Between January and August 2002, a total of 74 fishes belonging to nine species (Alburnus caeruleus, Barbus luteus, B. sharpeyi, Carassius auratus, C. carassius, Ctenopharyngodon idella, Cyprinus carpio, Hypophathalmichthys molitrix Liza abu) were collected from three fish farms south Baghdad. Twenty-six parasites observed.They following : Three protozoa ( Ichthyophthirius multifiliis , Trichot...

A total of 394 (255 males,139 females) live freshwater crayfish Astacus leptodactylus from four stations of Aras reservoir in West Azarbaijan Province (North-Western Iran) were studied during the winter until early autumn of 2009 for the presence of parasites, Epibionts and Fungal agents. Parasitological surveys were carried out on gills exoskeleton and internal organs, mycological examinations...

Abstract The leaf extract of C. alata showed antifungal activity by inhibiting five pathogenic fungi. Saprolegnia sp. attack was one type fungus that inhibits the hatchability eggs. leaves also can inhibit growth fungi on gouramy objective this study to determine effect and optimal concentration Cassia L. hatching rate, time, prevalence, survival silver barb eggs ( Barbonymus gonionotus ) infec...

Fish cells attached to hyphae were observed in brown trout Salmo trutta L. infected with Saprolegnia parasitica. Earlier studies with light microscopy indicated that these cells were lymphocytes and neutrophils and that they were involved in the defence mechanisms against Saprolegnia infections. However, using electron microscopy, we found these attached cells did not show leucocytic characteri...

An efficient synthesis of a series of 4'-oxyalkyl-isocordoin analogues (2-8) is reported for the first time. Their structures were confirmed by ¹H-NMR, 13C-NMR, and HRMS. Their anti-oomycete activity was evaluated by mycelium and spores inhibition assay against two selected pathogenic oomycetes strains: Saprolegnia parasitica and Saprolegnia australis. The entire series of isocordoin derivative...
