Histopathological study of gills in experimentally amoebic gill disease (AGD) infected Atlantic salmon, Salmo salar, L.
Amoebic gill disease (AGD) is the most important parasitic disease of Atlantic salmon industry inAustralia. Atlantic salmon (Salmo salar) experimentally infected with Neoparamoeba sp. apparently showedAGD gross signs on the gill and an amoebic-associated gill pathology. Physico-chemical factors of waterduring the experiment were monitored regularly and were approximately constant (temperature: ...
متن کاملAtlantic salmon (Salmo salar L.) exposed to cultured gill-derived Neoparamoeba branchiphila fail to develop amoebic gill disease (AGD)
Gill-derived Neoparamoeba spp. from Atlantic salmon cause amoebic gill disease (AGD) in naïve recipients. Atlantic salmon were inoculated with clonal gill-derived Neoparamoeba branchiphila that had been cultured in the presence or absence of Atlantic salmon cutaneous mucus. Neoparamoeba branchiphila did not elicit AGD and the supplementation of cultures with cutaneous mucus did not influence vi...
متن کاملAmoebic gill infections of rainbow trout in freshwater ponds
Gill disease of fry and fingerlings associated with extensive mortality in rainbow trout freshwater farms in Denmark have been observed on an increasing number of occasions in the latest years. Clinical symptoms of hyperventilation indicate respiratory distress. Gross-pathological observations of gills show pale nodules and patches on gill filaments. Histological and scanning electron microscop...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولBacterial Gill Disease
Bacterial gill disease (BGD) is a common external infection of hatcheryreared salmonids and occasionally of warm water species reared under intensive conditions. As defined by Wood (1974), the name of the disease describes the clinical signs of bacterial infections on the gills. The etiological agent of the disease is considered to be one or more species of filamentous bacteria including Flavob...
