saprolegnia is one of? the? ?most important agents decreasing the eggs survival rate in sturgeon hatcheries. there are some chemical substances for controlling the fungal infection of eggs. in this study, an attempt was made to introduce a ?germ negative bacterium, pseudomonas aeroginosa (ptcc1430)(persian type culture collection) as a biocontrol??ling agent of? ?water mold. saprolegnia was iso...
Emerging fungal and oomycete pathogens are increasingly threatening animals and plants globally. Amongst oomycetes, Saprolegnia species adversely affect wild and cultivated populations of amphibians and fish, leading to substantial reductions in biodiversity and food productivity. With the ban of several chemical control measures, new sustainable methods are needed to mitigate Saprolegnia infec...
Animals and plants are increasingly threatened by emerging fungal and oomycete diseases. Amongst oomycetes, Saprolegnia species cause population declines in aquatic animals, especially fish and amphibians, resulting in significant perturbation in biodiversity, ecological balance and food security. Due to the prohibition of several chemical control agents, novel sustainable measures are required...
The endoplasmic reticulum of Saprolegnia, Dictyuchus, Synura and Cryptomonas may contain tubules less than 20 nm in diameter. In Saprolegnia these tubules have a maximum length of 1-6/tin, a wall of a single layer of colchicine-resistant, osmiophilic subunits, and a tapering end-piece. Flimmer hairs (flagellar hairs) are morphologically similar and are attached to the flagellum sheath by a tape...
