Developmental stage-specific metabolic and transcriptional activity of Chlamydia trachomatis in an axenic medium.
Chlamydia trachomatis is among the most clinically significant human pathogens, yet their obligate intracellular nature places severe restrictions upon research. Chlamydiae undergo a biphasic developmental cycle characterized by an infectious cell type known as an elementary body (EB) and an intracellular replicative form called a reticulate body (RB). EBs have historically been described as me...
متن کاملGenomic transcriptional profiling of the developmental cycle of Chlamydia trachomatis.
Chlamydia trachomatis is one of the most common bacterial pathogens and is the etiological agent of debilitating sexually transmitted and ocular diseases in humans. The organism is an obligate intracellular prokaryote characterized by a highly specialized biphasic developmental cycle. We have performed genomic transcriptional analysis of the chlamydial developmental cycle. This approach has led...
متن کاملQuantifying promoter activity during the developmental cycle of Chlamydia trachomatis
Chlamydia trachomatis is an important human pathogen that undergoes a characteristic development cycle correlating with stage-specific gene expression profiles. Taking advantage of recent developments in the genetic transformation in C. trachomatis, we constructed a versatile green fluorescent protein (GFP) reporter system to study the development-dependent function of C. trachomatis promoters ...
متن کاملChlamydia trachomatis in non-specific urethritis.
Chlamydia trachomatis was isolated from 58.5% of 159 patients with non-specific urethritis (NSU) using irradiated McCoy cell cultures. Patients with persistent Chlamydia-positive NSU remained Chlamydia-positive each time they were examined before treatment and patients with Chlamydia-negative NSU remained Chlamydia-negative during the course of the illness. Neither the duration of symptoms of u...
متن کاملMolecular mechanism of tryptophan-dependent transcriptional regulation in Chlamydia trachomatis.
Tryptophan is an essential amino acid that is required for normal development in Chlamydia species, and tryptophan metabolism has been implicated in chlamydial persistence and tissue tropism. The ability to synthesize tryptophan is not universal among the Chlamydiaceae, but species that have a predicted tryptophan biosynthetic pathway also encode an ortholog of TrpR, a regulator of tryptophan m...
