Answer:
a. granuloma formation
Explanation:
Toxoplasmosis is an infection caused by a protozoan called “Toxoplasma Gondii,” found in the feces of cats and other felines, which can be found in humans and other animals. It is caused by eating contaminated water or food and is one of the most common zoonoses (animal-borne diseases) in the world. Usually toxoplasmosis is accompanied by the formation of granuloma that triggers an inflammatory process. Granuloma is responsible for isolating the offending agent and is therefore a useful defense mechanism. However, the formation of this structure does not always result in the elimination of the causative agent, which may commonly be resistant to destruction or degradation.
