Molecular Detection of Hepatitis C Virus (HCV) by Conventional One-step RT-PCR Coupled with Nested PCR

Molecular 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...

detection of hepatitis g virus(gbv-c),in chronic hepatitis c patient,by rt-nested pcr

background: hepatitis g virus (gbv-c) is a single strand rnapositive virus and is a member of flaviviridae family. infection with the virus is prevalent add has worldwide distribution. accurate diagnosis of the virus is very important, because of co-infection with other important viruses like hcv, hbv and hiv, it may influence on pathogenesis, disease progression and response to viral therapy. ...

the use of a sensitive rt-nested pcr method for detection of hepatitis c virus

objective: hepatitis c virus is the major cause of viral hepatitis and its diagnosis in suspected specimens is of great importance. the risk of transfusion- transmitted virus infection is primarily the result of failure in serological screening tests to detect recently infected donors in the pre-seroconversion window period of infection. therefore, sensitive and accurate diagnosis of hcv prior ...

Rapid detection and differentiation of Newcastle disease virus isolates by a triple one-step RT-PCR.

A triple one-step RT-PCR was developed to screen and differentiate virulent from avirulent Newcastle disease virus (NDV) isolates. Three sets of oligonucleotides were designed, each specific for amplifying NDV fusion protein gene-specific RNA from virulent, avirulent or all isolates respectively. The sensitivity of one-step RT-PCR was determined using viral RNA extracted from serially diluted N...
