Fig 5. Leucocytozoon sub-tree from a Maximum likelihood phylogenetic analysis of haemosporidian sequences constructed from 386 base pairs of the Cytochrome b gene.

Bootstrap values (1,000 replicates) >50 are shown at nodes. Haplotypes derived from Alaska and California duck samples for this study (DUCK16–DUCK48) are shown in bold. Two-letter codes following the lineage names of MalAvi acquired sequences refer to the avian order/s reported as the host origin: Anseriformes (An), Ciconiiformes (Ci), Columbiformes (Co), Falconiformes (Fa), Galliformes (Ga), Gruiformes (Gr), and Passeriformes (Pa). Numbers following the order code refer to the reported continent of origin: Europe (1), Asia (2), Africa (3) Oceania (4), North America (5), South America (6) and unknown (9). The black triangle at the bottom of the tree represents a collapsed view of a large clade comprised of 120 lineages, 119 of those originating in passerines from all geographic regions of the world, except Oceania. The Columbiformes code (Co) appears in parentheses as this avian order was only attributed to one lineage in this clade.
