Abstract

A virus with picorna-like biophysical properties was isolated from South African honey bees. On the basis of serology, it was identified as an isolate of black queen-cell virus (BQCV). Nucleotide sequence analysis revealed an 8550 nt polyadenylated genome containing two large ORFs. The 5′-proximal ORF (ORF 1) represented 4968 nt while the 3′-proximal ORF (ORF 2) represented 2562 nt. The ORFs were separated by a 208 nt intergenic region and were flanked by a 657 nt 5′-untranslated region and a 155 nt 3′-untranslated region. Deduced amino acid sequences for ORF 1 and ORF 2 were most similar to the non-structural and structural proteins, respectively, of C virus (DCV), virus (RhPV), Himetobi P virus (HiPV) and intestine virus (PSIV). It is proposed that BQCV belongs to the group of picorna-like, insect-infecting RNA viruses constituted by DCV, RhPV, HiPV and PSIV.
