Table 7

Size of the IGSRE repetitive region of different Leishmania spp.

Species	Number of repetitive regions (IGSRE) inserted in each IGS rRNA region
	1st	2nd	3rd	4th	5th	6th
Leishmania major	8	12	15	37	28	10

The number of repetitions of the IGS rRNA region inserted in Chromosome 27 is shown in italics. The quantity of repetitions of the IGSRE region for each IGS rRNA region, by Leishmania species, is shown in bold numbers.
