Sensitivity of JUNV to IFN pretreatment.

<p>Vero cells were treated with IFN-α, β or γ at the indicated concentrations for 8 h and then infected with Romero JUNV (A) or Candid#1 JUNV (B) at an MOI of 0.1. At 2 days p.i., supernatants were collected and assayed for virus production by plaque assay. Due to the severe cytotoxicity caused by IFN-γ treatment at 2000 U/ml, virus infection was not performed at this condition. Data represent the average of three replicates ±SEM.
