Figure. Unrooted neighbor-joining tree using the p-distance model (1,000 replicates) for a section of the glycoprotein precursor gene gene, showing bootstrap values of >60 for all sequences identified in this study (283 bp) and indicating site of origin. Captive colony, MF 2004, and BHF 2005 as in Table 1. MF* is from Apodemus sylvaticus, and all other sequences are from Mus musculus. Scale bar indicates number of substitutions per site.
