Detection of Hepatitis B Virus in Used Razor Blades by PCR
BACKGROUND AND AIMS Hepatitis B virus (HBV) infection ranks among the most devastating health problems in the world.The most probable transmission routes of HBV are blood contact, sexual, and horizontal transfer. Other sources of HBV transmission are razor sharing, beauty treatments, tattooing, piercing, and manicures and other chiropody treatments.Many infections have been reported in South-Ea...
متن کاملThe Study of Cerumen Hepatitis B Infection in Chronic Hepatitis B Patients by Real-Time PCR
Introduction: The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including se...
متن کاملQuantitative PCR for hepatitis B virus with colorimetric detection.
A novel, sensitive colorimetric test is described for quantification of the initial number of hepatitis B virus (HBV) genomes amplified in PCR. The viral genomes are amplified together with a synthetic internal standard (IS) to correct for the variability of the efficiency factor. One of the two primers is biotinylated, and the amplified mixtures of HBV and IS DNAs are bound to streptavidin-coa...
متن کاملDetection of SENV Virus in Healthy, Hepatitis B- and Hepatitis C-Infected Individuals in Yazd Province, Iran
Background: SEN virus (SENV) is the latest virus proposed as a cause of unknown hepatitis cases. Among nine detected genotypes of the virus, genotypes D and H are more frequent in hepatitis cases of unknown origin. The aim of this study was to determine the frequency of SENV-D and SENV-H genotypes in the sera of healthy individuals and hepatitis B and C patients. Methods: Totally, 200 serum sam...
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...
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...
