crescent shaped with a pointed anterior (conoidal)
end and a rounded posterior end

first described in 1908 by Nicolle and Manceaux in a
small North American rodent called gundi
Toxoplasmosis

mononucleosis syndrome with prolonged
fever, lymphadenopathy, elevated liver
enzymes, lymphocytosis, and weakness


chorioretinitis
eye disease, learning disabilities

Consuming undercooked, contaminated meat
5–23 days.


Eating food that is prepared by contaminated
kitchen equipment that have had contact with
raw, contaminated meat
Drinking water contaminated with
Toxoplasma gondii
Mother-to-child (congenital) transmission.
Receiving contaminated blood transfusions or
organ transplants (Rare)
ingesting the parasite unintentionally after
coming into contact with cat feces that carry
Toxoplasma gondii

DIAGNOSIS
• Tests for detecting IgG antibody include:
Enzyme-linked immunosorbent assay (ELISA)
Sabin-Feldman dye test
Indirect fluorescent antibody test (!FAT)
Latex agglutination test
Magnetic resonance imaging (MRl) and computed
tomography (CT)
Polymerase chain reaction (PCR)

PREVENTION
Pyrimethamine and sulfadiazine (add folinic acid in
an immunosuppressed host)
Spiramycin

Rinse fresh fruits and vegetables under
running water.
Use a food thermometer to ensure foods are
cooked to a safe internal temperature
Wear gloves when gardening and during any
contact with soil or sand because it might be
contaminated with cat feces that contain
Toxoplasma. Wash hands with soap and
water after gardening or contact with soil or
sand.
Wash your utensils, cutting boards, and
countertops with hot, soapy water after
preparing each food item
Wash hands with soap and water after
cleaning out a cat’s litter box.
Teach children the importance of washing
hands to prevent infection.
