Detection of enteric viruses in shellfish from the Norwegian coast

Article Abstract:

Common blue mussels, horse mussels, and flat oysters obtained from various harvesting and commercial production sites along the Norwegian coast are screened for the presence of norovirus by a real time reverse transcription (RT)-nested PCR assay. The results indicate that mussels from the Norwegian coast can constitute a risk of infection with enteric viruses and that routine testing of samples may be justified.

Behavior of an aeromonas hydrophila aroA live vaccine in water microcosms

Article Abstract:

The survival of an aroA mutant of Aromonas hydrophila in aquatic microcosms prepared from fish water tanks is described. The results help to understand the behavior of aroA strain in natural environments and suggest that the inactivation of the aroA gene may be beneficial for the safety of this live vaccine for aquacultures.

Use of rotavirus-like particles as surrogates to evaluate virus persistence in shellfish

Article Abstract:

A demonstration that about 1 log(sub 10) of virus likes particles was depurated after one week in warm sea water at 22 degree Celsius by the use of nanopathogenic surrogate virus. The results of the demonstration suggest that viral particles may persist in shellfish tissue for several weeks.
