Hepatitis C virus genotypes in hemodialysis patients in the Federal District, Brazil Genótipos do vírus da hepatite C em pacientes em hemodiálise no Distrito Federal, Brasil
Hepatitis C virus (HCV) genotypes and subtypes were determined in hemodialysis patients in the Federal District, Brazil, by sequencing of the 5' noncoding (NC) and nonstructural 5B (NS5B) regions. From 761 patients, 66 anti-HCV-positive samples were tested for HCV RNA. All 51 HCV RNA-positive s...
