Toxoplasmosis is caused by the obligate intracellular sporozoan,Toxoplasma gondii. It can be acquired through ingestion of undercooked meats, or through handling and inhalation of household cat feces. The infectious agent crosses the blood brain barrier of the neonate and deposits within the brain and retina of the eye (since the retina is an extension of neurological tissue). Some possible risk factors include: concurrent HIV infection, immunosuppression (particularly of T cell lines), and congenital infections. The later the exposure and infection of t. gondii, the higher the risk of transmission is to the developing baby. Some warning signs to keep in mind are: history of exposure to undercooked meats or cat feces, and maternal symptoms of significant and sudden headache, seizures, or gait disturbances. In about 21% of neonates, toxoplasmosis can result in serious life threatening conditions, such as impaired cognition or vision. Please consult a medical doctor for appropriate diagnosis and treatment.
