Multiplex STI testing

The project commenced in March of 2006. The main aim of the project was to develop and validate a Multiplex Polymerase Chain Reaction - Reverse Line Blot (mPCR-RLB)assay, which allows the rapid detection of multiple organisms in very low concentrations.

We developed a method using this technology to detect the presence of the following 14 organisms in urine, endocervical and self-collected vaginal swabs.

  • Chlamydia trachomatis
  • Neisseria gonorrhoeae
  • Mycoplasma genitalium
  • Ureaplasma urealyticum
  • Ureaplasma parvum
  • Trichomonas vaginalis
  • Mycoplasma hominis
  • Gardnerella vaginalis
  • Herpes Simplex Virus type 1 and 2
  • adenovirus
  • Neisseria meningitidis
  • Haemophilus influenzae, and
  • Streptococcus pneumoniae.

Urine specimens from males with and without urethritis and urine, endocervial and self-collected swabs from females with and without vaginal symptoms attending sexual health clinics were collected and analysed using the mPCR-RLB method. The detection of the organisms was then linked to demographic, behavioural and clinical data.
