Experimentally induced marine flexibacteriosis in Atlantic salmon smolts Salmo salar. II. Pathology.
The fish disease marine flexibacteriosis is characterised by necrotic lesions on the body, head, fins, and occasionally gills, with erosive lesions on the external surface as the prominent clinical sign. In Australia, the main species affected are Atlantic salmon Salmo salar and rainbow trout Oncorhynchus mykiss in sea-cage culture in Tasmania. Using a dose-dependent trial to determine patholog...
متن کاملTenacibaculosis infection in marine fish caused by Tenacibaculum maritimum: a review.
Tenacibaculum maritimum is the aetiological agent of an ulcerative disease known as tenacibaculosis, which affects a large number of marine fish species in the world and is of considerable economic significance to aquaculture producers. Problems associated with epizootics include high mortality rates, increased susceptibility to other pathogens, high labour costs of treatment and enormous expen...
متن کاملHistopathological 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 کاملEffects of episodic acidification on Atlantic salmon (Salmo salar) smolts
The effect of episodic acidification on Atlantic salmon (Salmo salar) smolt physiology and survival in fresh water (FW) and seawater (SW) was investigated. Smolts were held in either ambient (control, pH 6.0–6.6), acidified (chronic, pH 4.4–6.1), or episodically acidified (episodic, pH reduction from control levels to pH 5.2 for 48 h once weekly) river water for 31 days and then transferred to ...
متن کاملIron uptake mechanisms in the fish pathogen Tenacibaculum maritimum.
We present here the first evidence of the presence of iron uptake mechanisms in the bacterial fish pathogen Tenacibaculum maritimum. Representative strains of this species, with different serotypes and origins, were examined. All of them were able to grow in the presence of the chelating agent ethylenediamine-di-(o-hydroxyphenyl acetic acid) (EDDHA) and also produced siderophores. Cross-feeding...
