Nosocomial Buffalopoxvirus Infection, Karachi, Pakistan
Figure 2. Maximum likelihood phylogenetic tree based on a 955-nt alignment of the Karachi isolate and 33 orthopoxvirus sequences of the B5R gene from GenBank constructed with ClustalW (www.ebi.ac.uk/clustalw/index.html) and TREE-PUZZLE (http://bioweb.pasteur.fr/seqanal/interfaces/puzzle.html); figures at nodes represent PUZZLE support values. The orthopoxvirus types are indicated to the right. The Karachi isolate sequence (Pakistan 2005) groups within the buffalopox B5R genes.
