Modelling the hepatitis C with different types of virus genome.

چکیده
Hepatitis C virus (HCV) is one of the leading known causes of liver disease in the world. The HCV is a single-stranded RNA virus. The genomes of HCV display significant sequence heterogeneity and have been classified into types and subtypes. Types from 1 to 11 have so far been recognized, each type having a variable number of subtypes. It has been confirmed that 90% approximately of the isolates HCV infections in Egypt belong to a single subtype (4a) [10]. In this paper, we construct a mathematical model to study the spread of HCV-subtype 4a amongst the Egyptian population. The relation between HCV-subtype 4a and the other subtypes has also been studied. The values of reproduction numbers R (01), R (02) have been derived [5]. Also, threshold conditions for the value of the transmission rates k (1) and k (02), in terms of R (01), R (02) and the mutation factor μ have been determined to insure that the disease will die out. If the conditions fail to happen the disease takes off and becomes endemic.

متن کاملThe Full Length Hepatitis C Virus Polyprotein and Interactions with the Interferon-Beta Signalling Pathways in vitro
Background: Hepatitis C is a global health problem. The exact mechanisms by which hepatitis C virus (HCV) can evade the host immune system have become controversial. Whether HCV polyproteins modulate IFN signalling pathways or HCV proteins are responsible for such a property is the subject of interest. Therefore, an efficient baculovirus delivery system was developed to introduce the whole geno...

Abstract: Genotyping of the hepatitis C virus (HCV) is important for designing therapeutic strategies and regional specific diagnostic assays. The aim of this study was to identify the HCV genotypes in HCV infected blood donors. This is the first report on HCV genotypes in blood donors in Iran. In this cross-sectional study, 103 blood donors with hepatitis C were investigated for HCV genotype...

Background and Aims: Torque teno virus (TTV) is a DNA virus that isolated from the serum of a Japanese patient without A-G transfusion-transmitted hepatitis and other etiology. TTV is detectable in plasma and peripheral blood mononuclear cells, different body fluids and secretions such as stools, saliva, semen, vaginal fluid. The genome exhibits high diversity that has enabled the determination...
