background: mycobacterium marinum infection has a worldwide distribution and the organism occupies many aquatic environments. infections in human consist of nodular cutaneous lesions that can progress to tenosynovitis, arthritis, and osteomyelitis. case presentation: a 27-year-old man was presented with a history of swelling and exudative erythematous lesions and pustules of the right forearm. ...

It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. To learn more about the cellular processes that occur in the cells, scientists from the Aquatic Research Institute, Eawag, subje...

The Journal of Aquatic Animal Health serves the North American and international communities of scientists concerned with the health of aquatic organisms. We encourage the submission of papers dealing with the causes, effects, treatments, and prevention of diseases of marine and freshwater organisms, particularly fish and shellfish.We also welcomemanuscripts describing biochemical and physiolog...

Metals are essential cofactors for bio-chemical processes, including oxidative phosphorylation, gene regulation and free-radical homeostasis. Abnormalities in metal ions concentration in organisms, lead towards the eco-physiological hazards in the aquatics. In aquatic organisms, metal absorption involves transfer of metals to the circulatory system following: uptake by the apical membrane; move...

Background: Aquatic ecosystems are frequently subjected to contamination by toxic heavy metals and pesticides, yet very little is known about the influence of pesticides on bioaccumulation of heavy metals in aquatic organisms. Mercury is a toxic metal with no known biological benefit to organisms. Bioavailability of mercury in aquatic environments depends on biological and non-biological parame...
