Interaction of Herpes Simplex Virus (HSV) glycoprotein D (gD) with the host cell surface during Chlamydia trachomatis/HSV co-infection stimulates chlamydiae to become persistent.
For approach 2, specimens initially positive by SDA and the Hybrid Capture 2 CT-ID DNA Test (HC2; Digene Corp.) were retested by different NAATs (SDA, PCR, AC2, and the APTIMA assay for C. trachomatis [ACT]).
Aliquots of the urine samples were sent to Aarhus, Denmark, and further examined with the Roche COBAS Amplicor CT (RCA) PCR, the Gen-Probe Aptima Combo 2 assay (AC2) targeting the C. trachomatis 23S rRNA, and the Aptima C. trachomatis assay (ACT) targeting the 16S rRNA molecule.
Members of the conserved TarP protein family comprise such effector proteins that polymerize actin, and in the case of the C. trachomatis TarP protein, has been shown to play a critical role in pathogenesis.
We examined the effects of domain specific Tarp mutations on chlamydial invasion and growth and demonstrate that C. trachomatis clones harboring engineered Tarp mutants lacking either the actin binding domain or the phosphorylation domain had reduced levels of invasion into host cells.

In an analytical-method comparison study of clinical samples, the Abbott RealTime CT new formulation assay (m2000 real-time PCR), consisting of a duplex PCR targeting different parts of the cryptic plasmid in Chlamydia trachomatis, was compared both with version 2 of the Roche Cobas TaqMan CT assay, comprising a duplex PCR for a target in the cryptic plasmid and the omp1 gene, and with the Gen-Probe Aptima Combo 2 assay (AC2) targeting the C. trachomatis 23S rRNA molecule.
These data indicate that CT694 is a novel T3S-dependent substrate unique to C. trachomatis, and that its interaction with host proteins such as AHNAK may be important for aspects of invasion or development particular to this species.
IL-8 induced by infection with C. trachomatis L2 was shown to be dependent on ERK and independent of p38 and Jun N-terminal MAPK by use of chemical inhibitors of the signaling pathways.

To determine the ability of polymorphic membrane proteins (Pmps) to induce cross-species protective immune responses, recombinant fragments from all nine C. trachomatis serovar E Pmps were used to vaccinate BALB/c mice utilizing CpG-1826 and Montanide ISA 720 as adjuvants.
In this chapter, we outline two proximity labeling systems to circumvent these issues to study (1) eukaryotic proteins that localize to the membrane-bound inclusion formed by Chlamydia trachomatis using BioID, and (2) chlamydial proteins that are inserted into the inclusion membrane using APEX2.
Determination of APOE genotype showed that patients PCR-negative in all assays, and those positive in the C. trachomatis - and pan-bacteria- (excluding Chlamydia) directed assays, had distributions of the APOE epsilon2, epsilon3 and epsilon4 alleles mirroring those of the general population (i.e. about 8%, 79% and 13%, respectively).
These results demonstrate that AMP CT is highly sensitive for the detection of C. trachomatis in endocervical specimens and in urine specimens from men and women.
We compared the Gen-Probe transcription-mediated amplification assay (AMP CT), the Abbott LCx assay, and the Roche COBAS AMPLICOR assay for the detection of Chlamydia trachomatis in a mixed population in urine samples.
The AMP CT is a sensitive and specific nucleic acid hybridization assay for the detection of C. trachomatis in endocervical swab specimens from women, urethral swab specimens from men, and urine specimens from men and women.
