The purified product was sequenced on 1/8 th of a pico titre plate using the 454 technology by Roche at Inqaba Biotech (South Africa). The sequences were analysed through quality check and removal of very short sequences before being assembled using CLC genomic workbench v4.6 (http://www.clcbio.com/index.php). Blastn and blastx searches were performed through the Camera 2.0 portal [26, 27] and searches through NCBI (http://www.ncbi.nlm.nih.gov/blast/Blast.cgi). The viral blast hits with an e-value of 10 -4 or lower were further analysed.
