Pythium insidiosum complex hides a cryptic novel species: Pythium periculosum
Fungal Biology, 2022Early phylogenetic analysis of Pythium insidiosum, the etiologic agent of pythiosis in mammals, showed the presence of a complex comprising three monophyletic clusters. Two included isolates recovered from cases of pythiosis in the Americas (Cluster I) and Asia (Cluster II), whereas the third cluster included four diverged isolates three from humans in

AbstractA case of Pythium insidiosum keratitis is described. It is an unusual organism that is difficult to isolate. Cases in animals and humans have been reported from tropical and subtropical parts of the world but this is the first case from a temperate region and was acquired from a hot pool.

Pythium myriotylum and P. zingiberis have both been implicated in soft rot of ginger (Zingiber spp.). The status of these two taxa as distinct species follows original descriptions of physiology, morphology and pathogenicity. However, their status has been questioned by phylogenetic analyses. In this study, putative P.

Pythium rot of figmarigold (Lampranthus spectabile) caused by Pythium aphanidermatum
Journal of General Plant Pathology, 2007A new leaf rot disease was found on the leaves of figmarigold (Lampranthus spectabile). The causal organism, identified as Pythium aphanidermatum was found to cause the same symptoms after artificial inoculation and was then reisolated from the inoculated plants. We propose to name the disease Pythium rot of figmarigold.

Analysis by gas chromatography revealed the presence of small amounts of squalene, but not lanosterol nor ergosterol in Pythium paroecandrum, P. ultimum, P. graminicola, and P. arrhenomonas. However, when acetate-14C was used as a precursor for sterols, even squalene was not found in P. graminicola.

Pythium wilt of lettuce caused by Pythium uncinulatum in Japan
Journal of General Plant Pathology, 2010Pythium wilt of lettuce was found in two fields in Hyogo Prefecture, Japan in January 2007. On the basis of morphological characteristics and the rDNA-ITS sequences, the causal organism was identified as Pythium uncinulatum, unknown in Japan. A pot inoculation test demonstrated that P.

Investigations on the nature of the thallus in the Peronosporales have been confined to Phytophthora and Peronospora, in both of which complicated conditions exist within a single species. Studies on the sexual relations of species of Pythium with single zo6spore cultures have not been reported. Long cultural experience with the genus Pythium, however,
