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

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 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 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.

Effects of Temperature and ph on Growth and Composition of Pythium Irregulare and Pythium Vexans
Mycologia, 1971Temperature and pH significantly affect the growth and composition of Pythium irregulare and P. vexans. The apparent optimum temperature for mycelial production by either fungus was lower in liquid medium than on agar, and P. irregulare produced greater amounts of mycelium than P. vexans under all conditions tested.

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,

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.

A molecular phylogeny of Pythium insidiosum
Mycological Research, 2003Sequence analysis of the ribosomal DNA internal transcribed spacers (ITS) was used to establish phylogenetic relationships among 23 isolates of Pythium insidiosum, the etiological agent of pythiosis in mammals. The isolates were divided into three distinct clades that exhibited significant geographic isolation. Clade I consisted of isolates from North,
