cyst,in chronic stage or latent infection when immunity develops .
Oocysts:oval,10x12mm,contains

two sporocysts each containing four sporozoites,and found in stools of infected cats

four months of pregnancy,the fetus may become infected.the baby may

be aborted or does shortly after birth.live infants show signs of congenital toxoplasmosis: hydrocephalus, encephalitis, chorioretinitis and cerebral classification. Maternal antibodies when present(acquired before pregnancy)protect the fetus

Exanthaematous form:typhus fever with

rash and enlarged lyumph nodes
Lymphatic form: enlarged lymph nodes ,liver

Care in handling cats
Avoid contamination of food and drink with cat feces.oocyts in cat feces can remain infective for a long period.
