Pythium species are morphologically polymorphic, physiologically unique and ecologically versatile, which make them significant both theoretically and practically. They are ubiquitous in soil and in water, distributed worldwide, and with very diverse host ranges. They include some of the most important and destructive plant pathogens, causing losses of seeds, pre-emergence and post-emergence da...

Pythium insidiosum, the only species in the genus that infects mammals, is the etiological agent of pythiosis, a granulomatous disease characterized by cutaneous and subcutaneous lesions and vascular diseases. Accurate diagnosis of pythiosis and identification of its causal agent are often inconsistent with current immunological diagnostic methods. A species-specific DNA probe was constructed b...

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. The conventional treatment is surgery, but lesion recurrence is frequent, requiring several resections or limb amputation. Photodynamic therapy uses photo-activation of drugs and has the potential to be an attractive alte...

Pythium insidiosum is a protoctista and causes diseases in plants and animals. In Thailand it can cause a unique human infection of three types. The first type is a subcutaneous lesion in thalassaemic patients, with the pathological findings of a granulomatous reaction, diffuse infiltration, and oedema of the vessel walls. The patients responded to a saturated solution of potassium iodide. The ...

Introduction Pythiosis is caused by Pythium insidiosum, a fungus-like organism in the class Oomycetes. It can infect humans and a variety of animal species in tropical, subtropical and some temperate regions. Cases of animal pythiosis have occurred predominantly in horses in the skin and subcutaneous tissue at the limbs and in the ventral portion of thoracoabdominal wall - lesions in the nasal ...

Pythium attrantheridium sp. nov. is a new species isolated from cavity spot lesions of carrots as well as apple and cherry seedlings from various locations widely distributed in Canada and the USA. This fungus is closely related to the heterothallic P. intermedium, but is distinguished by: (1) unique molecular characteristics; (2) unique morphological characteristics; and (3) mating incompatibi...

Los Oomycetes son un grupo de organismos que alberga géneros y especies destructivas plantas cultivadas silvestres. En México, especialmente en el Estado Sinaloa, la información sobre esos su presencia aguas superficiales empleadas para uso agrícola es escasa. Esta investigación se realizó con objetivo determinar del género Pythium irrigación Valle Culiacán, México. De septiembre 2018 a enero 2...

The objectives were to evaluate the effects of increasing metal micronutrient concentrations and silicon (Si) on plant growth susceptibility Pythium root rot with hydroponically grown lettuce (Lactuca sativa). In first experiment, was in hydroponic solutions micronutrients iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) supplied at either 0, 2.5, 5, or 10 mg∙L−1. A standard commercial solutio...
