mass drug administrations finishing in 2010. Here we assess the level of control that has been achieved using surveillance for clinical disease, ocular chlamydia trachomati...
Natural immunity against obligate and/or facultative intracellular pathogens is usually mediated by both humoral and cellular immunity. The identification of those antigens stimulating both arms of the immune system is instrumental for vaccine discovery. Although high-throughput technologies have been applied for the discovery of antibody-inducing antigens, few examples of their application for...
A total of 803 endocervical samples were obtained from females with clinical or epidemiological histories suggesting chlamydia infection. These specimens were tested by IDEIA III and cell culture for the presence of Chlamydia trachomatis. After resolution of discrepant results by direct fluorescent-antibody staining of pelleted cell culture transport materials, IDEIA III demonstrated sensitivit...
C3H (H-2(k)) mice are susceptible to a vaginal challenge with human strains of Chlamydia trachomatis and thus are a useful strain for testing potential Chlamydia vaccine candidates. However, C3H mice are fairly poor responders in terms of the level of antibody resulting from immunization with potential protective peptides representing variable domains (VDs) of the major outer membrane protein (...
Chlamydia trachomatis was found to be the aetiological agent of endometritis in three women with concomitant signs of salpingitis. All patients developed a significant antibody response to the organism. Chlamydia were recovered from aspirated uterine contents of two patients and darkfield examination of histological sections showed chlamydial inclusions in endometrial cells in one patient. Thus...
