FIG. 2.
RT-PCR analysis of rabies virus genomic RNA in brain tissue from mice infected i.n. with CVS-F3. Brains from two mice of each of the indicated strains were collected at 8, 13, 21, and 37 days after i.n. infection with CVS-F3, and RNA was extracted and subjected to RT-PCR analysis for rabies virus genomic RNA (RV) as described in Materials and Methods. Amplification of G3PDH mRNA served as an internal control.
