Abstract

The ttansmission of T. gondii is related with raw meat (Frenkel 1973) or oocyst ingestion. Oocysts are shed by cats (Jewell et al. 1972) and in the soil they are extremely resistant to environmental conditions (Frenkel el al. 1975). Oocys t infection occurs by fecal oral oontamination and may involve transport hosts such as house flies (Wallace 1971) or cockroaches (Wallace 1972).
