Mycoplasma Genitalium Infection
Essentials
- Sexually transmitted
- The bacterium Mycoplasma genitalium has been known for long, but its significance as a pathogen has been confirmed over the recent years.
- Must be considered in the differential diagnosis of urethritis and cervicitis where the aetiology of symptoms is unclear after chlamydia Chlamydial Urethritis and Cervicitis and gonorrhoea Gonorrhoea have been excluded.
- Asymptomatic people should not be screened.
- Encountered in about 5% of patients attending sexually transmitted diseases clinics in the Nordic countries.
Aetiology and clinical picture
- Mycoplasma genitalium is the smallest known bacteria.
- Clinical picture resembles that of Chlamydia infection.
- Asymptomatic infections are common.
- Mycoplasma causes urethritis in men, cervicitis in women, and it may also cause pelvic inflammatory disease Pelvic Inflammatory Disease (Pid).
Diagnosis
- Detection of the nucleic acid from a mucous membrane or first-void urine sample http://www.dynamed.com/condition/mycoplasma-and-ureaplasma-genito-urinary-infections#MOLECULAR_TESTING
- If there is suspicion of a strain resistant to azithromycin, antimicrobial sensitivity testing may be additionally performed.
- The sample is recommended to be taken only in symptomatic patients when tests for chlamydial and gonococcal infections as well as clean-voided urine have proven negative.
- particularly of men with unclear urethritis (urethral discharge and burning on urination)
- of women with lower abdominal pain, burning on urination and increased leucorrhoea
- if a permanent sexual partner has been diagnosed with Mycoplasma genitalium infection.
