The present study was carried out to detect the genotype of E. histolytica that found in human fecal specimens and animals feces with Haemorrgic diarrhea by amplifying the SREHP gene, using RT-PCR technique, Cyber green dye and by fusion curve analysis. The study also included molecular detection of amoebic parasite species using Nested-PCR technology. The study recorded presence of parasites E. histolytica; E. dispar; E. bovis with total infection rates 82.9, 26.8, 4.9%, respectively. The study revealed the presence of E. histolytica parasite in five different genotypes (I, II, III, IV, V) with rate presence 9.75, 53.65, 19.5, 9.75, 7.3%, respectively. In conclusion, there are five genotype of E. histolytica, in human and animals, most of these genotypes may be infect any host, E. bovis was recorded in sheep and cows.
