Pythium insidiosum complex hides a cryptic novel species: Pythium periculosum

Fungal Biology, 2022
Early 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

Pythium insidiosum keratitis

Australian and New Zealand Journal of Ophthalmology, 1997
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, 2003
Sequence 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,

Enzymatic variability among Brazilian Pythium insidiosum isolates

Revista Iberoamericana de Micología, 2013
Pythium insidiosum is an oomycete classified in the kingdom Stramenopila. P. insidiosum hyphae are not able to initiate infection without the secretion of hydrolytic enzymes, which are considered an important factor in microbial virulence.To evaluate the extracellular enzymatic activity of 14 Brazilian P. insidiosum isolates and a standard strain (ATCC

Human Infectious Corneal Ulcer Caused by Pythium Insidiosum

Cornea, 1993
Pythium insidiosum is a fungus-like organism known to infect a variety of animals. In humans, the few known cases involving Pythium have included arterial infections and cellulitis. We present what we believe to be the first case of P. insidiosum recovered from a human corneal ulcer. The organism is difficult to isolate, causing delays in diagnosis. It
