ATCC? Number:PRA-140?
Organism:
Neospora caninum Dubey et al.
Designations: NC-Beef
Isolation: clinical specimen - animal (beef calf (Bos taurus))Nebraska, United States Isolation date: 1998
Depositors: MM McAllister
Biosafety Level:2
Shipped: frozen
Growth Conditions: Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37.0°C Duration: The organism is propagated in Vero cells. Protocol:
-
Scrape the Vero cells into the culture medium when holes develop in the monolayer (tachyzoite clusters are observed in the cells and 7 micrometer long banana-shaped tachyzoites are free in the medium).
-
Transfer approximately 0.5 ml of the harvested medium (or approximately 500,000 tachyzoites) to another T25 flask containing a fresh monolayer of vero cells.
-
Incubate at 37C.
Interval: approximately 1 week
Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material.
