Maximum likelihood phylogeny of the Enterocytozoonidae based on 1269 characters of aligned SSU rDNA sequence data. Maximum likelihood phylogeny of the Enterocytozoonidae based on 1269 characters of aligned SSU rDNA sequence data. Node A gives rise to a robustly supported clade (green box) that contains intranuclear microsporidian parasites of fish, some of which are known to also infect caligid copepods (blue box); Hepatospora eriocheir, forms an unsupported branch at the base of the fish clade. The sister clade to the fish-infecting group (red box) contains other genera isolated from crustacea and also higher vertebrates, and is well-supported from node B. Numbers at the nodes represent branching support using non-parametric bootstraping (ML 1000 replications) and Bayesian posterior probabilities, support values <50 for ML and <0.95 for Bayesian analyses are considered not supported (n/s). Fish abbreviations and accession numbers given in parentheses: LF lumpfish, CS chinook salmon, AH Atlantic halibut, RT rainbow trout, AS Atlantic salmon, ES English sole. Neoflabelliforma aurantiae is used as an outgroup and to root the tree.
