Trichomonas vulvovaginitis

Trichomonas vulvovaginitis is a very common sexually transmitted infection of the female genitalia. The causal agent is the protozoan Trichomonas vaginalis, living in a humid environment.

Clinical Image
In women, the vagina and urethra are the most affected. It manifests in a foamy, yellowish-green vaginal discharge. The illness is associated with unpleasant odour, burning, dysuria, swollen labia, dyspareunia and the finding of small red dots - haemorrhages on cervix. Men are usually vectors, infection is often asymptomatic or with signs of urethritis.

Diagnosis
It is carried out microscopically in a native preparation or culture. The sample is taken from cervix, fornix vaginae, urethra, and urine. There may also be used direct immunofluorescence and ELISA.

Differential Diagnosis
We need to distinguish other vaginal inflammation.

Therapy
Metronidazole 2&thinsp;×&thinsp;500 mg/day for 7 days or 2 g as a single dose.

Progress and Prognosis
In women, treatment with antibiotics is necessary; in men, it usually disappear spontaneously.
