Trichomoniasis

Trichomoniasis is a sexually transmitted infection caused by trichomonas vaginalis.

Clinical features

It’s asymptomatic in 70%. Foul-smelling, yellow-green coloured vaginal discharge is highly suspicious for trichomoniasis. Other symptoms include:

• Itching
• Burning
• Dyspareunia
• Itchiness
• Redness
• Strawberry cervix – typical appearance of cervix like a strawberry

Diagnosis and evaluation

Physical examination may reveal characteristic appearance or odour.

pH measurement is also important. The pH of the vagina is normally 4 – 4,5, but in case of bacterial vaginosis or trichomoniasis, the pH is > 4,5. The Amine test (for bacterial vaginosis) is positive here as well.

Vaginal smear, the examination of vaginal fluid under the microscope, may also be performed. For trichomoniasis, motile organisms with multiple flagella are visible.

Treatment

Metronidazole is the first line treatment for both the patient and the partner. A single dose 2g p.o. metronidazole may be used.
