Viral gene sequence length comparison of completely sequenced aMPV and hMPV. A comparison of S-01, Colorado (aMPV-Ca), AY590688, Goose(aMPV-Ca)/DQ009484, PL-1(aMPV-Cb)/EF199771, USA (aMPV-Cb)/AY579780, Human001(hMPV) /AF371337, GZ01(hMPV)/GQ153651, VC03 (aMPV-B)/AB548428 and LAH A (aMPV-A/AY640317 was accomplished. Variation in size of the G, L, SH, N, F and M2 genes was indicated. The length of intergenic regions between the major functional genes were included; nt, Nucleotides. The different regions between the genomic structures are shown in red marks and shaded areas.
