Phylogenetic trees of NS5A and NS5B. Phylogenetic analyses of: NS5A (A); and NS5B (B) sequences performed using 500 bootstrap repetitions. Only bootstrap values >70% are outlined with black circles. Sequences from the present study are indicated with patient (Pt) number; HCV sequences from European countries in the Los Alamos database are shown with black triangles. The country and year of these sequences are reported after the genotype. The GT3a reference sequence (D17763, in black star) is included. Patients harboring NS5A-A30K are side marked. AU, Australia; CA, Canada; CH, Switzerland; CN, China; DE, Germany; FR, France; GB, Great Britain; IN, India; ITA, Italy; PK, Pakistan; US, United States; NZ, New Zealand.
