Results 36 electrophoresis samples (Picture 3.4 - 3.5 - 3.6) shows that 5/18 pairs have the same pattern of RFLP (recrudescence) accounting for 27.8% and 13/18 pairs have different pattern (reinfection) accounting for 72.2%. The reinfection rate is higher than recrudescence in our study are similar to those published in some developing countries.
