Molecular surveillance of enterovirus and Norwalk-like virus in oysters relocated to a municipal-sewage-impacted Gulf estuary

Article Abstract:

The prevalence of enteric viruses and their relationship to indicators in environmentally polluted shellfish was examined by conducting an 18-month survey. Results state that enteric viral sequences were found in contaminated oysters throughout all seasons except hot summer, with a high prevalence of Norwalk-like-viruses (NLV) than enterovirus.

High-pressure inactivation of hepatitis A virus within oyster

Article Abstract:

The potential of high hydrostatic pressure (HHP) to inactivate hepatitis A virus (HAV) directly within shucked oyster meats after contamination with HAV in a flowthrough natural seawater system is investigated. It is found that bioconcentration of nearly 6 log(sub 10) PFU of HAV per oyster was achieved under simulated natural conditions.

A method to detect low levels of enteric viruses in contaminated oysters

Article Abstract:

Research on processing procedures conducted to extract enteric viruses from oysters for PCR detection is presented. The method included improves the gastroenteritis outbreak response.
