Eliminating of Pathogenic Soil Borne Pythium Species Spreading Across the Marine Port of Duba
Pythium species are considered the most important soil born fungi. They are facultative heterotrophic microorganisms. Under proper conditions, it become highly virulent to plants (depending on the species), causing many diseases, especially in the first stages of growth. These fungi abound in heavy agricultural soil and Egypt is an important source for such fungi that can be transmitted to anot...
متن کاملTiming Pseudomonas chlororaphis applications to control Pythium aphanidermatum, Pythium dissotocum, and root rot in hydroponic peppers
The ability of the microbial agent Pseudomonas (Ps.) chlororaphis Tx-1 to suppress Pythium aphanidermatum and Pythium dissotocum, and control root rot, was investigated as a function of time of agent application and pathogen inoculation in vegetativestage sweet peppers grown in single-plant hydroponic units. The agent was applied to the nutrient solution at 1 10 CFU/mL and roots were inoculated...
متن کاملPythium aphanidermatum infection following combat trauma.
Pythium aphanidermatum is a fungus-like plant pathogen which has never been reported as a cause of human infection. We report a case of P. aphanidermatum invasive wound infection in a 21-year-old male injured during combat operations in Afghanistan.
متن کاملPopulation Structure of Pythium irregulare, P. ultimum, and P. sylvaticum in Forest Nursery Soils of Oregon and Washington.
Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these concerns, a total of 115 isolates of three Pythium species (P....
متن کاملAspergillus terreus Inhibits Growth and Induces Morphological Abnormalities in Pythium aphanidermatum and Suppresses Pythium-Induced Damping-Off of Cucumber
The study investigated the efficacy of two isolates of Aspergillus terreus (65P and 9F) on the growth, morphology and pathogenicity of Pythium aphanidermatum on cucumber. In vitro tests showed that the two isolates inhibited the growth of P. aphanidermatum in culture. Investigating P. aphanidermatum hyphae close to the inhibition zone showed that the hyphae showed abnormal growth and loss of in...
