Virulent Newcastle Disease Viruses Circulating in Ethiopia
↓ cleavage residues indicate that the NDV isolates correspond to mesogenic/velogenic pathotypes. Figure 2 Deduced amino acid sequence alignment of F gene sequences of NDV strains isolated from Ethiopia. Names of strains are shown on the left-hand side of the figure. Identification with the reference La Sota (genotype II) vaccine strains is indicated by dots. They indicate the cleavage site of the deduced aa sequence of the F gene. X indicates an ambiguous aa sequence. Abbreviations: Eth, Ethiopia; Chk, chicken. Genetic Distance The Ethiopian NDV isolates have a within-group genetic distance...
