What is the primary mode of transmission for Toxoplasma gondii?

• A. Inhalation of spores
• B. Contact with infected human blood
• C. Ingestion of soil contaminated with cat feces
• D. Sexual contact with infected individuals

Answer: (C)

The primary mode of transmission for Toxoplasma gondii is through the ingestion of oocysts shed in the feces of infected cats. When cats defecate, they can contaminate soil, water, or food with these oocysts. Individuals can become infected if they accidentally ingest contaminated soil, water, or undercooked meats from infected animals. This route of transmission is particularly significant because it highlights the role of cats in the life cycle of Toxoplasma gondii, making the environment a critical factor in the spread of this parasite. Other options do not accurately represent the primary transmission method for Toxoplasma gondii. For instance, inhalation of spores and contact with infected human blood are not recognized as key pathways for this particular parasite's transmission. Similarly, sexual contact is not associated with the spread of Toxoplasma, as it primarily transmits through the fecal-oral route or consumption of contaminated food or water.
