Mining oomycete proteomes for phosphatome leads to the identification of specific expanded phosphatases in oomycetes

Molecular Plant Pathology, Volume 25, Issue 3, March 2024.
This study provides the first comprehensive inventory of phosphatases in oomycetes and identifies an important phosphatase within the expanded serine/threonine phosphatase group in oomycetes. Abstract Phosphatases are important regulators of protein phosphorylation and various cellular processes, and they serve as counterparts to kinases. In this study,

Antigenic relationship between the animal and human pathogen Pythium insidiosum and nonpathogenic Pythium species [PDF]

Journal of Clinical Microbiology, 1987
Identification of the newly named pathogenic oomycete Pythium insidiosum and its differentiation from other Pythium species by morphologic criteria alone can be difficult and time-consuming. Antigenic analysis by fluorescent-antibody and immunodiffusion precipitin techniques demonstrated that the P.

Photodynamic therapy in Pythium insidiosum - an in vitro study of the correlation of sensitizer localization and cell death.

PLoS ONE, 2014
Pythiosis is an infectious disease caused by Pythium insidiosum, a fungus-like organism. Due to the lack of ergosterol on its cell membrane, antibiotic therapy is ineffective.
