Bayesian phylogeny constructed by using the cytochrome b sequences (479 bp) of Leucocytozoon parasites, including four sequences isolated from village chickens in Thailand (orange bold text) and other sequences deposited in the MalAvi database. Other Leucocytozoon lineages isolated from chickens are given in purple. Clade A contains sequences of Leucocytozoon macleani reported in other studies, while clade B contains sequences of L. macleani isolated from this study. MalAvi lineage codes and GenBank accession number are given after species name. Node values (in percentage) indicate the posterior clade probabilities.
