HCV variants were classified into six genotypes (1-6) subdivided into several subtypes with different geographic distribution worldwide. Previous studies conducted in Tunisia showed that genotype 1 counts for more than 80 % of circulating HCV genotypes and most of the isolates belong to subtype 1b. Genotype 2 comes in the second position, however, few sequences have been analyzed and published. In the present study, 89 isolates from Tunisian patients, typed as genotype 2 by the InnoLIPA commercial probe hybridization test, were sequenced in the NS5B and Core/E1 regions. All the isolates, clustered with the genotype 2 reference sequences, in the NS5B and in the Core/E1 region and the phylogenetic analyses in the two genomic regions were perfectly concordant: subtype 2c was the most frequent (58 out of 89, 65.1 %) and few isolates belonged to subtypes 2k(n = 10), 2i(n = 5), and 2b(n = 1). Fifteen isolates did not match with any of the reference sequences representing the genotype 2 subtypes, identified up-to-date. They divided into 2 separate clusters with high bootstrap values in both genomic regions. This study shows perfect concordance between the NS5B and the Core/E1 region suggesting that any of the two regions can be used for genotyping and that intergenotypic and intragenotypic recombinants are not very frequent, at least for HCV isolates from genotype 2. The present study also shows a predominance of subtype 2c among genotype 2 HCV isolates circulating in Tunisia, the co-circulation of minor subtypes (2k, 2i, and 2b) and proposes the possible existence of two other new subtypes.
