Infection of Hysterectomized Mice with Chlamydia muridarum and Chlamydia trachomatis

Stimulation of the cytosolic receptor for peptidoglycan, Nod1, by infection with Chlamydia trachomatis or Chlamydia muridarum.

Infection of epithelial cells by the intracellular pathogen, Chlamydia trachomatis, leads to activation of NF-kappaB and secretion of pro-inflammatory cytokines. We find that overexpression of a dominant-negative Nod1 or depletion of Nod1 by RNA interference inhibits partially the activation of NF-kappaB during chlamydial infection in vitro, suggesting that Nod1 can detect the presence of Chlam...

Bioluminescence Imaging of Chlamydia muridarum Ascending Infection in Mice

Chlamydial pathogenicity in the upper genital tract relies on chlamydial ascending from the lower genital tract. To monitor chlamydial ascension, we engineered a luciferase-expressing C. muridarum. In cells infected with the luciferase-expressing C. muridarum, luciferase gene expression and enzymatic activity (measured as bioluminescence intensity) correlated well along the infection course, su...

Infection Modulates Chlamydia trachomatis

P-59: Chlamydia Trachomatis Infection in Femaleswith Secondary Infertility

Background: We designed a prospective study to assess the role of Chlamydia in secondary infertility Materials and Methods: 40 women with secondary infertility and 30 term healthy pregnant women of similar age composition were studied for past and present chlamydia trachomatis infection. Women attending the outpatient department of Obstetrics and Gynaecology with complaint of secondary infertil...

The genetic basis of plasmid tropism between Chlamydia trachomatis and Chlamydia muridarum

The development of genetic transformation technology for Chlamydia trachomatis using its endogenous plasmid has recently been described. Chlamydia muridarum cannot be transformed by the C. trachomatis plasmid, indicating a barrier between chlamydial species. To determine which regions of the plasmid conferred the species specificity, we used the novel approach of transforming wild-type C. murid...
