Fig. 1. Phylogenetic relationships between 74 in Prevalence and molecular characterization of novel species of the Diplomonad genus Octomitus (Diplomonadida: Giardiinae) from wildlife in a New York watershed
Fig. 1. Phylogenetic relationships between 74 sequences of Octomitus representing 14 genotypes estimated by maximum likelihood analysis. The GTR + I + G model (gamma shape = 0.338, prop. invariable sites = 0.619) was chosen by jModelTest2 to be the best-fitting evolutionary model. Branches with less than 70% bootstrap support were not considered statistically robust and were collapsed during manual editing of the visualization. Inset: ML phylogeny computed from Octomitus genotypes aligned with the homologous region of available Diplomonad 18S rDNA sequences from Giardia, Spironucleus, Hexamita, Trimitus, and Enteromonas.
