PG - 555-62 AB - There is little information on the epidemiology characterisation of HCV isolates in Tunisia. Previous report showed predominance of genotype 1b. In this study, 32 HCV isolates from genotypes 1a (n = 10), 1b (n = 14), 2 (n = 4), 3a (n = 3) and 4 (n = 1) were genotyped by sequencing and phylogenetic analysis on the non-structural 5b (NS5b) region. The isolates originated from 14 patients with chronic hepatitis, 10 haemophiliacs and eight healthy blood donors. NS5b sequence grouping was concordant with previous 5' untranslated region (5'UTR) genotyping results in 91% of cases. Most of the Tunisian isolates were closely related to the European ones, except for genotype 4 which seems to be related mostly to isolates from Egypt. Isolates from genotype 1a obtained from haemophiliacs showed distinct clustering and nucleic divergence from those obtained from non-haemophiliac patients, this underlines the particular mode of contamination of this group of patients.
