Testing of lateral flow device (LFD) based on animal samples (a) Examples of eye swabs or nasal swabs from uninfected UK sheep tested on the LFD-based assays. (b) Examples of eye swabs or nasal swabs taken from animals with severe bluetongue and tested on the LFD-based assays. (c) Examples of nasal swabs taken from UK goats infected with PPRV. Swabs were taken 4 or 7 dpi as indicated and tested on the LFD-based assays; the remaining eluate from each swab was tested for PPRV genome by real-time PCR, and the result recorded as the Ct determined in the PCR assay.
