Detection 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...
متن کاملClinical Impact and Frequency of Hepatitis D Virus Infection in HBsAg Positive Patients in a Southern Province of Iran (Kerman)
Background and Aims: Hepatitis D virus (HDV) can infect human population either as a superinfection or concurrent hepatitis B virus (HBV) infection. It is expected that presence of HDV infection is more prevalent in endemic HBV areas. Overall 5% of Iranian general populations are chronic HBV carriers. The aim of this study was to determine the seroprevalence of HDV and its clinical impact in ...
متن کاملPrevalence of Hepatitis B Virus, Genotypes, and Mutants in HBsAg-Positive Patients in Meerut, India
Background: Genetic changeability of hepatitis B virus (HBV) signifies a challenge for the sensitivity of immunologic and molecular diagnostics. Therefore, knowing the spread of HBV genotypes (GENs) and mutation has considerable impacts on treatment strategies, vaccination program, diagnosis, and prevention. The present study aimed to detect HBV GENs and mutants in HBsAg-positive patients. Meth...
متن کاملGenotype analysis of hepatitis delta virus from hepatitis B surface antigen-positive patients using PCR-RFLP in Tehran, Iran.
BACKGROUND Hepatitis delta virus is a unique human pathogen responsible for some 20 million infections globally. This virus is dependent on hepatitis B virus for transmission and propagation. Currently, at least three genotypes of hepatitis delta virus with different geographic distribution and clinical manifestations are described. METHODS In this study, hepatitis delta virus RNA of 35 patie...
