Toxoplasma gondii is characterized by which feature?

Toxoplasma gondii is a protozoan parasite known for its wide-ranging implications in both immunocompetent and immunocompromised individuals. One of its most notable characteristics is the potential for congenital infection if a pregnant woman becomes infected, particularly during the first trimester. This can lead to serious outcomes for the fetus, including neurological damage and other developmental issues. Additionally, people can become infected through the ingestion of oocysts, which are found in cat feces or contaminated food and water.

Furthermore, Toxoplasma gondii is globally distributed, often referred to as having a cosmopolitan distribution. This means it is prevalent in many regions around the world, making it a common concern in various populations. When it comes to serological testing for Toxoplasma infection, interpretation can be challenging due to factors like cross-reactivity with other infections and the presence of different antibody profiles in acute or latent infections.

The combination of these characteristics—possible congenital infection through maternal transmission and the complexities associated with serological testing—highlights the importance of both A and B as features associated with Toxoplasma gondii. Therefore, selecting the option that encompasses both features accurately reflects the significant aspects of this parasite's clinical relevance and diagnostic challenges
