What habitat is most associated with Toxoplasma gondii?

Toxoplasma gondii is primarily associated with soil and vegetation because the organism's oocysts, which are the infectious stage of the parasite, are shed in the feces of infected cats. These oocysts can survive in the environment, particularly in soil and in vegetation, for long periods. When animals, including humans, come into contact with contaminated soil or consume raw or undercooked vegetables that have been exposed to contaminated soil, they can become infected.

This is particularly significant in understanding how the parasite is transmitted and the environments where the risk of infection is highest. The presence of oocysts in the environment is a critical aspect of the lifecycle of Toxoplasma gondii, making habitats like soil and vegetation essential for its propagation and transmission.
