Ibv genotypes and clusters
Webb19 nov. 2024 · Recently, Valastro et al. [ 18] defined IBV strains into six genotypes comprising 32 distinct viral lineages that include several unassigned recombinants of inter-lineage origin based on the complete S1 gene sequence. The distribution and diversity of these IBV lineages differ with geographic location [ 18 ].
