Fig. 4
Multiple protein sequence alignments showing the differences in P1 and ORF6 between type 1 and type 2 strains. a The large region of variation in P1. Type1 is representative sequence for all type 1 strains and type2 is representative of all type 2 strains. b The large region of variation in ORF6. Type1 is representative of all type 1 strains, except M129, which is also shown (differences in M129 highlighted in red). Type2 is representative of all type 2 strains except for MAC, which is also shown (differences in MAC highlighted in red)
