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).
