73. What the paper actually says. Not as sensational as the reportage.

Felids have been identified as definitive hosts of T gondii, with the parasite multiplying sexually in the cats' gut and spreading oocysts. Humans are infected by ingestion of oocysts spread from feces of infected cats (eg, contaminated sandbox and ingestion of unwashed vegetables), eating undercooked meat infested with T gondii cysts, using knives used to cut infested meat to further cut vegetables, and, occasionally, drinking water from a contaminated water source. The ingestion of the parasite by various intermediate hosts, including humans, leads to the spread of the organism from the intestine to organs, predominantly muscles and the brain. There, under pressure from the immune system, the parasite hides within neurons and glial cells, in cystic structures, with minimal exposure to mediators of the immune system that succeed to contain but cannot eradicate it.

Do you know an estimate of what percent of cats host T gondii?
