TRICHOMONAS
Trichomonas
is caused by a single-cell parasite, Trichomonas vaginalis.
First discovered in 1836, it has proven to be quite a common
sexually transmitted disease. It is found in 50% -
75% of prostitutes and 5% - 15% of women seen in gynecology
clinics. Since the parasite rarely causes symptoms
in men, reinfection of women by their untreated partners
is common.
Common
Signs & Symptoms
Trichomonas infection frequently has no symptoms.
In women with symptoms, the usual presentation consists
of a yellowish-green frothy vaginal discharge (pictured)
that may have a musty odor. Vaginal itchiness is also
common. Other symptoms may include lower abdominal
pain, pain with urination, and pain during intercourse (dyspareunia).
Symptoms often worsen around menstruation (one's period).
The vagina
and cervix
can be swollen and irritated ("strawberry cervix").
How's
it Diagnosed?
Diagnosis is made by examining the vaginal discharge under
a microscope. Trichomonas is a pear-shaped protozoa
with a tail (flagellate). This picture is a view of
an infected cervix and vaginal discharge as seen through
the speculum.
How's
it Treated?
Even
though this infection is not a bacteria, it can be cured
with the an antibiotic. The cure rate is 95%, but
the sexual partner also needs treatment at the same time
to prevent re-exposure and reinfection. The antibiotic
used, metronidazole (Flagyl) causes nausea and vomiting
if taken with alcohol.
How
do I avoid Getting It (Prevention)?
Abstinence or consistent and correct condom
use will prevent transmission of this parasite from
one person to the next.
