Molecular epidemiology of hepatitis C infection in Cyprus: evidence of polyphyletic infection.

چکیده
The genetic diversity of the hepatitis C virus (HCV) in Cyprus is investigated for the first time in this study. Nucleotide sequence analysis of the CORE-E1 and NS5B regions of the HCV genome was performed on blood plasma samples obtained from 77 HCV patients in Cyprus, collected during 2005-2008. The amplified products were sequenced and compared to reference HCV strains of known genotype and subtype in order to classify the isolates found in this study. Genotype could be determined for all strains, and subtype for all but four isolates. Phylogenetic analysis revealed that 51 patients were genotype 1, of which 38 were subtype 1b, 9 were 1a, and 1 was unclassified, one patient was genotype 2c, 13 were genotype 3a, nine were genotype 4, of which six were subtype 4a, and three were of unclassified subtype, one was genotype 5a, two patients seem to carry a possible 2k/1b recombinant strain, and no genotype 6 strains were found. This study demonstrated a genetic heterogeneity of HCV infection in Cyprus, with five of the six known HCV genotypes on the island, including unclassified isolates in genotypes 1 and 4, and also the apparent introduction of the 2k/1b recombinant strain in intravenous drug users.

Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...
