What is Toxoplasmosis commonly associated with?

Toxoplasmosis is primarily a parasitic infection caused by the protozoan Toxoplasma gondii. This organism is commonly found in cat feces as cats are the definitive host for the parasite. Humans can become infected through several means, including accidental ingestion of oocysts from cat litter, soil, or contaminated food, particularly undercooked meat. Therefore, association with animal pets, particularly cats, is a significant risk factor for acquiring toxoplasmosis.

The other options do not have a direct connection to toxoplasmosis. Increased sugar intake, old age, and low protein diets do not contribute to the transmission or risk of infection with Toxoplasma gondii, making the association with animal pets the most relevant and accurate choice.
