  • You should not have oral, anal or vaginal sex during your course of chlamydia treatment or for seven days after a single dose of chlamydia treatment and also until your current partner completes their treatment and until both you and your partners symptoms have abated. (chlamydiaexplained.com)
  • METHODS: We used RNA-bait enrichment and whole-genome sequencing to compare rectal, vaginal and endocervical samples collected at the same time from 26 study participants who attended Fijian Ministry of Health and Medical Services clinics and tested positive for C. trachomatis at each anatomic site.

  • If youre pregnant, untreated chlamydia can be transmitted to the baby during vaginal delivery. (chlamydiaexplained.com)
  • Examples of enzymes that ilomastat inhibit include rabbit MMP9, thermolysin, peptide deformylase, and anthrax lethal factor endopeptidase (LF) produced by the bacterium Bacillus anthracis. (wikipedia.org)
  • We report that chlamydiae, which are obligate intracellular bacterial pathogens, can inhibit interferon (IFN)-γ-inducible major histocompatibility complex (MHC) class II expression. (silverchair.com)
  • To escape CD4 + T cell recognition, pathogens may need to inhibit the IFN-γ-inducible MHC class II expression. (silverchair.com)
  • The classification of bacteria , including the archaea, into phyla is somewhat less established due to the complexities of bacterial diversity and the ongoing refinement of bacterial taxonomy . (microbiologynote.com)
  • The overall scientific objective of this project was to increase our fundamental understanding of mechanisms underlying C. trachomatis virulence. (europa.eu)
