trichinosis
A disease that is due to eating raw or
undercooked pork or wild game that is infected with
Trichinella spiralis larvae. Initial symptoms are
abdominal discomfort, nausea, diarrhea, vomiting,
fatigue, and fever. Next usually come headaches,
fevers, chills, cough, eye swelling, aching joints,
muscle pains, itchy skin, diarrhea, and constipation.
With heavy infection, patients may experience diffi-
culty coordinating movements and have heart and
breathing problems. In severe cases, death can
occur. The severity of symptoms depends on the
number of infectious worms consumed in meat. To
avoid trichinosis, pork and wild game meat should
be thoroughly cooked (freezing wild game may not
effectively kill all worms); all meat that is fed to pigs
or other wild animals should be cooked first; meat
grinders should be cleaned thoroughly; curing (salt-
ing), drying, smoking, and microwaving meat do not
consistently kill infective worms. Irradiation of wild
game meat can kill the parasites. A person who
thinks he or she has trichinosis should seek medical
attention. Also known as trichinellosis.
trichobezoar
A wad of swallowed hair and food.
Trichobezoars can sometimes cause blockage of the
digestive system, especially at the exit of the stom-
ach. See also 
bezoar.
trichomonas
A single-celled protozoan parasite
best known in medicine because one species causes
vaginitis (vaginal inflammation). The species of tri-
chomonas responsible for the sexually transmitted
disease is Trichomonas vaginalis. The vagina is the
most common site of infection in women, and the
urethra (urine canal) is the most common site of
infection in men. See also 
trichomoniasis.
trichomoniasis
Infection with the parasite
Trichomonas vaginalis. The infection is sexually
transmitted, and the vagina is the most common site
of infection in women, while the urethra (urine
canal) is the most common site of infection in men.
Most men with trichomoniasis have no signs or
symptoms; however, some men may have an irrita-
tion inside the penis, mild discharge, or slight burn-
ing after urination or ejaculation. Many women have
signs or symptoms of infection which include a
frothy, yellow-green vaginal discharge with a strong
odor. The infection may also cause discomfort dur-
ing intercourse and urination, as well as irritation
and itching of the female genital area. Treatment is
usually with the drug metronidazole given by mouth
in a single dose. Having trichomoniasis once does
not protect a person from getting it again.
