Here we describe the first application of transient gene silencing in Saprolegnia parasitica, a pathogenic oomycete that infects a wide range of fish, amphibians, and crustaceans. A gene encoding a putative tyrosinase from S. parasitica, SpTyr, was selected to investigate the suitability of RNA-interference (RNAi) to functionally characterize genes of this economically important pathogen. Tyros...

Odontesthes bonariensis is a freshwater teleost fish from the Pampean inland waters, with an important economic potencial. The conditions of its intensive culture systems favour the proliferation of pathogen agents. This work describes the ocurrence of Achlya racemosa Hildebrand on eggs, and of Saprolegnia ferax (Gruith.) Thuret on a juvenile of Argentinian silverside (Odonthestes bonariensis)....

Haemato-biochemical studies in rainbow trout infected with Saprolegnia were carried out under temperate climatic conditions of Kashmir valley to find out the variation in blood parameters. The trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. The same experiment was carried out on 2,70000.00 trout fish eggs from No...
