Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Isolation
clinical specimen - animal
Nebraska, United States
Isolation date: 1998
Product Format
frozen
Storage Conditions
liquid nitrogen vapor phase
Type Strain
no
Medium
RPMI 1640 medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 4.5 g/L glucose, 10 mM HEPES, and 1.0 mM sodium pyruvate, 95%; horse serum, 5%
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
Subcultivation
