Carboxymethylation of β-Glucan from Pythium insidiosum: Structural characterization and preliminary adsorption evaluation of DON and T2 toxin.

This study aimed to evaluate the impact of carboxymethylation on the structural and functional properties of β-glucan derived from the pathogenic oomycete Pythium insidiosum. β-Glucan was extracted and subjected to carboxymethylation (CM-glucan), with structural changes analyzed using C and H NMR spectroscopy. The modified β-glucan's ability to adsorb mycotoxins, specifically deoxynivalenol (DON) and T2 toxin, was assessed through in vitro adsorption assays.

Treating Pythiosis with Antibacterial Drugs Targeting Protein Synthesis: An Overview.

This review article explores the effectiveness of antibacterial drugs that inhibit protein synthesis in treating pythiosis, a difficult-to-treat infection caused by . The article highlights the susceptibility of to antibacterial drugs, such as macrolides, oxazolidinones, and tetracyclines. We examine various studies, including in vitro tests, experimental infection models, and clinical case reports.

Clioquinol and 8-hydroxyquinoline-5-sulfonamide derivatives damage the cell wall of Pythium insidiosum.

Aims: To evaluate the antimicrobial activity and to determine the pharmacodynamic characteristics of three 8-hydroxyquinoline derivatives (8-HQs) against Pythium insidiosum, the causative agent of pythiosis.

Methods And Results: Antimicrobial activity was tested by broth microdilution and MTT assays. The antimicrobial mode of action was investigated using sorbitol protection assay, ergosterol binding assay, and scanning electron microscopy.

Immunotherapy based on Pythium insidiosum mycelia drives a Th1/Th17 response in mice.

Pythium insidiosum is an oomycete that affects mammals, especially humans and horses, causing a difficult-to-treat disease. Typically, surgical interventions associated with antimicrobial therapy, immunotherapy, or both are the preferred treatment choices. PitiumVac® is a therapeutic vaccine prepared from the mycelial mass of P.
