Detection of Norwalk virus and hepatitis A virus in shellfish tissues with the PCR.
A method for the detection of Norwalk virus and hepatitis A virus from shellfish tissues by PCR was developed. Virus was added to the stomach and hepatopancreatic tissues of oysters or hard-shell clams, and viral nucleic acids were purified by a modification of a previously described method (R.L. Atmar, T.G. Metcalf, F.H. Neill, and M.K. Estes, Appl. Environ. Microbiol. 59:631-635, 1993). The n...
متن کاملCollaborative evaluation of a method for the detection of Norwalk virus in shellfish tissues by PCR.
A multicenter, collaborative trial was performed to evaluate the reliability and reproducibility of a previously described method for the detection of Norwalk virus in shellfish tissues with the PCR (R.L. Atmar, F. H. Neill, J. L. Romalde, F. Le Guyader, C. M. Woodley, T. G. Metcalf, and M. K. Estes, Appl. Environ. Microbiol. 61:3014-3018, 1995). Virus was added to the stomachs and hepatopancre...
متن کاملDetection of norwalk-like virus in shellfish implicated in illness.
In the 1990s, Norwalk-like viruses (NLVs) were identified in patient specimens as the primary pathogen associated with shellfish-borne gastroenteritis in the United States. Identification of these viruses from implicated shellfish has been difficult due to inefficient recovery of viruses, natural polymerase chain reaction (PCR) inhibitors in shellfish, and low virus contamination. Recent improv...
متن کاملMolecular detection of hepatitis delta virus in blood donors with RT-PCR
Abstract Background and Objective: Hepatitis delta virus is an imperfect virus with RNA and its activity depends on the presence of hepatitis B virus. This virus can lead to acute and chronic diseases in the liver. This study aimed to detect the hepatitis delta virus in blood donors with positive Hepatitis B Surface Antigens (HBsAg). Material and Methods: In this Study, 350 serum sa...
متن کاملDetection and Genotyping of Hepatitis D Virus from HBsAg Positive Patients in Iran Using RT-PCR
Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...
