Molecular phylogeny and taxonomy of Lagenidium-like oomycetes pathogenic to mammals.

Over the past twenty years, infections caused by previously unrecognised oomycete pathogens with morphological and molecular similarities to known Lagenidium species have been observed with increasing frequency, primarily in dogs but also in cats and humans. Three of these pathogens were formally described as Lagenidium giganteum forma caninum, Lagenidium deciduum, and Paralagenidium karlingii in advance of published phylogenetic verification. Due to the complex nature of Lagenidium taxonomy alongside recent reports of mammalian pathogenic species, these taxa needed to be verified with due consideration of the available data for Lagenidium and its allied genera.

Phytopythium: molecular phylogeny and systematics.

The genus Phytopythium (Peronosporales) has been described, but a complete circumscription has not yet been presented. In the present paper we provide molecular-based evidence that members of Pythium clade K as described by Lévesque & de Cock (2004) belong to Phytopythium. Maximum likelihood and Bayesian phylogenetic analysis of the nuclear ribosomal DNA (LSU and SSU) and mitochondrial DNA cytochrome oxidase subunit 1 (COI) as well as statistical analyses of pairwise distances strongly support the status of Phytopythium as a separate phylogenetic entity.
