Institute of Medical Microbiology and Immunology mia during follow-up between 5 months and 4 years. The other 60 patients remained negative in GBV-C PCR. Department of General Surgery One important route of GBV-C transmission is blood products (blood Department of Internal Medicine plasma and erythrocyte and thrombocyte concentrates). Therefore, we Department of Transfusion Medicine examined th...

UNLABELLED GB virus B (GBV-B), which is hepatotropic in experimentally infected small New World primates, is a member of the Hepacivirus genus but phylogenetically relatively distant from hepatitis C virus (HCV). To gain insights into the role and specificity of hepaciviral nonstructural protein 2 (NS2), which is required for HCV polyprotein processing and particle morphogenesis, we investigate...

We investigated the prevalence and genotypic distribution of GB virus-C/hepatitis G virus (GBV-C/HGV) and TT virus (TTV) in blood donors, mentally retarded children and four groups of patients living in Eastern Anatolia, Turkey. The prevalence and genetic analysis of TTV were determined by using the primers of the UTR and ORF1 regions of TTV, respectively. Reverse transcription nested (RT-n)-PC...

The strong similarity between GB virus B (GBV-B) and hepatitis C virus (HCV) makes tamarins infected by GBV-B an acceptable surrogate animal model for HCV infection. Even more attractive, for drug discovery purposes, is the idea of constructing chimeric viruses by inserting HCV genes of interest into a GBV-B genome frame. To accomplish this, infectious cDNA clones of both viruses must be availa...

To study mother-to-infant transmission of GB virus C/hepatitis G virus (GBV-C/HGV), blood samples of infants born to carrier mothers were collected beginning 3 months after birth and were tested for GBV-C/HGV RNA until 1 year of age. Of 2046 mothers, 2.1% were positive for GBV-C/HGV RNA, and 25 of their infants were followed for a median of 12 months. Thirteen infants (52%) were viremic, and in...

objective: gbv-c is a virus transmissible via blood transfusion and sexual routes. because of the shared transmission routes in gbv-c and hepatitis b virus (hbv) we have attempted to detect gbv-c in hbsag-positive patients using the more sensitive semi-nested pcr. we used restriction fragment length polymorphism (rflp) to determine genotype. methods: a total of 100 serum samples were collected...

GB virus B (GBV-B) is a recently discovered hepatotropic flavivirus that is distantly related to hepatitis C virus (HCV). We show here that translation of its polyprotein is initiated by internal entry of ribosomes on GBV-B RNA. We analyzed the translational activity of dicistronic RNA transcripts containing wild-type or mutated 5' nontranslated GBV-B RNA (5'NTR) segments, placed between the co...

The prevalence of GBV-C infection in voluntary blood donors and in groups at high risk for parenteral exposure to infectious agents was studied. The high risk groups included chronic renal failure patients on haemodialysis, renal transplant patients and haemophiliacs from Gauteng. The presence of GBV-C RNA in these populations was determined using reverse transcription polymerase chain reaction...

The issue of gender-based violence (GBV) against women in South Africa is prevalent mainstream and online social media. Women girls are targeted what seemingly becoming a prolonged cycle GBV the country. Human right activists, organisations, political leaders condemn this through various platforms, including Civil society have organised mobilised marches protests, tirelessly speaking out focus ...

GB virus B (GBV-B) is the closest relative to hepatitis C virus (HCV) with which it shares a common genome organization, however, unlike HCV in humans, it generally causes an acute resolving hepatitis in New World monkeys. It is important to understand the factors regulating the different disease profiles of the two viruses and in this regard, as well as playing a key role in viral RNA replicat...
