Lipooligosaccharide is required for the generation of infectious elementary bodies in Chlamydia trachomatis.
Lipopolysaccharides (LPS) and lipooligosaccharides (LOS) are the main lipid components of bacterial outer membranes and are essential for cell viability in most Gram-negative bacteria. Here we show that small molecule inhibitors of LpxC [UDP-3-O-(R-3-hydroxymyristoyl)-GlcNAc deacetylase], the enzyme that catalyzes the first committed step in the biosynthesis of lipid A, block the synthesis of L...
متن کاملSmall numbers of Chlamydia trachomatis elementary bodies on slides detected by the polymerase chain reaction.
A method is described in which smears on slides, which had been examined previously in a direct fluorescence antibody (DFA) test for Chlamydia trachomatis, were tested by the polymerase chain reaction (PCR). Twenty four (73%) of 33 smears which contained fewer than 10 elementary bodies when examined by the DFA test were positive by the PCR. Of the nine negative smears, seven contained only one ...
متن کاملLactobacillus crispatus inhibits the infectivity of Chlamydia trachomatis elementary bodies, in vitro study
Lactobacillus species dominate the vaginal microbiota of healthy reproductive-age women and protect the genitourinary tract from the attack of several infectious agents. Chlamydia trachomatis, a leading cause of sexually transmitted disease worldwide, can induce severe sequelae, i.e. pelvic inflammatory disease, infertility and ectopic pregnancy. In the present study we investigated the interfe...
متن کاملChlamydia trachomatis elementary bodies possess proteins which bind to eucaryotic cell membranes.
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...
متن کاملClass specific immunoglobulin response to individual polypeptides of Chlamydia trachomatis, elementary bodies, and reticulate bodies in patients with chlamydial infection.
Sera from 10 women with Chlamydia trachomatis culture positive cervicitis and sera from six men with C trachomatis positive non-gonococcal urethritis were studied for the presence of IgG, IgM, and IgA antibodies to polypeptides of C trachomatis elementary bodies and reticulate bodies using immunoblotting techniques. All the sera with IgG, IgM, or IgA immunoglobulins specific to C trachomatis re...
