==Life Cycle==

The life cycle of ''T. gondii'' is cmplex, usually indirect and often referred to as '''facultatively heteroxenous'''. Intermediate host is not essential for completion of the life cycle. Gametogony (sexual stage) is host specific for felids.

If a pregnant queen or human is naive to ''Toxoplasma gondii'' at the time of ingestion, '''transplacental infection''' can occur. The outcome of this depends on the stage of gestation. Infection during the first trimester usually has severe consequences, such as stillbirth or abortion; infections during the second or third trimesters are more likely to give rise to an infected foetus.
