Infection by one organism in this genus is detected by PCR of its B1 gene or by the Sabin- Feldman dye test.
Infection by one organism in this genus is detected by PCR of its B1 gene or by the Sabin- Feldman dye test. Infection by one organism in this genus causes irregularly shaped germinal centers and clusters of epithelioid histiocytes on lymph node biopsy. Like sarcocystis, organisms in this genus have a motile tachyzoite stage susceptible to antibiotics and a bradyzoite stage that is resistant. In AIDS patients, either lymphoma or infection by a member of this genus are the main causes of ring-enhancing lesions in the brain. It's not Listeria, but congenital infection with an organism in this genus causes a characteristic chorio-retinitis; that organism in that genus is the first of the TORCH infections, which is why pregnant women are told to avoid raw milk and raw meat. For 10 points, name this genus of parasites, whose gondii species is commonly transmitted from cats to humans.
