| a novel salifa-saprolegnia association. | during the period from december 2006 to march 2007, about 1000 freshwater leeches, salifa delicata, were collected from al-sont canal, adjacent to assiut city, egypt. in the laboratory, 96% of salifa delicata showed signs of oomycotal infection (cotton-wool like appearance radiating out in whorled pattern) and died within 3 days. direct microscopy and culture proved saprolegnia hypogyna to be the pathogen. histopathological studies showed necrotic lesions, destruction of cuticle, epidermis, derm ... | 2009 | 19285503 |
| saprolegnia strains isolated from river insects and amphipods are broad spectrum pathogens. | saprolegnia species are destructive pathogens to many aquatic organisms and are found in most parts of the world. reports based on phylogenetic analysis suggest that saprolegnia strains isolated from aquatic animals such as crustaceans and frogs are close to saprolegnia strains isolated from infected fish or fish eggs and vice versa. however, it has often been assumed that host specificity occurs for each individual isolate or strain. here we demonstrate that saprolegnia spp. can have multiple h ... | 2014 | 24295914 |
