Myxoma virus (MV), a member of the family Poxviridae, is the causative agent of myxomatosis, a fatal disease of the European rabbit. The MV genome is a linear, double-stranded DNA molecule that encodes several factors important for evasion of the host immune system. Sequencing the right-end region of the MV genome identified an 801 bp open reading frame(More)
Recently, myxoma virus was shown to encode an additional member of the serpin superfamily. The viral gene, called serp2, was cloned, and the Serp2 protein was shown to specifically bind to interleukin-1beta (IL-1beta)-converting enzyme (ICE), thus inhibiting the cleavage of pro-IL-1beta by the protease (F. Petit, S. Bertagnoli, J. Gelfi, F. Fassy, C.(More)

Myxomatosis in Europe is the result of the release of a South America strain of myxoma virus in 1952. Several attenuated strains with origins in South America or California have since been used as vaccines in the rabbit industry. We sequenced the genome of the SG33 myxoma virus vaccine strain and compared it with those of other myxoma virus strains. We show(More)
An enzyme-linked immunosorbent assay (ELISA) was developed and compared with 2 reference diagnostic tests (indirect immunofluorescence [IF] and complement fixation) to detect myxoma virus-specific antibodies in sera from 50 rabbits experimentally vaccinated with an attenuated strain of myxoma virus or with a Shope fibroma virus. The ELISA was highly(More)
An efficient procedure of a protein isolate production from the evening primrose cake was developed. The cake is a by-product of oil extraction from seeds by using the cold pressing method. The evening primrose cake contains 22.7% of protein. Its content in the protein isolate derived from the cake is 74%. Proteins present in evening primrose seeds are rich(More)
African swine fever virus was detected in various samples using a molecular hybridization technique. A fragment located in a constant area of the viral genome was biotin-labelled. This probe, when present at a concentration of 100 ng/ml of the hybridization solution, could detect 10 pg of target DNA immobilized on nitrocellulose with cellular DNA and RNA.(More)
