Key Concepts

Toxoplasmosis

Toxoplasmosis is an infectious disease caused by the parasite Toxoplasma gondii. It can be transmitted to humans through various routes, including ingestion of undercooked meat, contaminated water, or contact with cat feces. Understanding its transmission is crucial, especially regarding its effects on pregnant women and their unborn children.

Vertical Transmission

Vertical transmission refers to the passage of an infectious agent from mother to offspring during pregnancy, childbirth, or breastfeeding. In the case of Toxoplasmosis, the parasite can cross the placenta, potentially leading to serious health issues for the fetus, such as congenital defects or neurological problems.

Placental Barrier

The placental barrier is a selective barrier that separates the maternal blood from the fetal blood, allowing for the exchange of nutrients and waste. However, certain pathogens, including Toxoplasma gondii, can breach this barrier, highlighting the importance of understanding which infections can affect fetal development during pregnancy.
