Tricky

This is a Giemsa-stain from a woman complaining of pain on urination and frequency of urination. She also notes a purulent malodorous thin vaginal discharge and itching. She is sexually active but her male partner is asymptomatic. Physical exam shows erythema of the vulva and vaginal mucosa with green frothy discharge and punctate hemorrhages on the vagina and cervix.

Challenge: What's the organism?

This is Trichomonas vaginalis, a flagellated protozoan.
