By use of a transient replication assay, nine genes involved in DNA replication were identified in the genome of the Autographa californica baculovirus. Six genes encoding helicase, DNA polymerase, IE-1, LEF-1, LEF-2, and LEF-3 are essential for DNA replication while three genes encoding P35, IE-2, and PE38 stimulate DNA replication. No stimulation by the AcMNPV pcna gene, encoding a protein with sequence homology to proliferating-cell nuclear antigen, was observed. A pattern of amino acids found in a number of single-stranded-DNA-binding proteins was identified in the carboxyl-terminal region of IE-1.

Avipoxvirus (APV) infections have been observed in a wide variety of wild, captive and domestic avian hosts, recently including a range of island endemic and endangered species. However, not enough is known about genome diversity and phylogenetic relationships of APVs, as well as their host-range specificity. A wild stone curlew (Burhinus oedicnemus) was recovered in Sardinia (Italy), showing large wart-like lesions and nodules on both legs and toes, which resulted positive to poxvirus by PCR. Histopathological examination of the lesions showed ballooning degeneration and large intracytoplasmic inclusion bodies consistent with APV infection. A multiple gene sequencing approach was applied to highlight the phylogenetic relationships of this virus with a panel of selected APVs at the clade and subclade levels. This novel isolate was characterized by sequencing partial 4b core protein, P35 (locus fpv140) and DNA polymerase genes and phylogenetic analyses assigned it to clade A, (Fowlpox virus, FWPV), subclade A2. Conservation implications of avian pox presence in Sardinian stone curlews and possibly in other island bird species are discussed.

Poxvirus infections have been reported in domestic, captive, and wild avian hosts including many raptor species. A wild Common Buzzard ( Buteo buteo) admitted to a wildlife veterinary clinic in Sardinia, Italy, showed multiple, wart-like proliferative cutaneous lesions on both legs. Histologically, there was ballooning degeneration and large intracytoplasmic inclusion bodies consistent with avipoxvirus (APV) infection. Diagnosis was confirmed by PCR detecting APV genes: P4b (locus fpv167), P35 (locus fpv140), and partial DNA polymerase. Phylogenetic analyses were performed to compare the detected virus with a panel of selected APVs. Analyses of P4b and DNA polymerase assigned the virus to clade A (fowlpox virus), subclade A7, grouping with many other APVs previously isolated in birds of prey. Further research should highlight the diversity of avian pox viral strains circulating among Common Buzzards as well as the phylogenetic role of locus fpv140 (P35) in comparison with the more-conserved P4b and DNA polymerase genes.
