BACKGROUND From January 2002 to May 2004, 28 puffer fish poisoning (PFP) cases in Florida, New Jersey, Virginia, and New York were linked to the Indian River Lagoon (IRL) in Florida. Saxitoxins (STXs) of unknown source were first identified in fillet remnants from a New Jersey PFP case in 2002. METHODS We used the standard mouse bioassay (MBA), receptor binding assay (RBA), mouse neuroblastom...
Infections by virulent strains of Vibrio parahaemolyticus are frequently reported in Southeast Asia. This is due to the frequent seafood contamination by virulent strains. In this study conducted from 2008 to 2011, seafood like fish, shrimp, squid, crab, and molluscan shellfish were purchased from provinces in Thailand and three Southeast Asian countries and examined for the prevalence of three...
Fish parasites constitute widely diversified groups of unicellular and multicellular organisms. Recently, less known parasite groups have emerged as serious pathogens. Firstly, infection with dinoflagellates of the genus Ichthyodinium has been found during seed production of leopard coral grouper, Plectoropomus leopardus, in Japan and yellowfin tuna, Thunnus albacares, in Indonesia. Schizonts m...
Viral pollution in shellfish has been analyzed simultaneously across a wide range of geographical regions, with emphasis on the concomitant variations in physicochemical characteristics and social features. The methods for sample treatment and for the detection of human enteric viruses were optimized by the participating laboratories. The second part of this study involves the selection of a pr...
background: the plerocercoid stage of pseudophyllideancestoda infected a wide range of fresh water fish,particularly the members of the cyprinidae family. the parasitespecies are the most common pathogens that have severe effectson fish. objectives: the aim of the present study is todetermine the occurrence and distribution of the plerocercoid ofdiphyllobothriidae in two freshwater fish from no...
The term ichthyosarcotoxism describes a variety of conditions arising as the result of poisoning by fish flesh. Poisoning by shellfish and other invertebrates is excluded, as is bacterial food poisoning from contaminated fish. Although most of the conditions are experienced mainly in warmer climates than Britain's, one form of fish poisoning is relatively common here, and others may be imported...
When filter-feeding shellfish are consumed raw, because of their ability to concentrate and store waterborne pathogens, they are being increasingly associated with human gastroenteritis and have become recognized as important pathogen vectors. In the shellfish industry, UV depuration procedures are mandatory to reduce pathogen levels prior to human consumption. However, these guidelines are bas...
Restored shellfish reefs provide valuable habitat for fish, but it is not clear how different approaches affect performance, and either promote the development of new fish populations (i.e. “production”) or simply attract individuals from broader seascape “attraction”). We measured effects a 1.5 ha reef restoration site on assemblages in Pumicestone Passage eastern Australia, which contains rep...
