ASFV does not induce neutralizing antibodies and, for that reason, no serotypic classification scheme has been devised.
However, 22 ASFV genotypes have been identified using a genotyping strategy based on partial nucleotide sequencing of the p72 gene (Boshoff et al. 2007).
Subtyping is based on full-length sequencing of the p54 gene.
Further discrimination among isolates can be done by analysis of the CVR within the B602L gene (Gallardo et al. 2009).
