title: Detection of hepatitis A virus RNA in oyster meat.
abstract: Detection of low concentrations of viruses in shellfish is possible with nucleic acid amplification by PCR. Hepatitis A virus (HAV) has been detected in oyster meat by reverse transcription-PCR (RT-PCR). We developed a method to identify HAV RNA by RT-PCR of total RNA extracted from oyster meat contaminated by adsorption, bioaccumulation, or injection. With dot blot hybridization detection of amplicons from the RT-PCR, rapid screening of a large number of samples is feasible. As few as 8 PFU of HAV/g of oyster meat can be detected.
