This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.Toxoplasma gondii (T. gondii), strain Dubey, was originally isolated from a pig heart obtained on a farm in Massachusetts, USA, and passed singly through a cat in 2002. The collected oocysts were maintained in refrigeration until 2006, at which time fresh oocysts were produced by passage through a mouse and cat. The deposited tachyzoites are from the third-generation of monoxenously-produced oocysts passaged through kittens and isolated in cell culture.T. gondii, strain Dubey was deposited to BEI Resources as a unique strain that has demonstrated serial cat-to-cat transmission.Each vial of NR-43998 contains approximately 0.5 mL of culture in cryopreservative.
