The temporal appearance of 4 viral proteins was detected in bluetongue virus (BTV)-infected Vero cells by indirect immunofluorescence staining with monoclonal antibodies (MAb) to BTV structural proteins VP2 and VP7 and nonstructural proteins NS1 and NS2. Bluetongue viral proteins were detected at distinct intervals after inoculation of Vero cells; VP7 was first detected 3 hours after inoculation, NS1 and NS2 at 5 hours after inoculation, whereas VP2 was not detected until 8 hours after inoculation. Patterns of fluorescence varied with the fixative used, but each MAb induced a distinct pattern of fluorescence in infected cells. Flow cytometry, which was used with each of the 4 MAb, proved to be an accurate and sensitive method of detecting BTV-infected P3 mouse myeloma cells. The temporal appearance of each viral protein in BTV-infected P3 cells was similar to that detected in BTV-infected Vero cells. Advantages of flow cytometry over conventional immunofluorescence staining to detect BTV-infected cells included: (1) enumeration of the proportion of infected cells in a population; (2) further characterization of infected cells, including estimates of their viability; and (3) computer-assisted storage and analysis of data obtained.
