rRNA gene array of L. major strain MHOM/IL/81/Friedlin. The sequence and annotations were taken from www.tritrypdb.org (LmjF chromosome 27, nucleotides 989640 to 998595; accessed on 10 August 2014). Arrows in blue indicate the 5′-to-3′ direction of the genes. The lower panel represents a more detailed view of the most relevant fragment for species typing. Regions used by different authors are indicated above (top) or below (bottom) each panel (24, 77, 102, 111, 112, 114, 116–118, 120–124, 126). The scale of the upper panel is given on the left. SSU, small ribosomal subunit rRNA gene (18S rRNA); LSU, large ribosomal subunit rRNA gene; ITS, internal transcribed spacer.
