Comments Derivation by adaptation from the in vivo cultured product ATCC® VR-84™ to Vero cells (ATCC® CCL-81™). The genomic sequences of ATCC® VR-84™ and ATCC® VR-1838™ have not been compared, and ATCC® VR-1838™ has not been tested for infectivity in vivo.
Effect on Host
CPE, Refractile cell rounding
Recommended Host
Vero cells (ATCC® CCL-81™)
Growth Conditions

Temperature: 37°C

Recommendations for Infection: Plate cells 18-24 hours prior to infection and infect when cultures are 75-80% confluent. Remove medium and then wash monolayer with PBS or serum free medium prior to inoculation. Inoculate with a small volume of inoculum (e.g. 1 mL per 25 cm2) diluted to provide an optimal MOI (e.g. 0.1-0.01). Adsorb for 1-2 hours at 37°C in a humidified 5% CO2 atmosphere. End adsorption by adding virus growth medium.

Incubation: 2-4 days at 37°C in a humidified 5% CO2 atmosphere, until CPE is progressed through 80-90% of the monolayer.

Effect on Host
CPE, Refractile cell rounding
