Transmission
There are several routes of transmission but the oral route is the major source of infection, so it’s results from either ingestion or handling of undercooked or raw meat (mainly lamb and pork) containing tissue cysts (bradyzoites) or water or food containing oocysts excreted in the feces of infected cats (2). Transmission of Toxoplasma gondii by organ transplantation from a seropositive donor to a seronegative recipient is a potential cause of human being infection (1). Toxoplasma gondii can also be transmitted via blood, thus laboratory personnel are under a great danger by contact contaminated needles (2). In some cases, the specific route of transmission is not clearly defined. Transmission during breastfeeding or direct human-to-human transmission other than vertical-transplacentally (mother to fetus) has not been recorded (1, 2).
