Abstract
A diagnostic assay for detecting a negative-strand RNA virus in a sample and a genetically engineered cell for use in the assay are disclosed. The cell expresses a heterologous DNA-dependent RNA polymerase that synthesizes a minigenome or miniantigenome of the RNA virus from a cDNA template present in the cell. The cell also expresses the nucleocapsid proteins of the negative-strand virus that are necessary for replication of the minigenome or miniantigenome. Infection of the cell by the negative-strand virus results in expression of a reporter gene product encoded by the miniantigenome.
