Characterization of the complete genomes of Camelus dromedarius papillomavirus types 1 and 2

Summary, in English

Camel papillomatosis has been described previously, but the genome of the suspected papillomavirus (PV) has not been identified. An outbreak of papillomatosis occurred in a dromedary farm of 55 animals in Sudan during August 2009. The disease was only present in young animals aged about 3-7 months, of which 44% (11/25) were affected with lesions, mainly on the lips and lower jaw. This study reports for the first time the complete genomes of Camelus dromedarius papillomavirus types 1 (CdPV1) and 2 (CdPV2), isolated from a cauliflower-like nodule and a round oval raised nodule, respectively. Pairwise comparisons of their L1 nucleotide sequences revealed 69.2% identity, and phylogenetic analyses suggested that these two PV types are grouped within the genus Deltapapillomavirus. Both viruses were isolated from fibropapillomas, although no putative E5 proteins homologous to that of bovine papillomavirus type 1 were identified. The genetic information will be useful for evolutionary studies of the family Papillomaviridae, as well as for the development of diagnostic methods for surveillance of the disease in dromedaries.
