We present an analysis of the complete genome of African swine fever virus (ASFV) strain BA71V, including 80 kbp of novel sequence and 90 kbp previously reported by several authors. The viral DNA is 170,101 nucleotides long and contains 151 open reading frames. Structural and/or functional information is available on 113 viral proteins. ASFV encodes five(More)
Certain viruses have evolved mechanisms to counteract innate immunity, a host response in which nuclear factor kappaB (NF-kappaB) transcription factors play a central role. African swine fever virus encodes a protein of 28.2 kDa containing ankyrin repeats similar to those of cellular IkappaB proteins, which are inhibitors of NF-kappaB. Transfection of the(More)
A haemadsorption microtest for African swine fever (ASF) virus is described. This assay is as sensitive and its response is faster than the conventional assay which uses buffy coat cultures in Leighton tubes. The method can also process a larger number of samples by using smaller amounts of swine blood and laboratory space. A plaque assay for ASF virus(More)
The open reading frame EP153R, located within the EcoRI E' fragment of the African swine fever (ASF) virus genome, is predicted to encode a membrane protein of 153 amino acids that presents significant homology to the N-terminal region of several CD44 molecules. EP153R contains multiple putative sites for N-glycosylation, phosphorylation, and(More)
During the cytoplasmic maturation of African swine fever virus (ASFV) within the viral factories, the DNA-containing core becomes wrapped by two shells, an inner lipid envelope and an outer icosahedral capsid. We have previously shown that the inner envelope is derived from precursor membrane-like structures on which the capsid layer is progressively(More)
The broncho-alveolar lavage of a pig (20-40 kg) contains about 1.6 x 10(9) alveolar cells, half of which were macrophages. The number of cells in the lavage of bacille Calmette Guerin (BCG)-treated pigs increased about 4-fold. Both African swine fever virus-infected porcine alveolar macrophages and blood monocytes produced about 1000 hemadsorption(More)
The gene encoding protein p72, the major structural protein of African swine fever virus and one of the most immunogenic proteins in natural infection has been mapped and sequenced. The gene was mapped by using oligonucleotide probes deduced from amino acid sequences of tryptic peptides obtained from purified protein p72. This allowed the location of the(More)
