Mycoplasma genitalium

What is Mycoplasma genitalium (MG)

MG is a bacterium that has been recently identified as a sexually transmitted infection.  It can infect the mucus membranes of the urethra, cervix, throat, and anus.

It is transmitted via vaginal, anal, and oral sex.

What are the symptoms?

  • MG infection can be silent (no symptoms) or can present with:
  • Males
  • Penile discharge
  • Stinging or burning on passing urine
  • Females
  • Pain in the pelvis and during sexual intercourse
  • Abnormal vaginal discharge

How is MG tested for?

MG is tested for on a swab or urine in the same way as the laboratory tests for chlamydia infection

How is MG treated?

MG is treated with antibiotics.  Unfortunately antibiotic resistance is a problem and you may need to have a second course if the first one doesn’t clear the infection

How do I know if the infection is gone?

You will be tested again 3-4 weeks after antibiotic treatment.  If the test is still positive, you will be prescribed a different antibiotic.

Should my partner/s be treated?

Yes, it is important to tell all sexual partners from the past three months of your diagnosis and suggest they have testing and treatment.  You must use condoms during sex for a week after antibiotic treatment.

How do I avoid getting MG infection again?

The best protection is to use condoms with all sexual activity – i.e. practice safe sex.  More information can be found here – https://www.ashs.org.nz/safer-sex.html.
