Figure 2

Midpoint rooted maximum likelihood phylogram of filovirus-like nucleoprotein (NP) nucleotide sequences from vespertilionid bats. Three major geographic clades of the genus Myotis are shown by shaded boxes -- the big brown bat (Eptesicus fuscus) sequence has been added for comparison and to show the rooting that divides Old and New World Myotis. Support values (nonparametric bootstrap support/approximate likelihood ratio tests) are given above the branches. GenBank accession numbers or museum voucher numbers are provided in parentheses. See Additional file 8, Table S3 for details of specimen records and acronyms. Red numbers indicate the sum and presumed phylogenetic position of independent observed disruptions to the open reading frame. The scale bar is based on substitutions per site.
