Molecular characterization of Entamoeba, Blastocystis and Cryptosporidium species in stool samples collected from Jordanian patients suffering from gastroenteritis

Abstract

Little is known about the prevalence of intestinal protozoa in patients suffering from diarrhea in Jordan. The present study aimed to detect and speciate Entamoeba, Blastocystis, and Cryptosporidium species in a total of 159 human patients with diarrhea from November 2014 to October 2016. The overall prevalence for the three parasites was 19.5% (31/159). Entamoeba spp. (Entamoeba. dispar and/or Entamoeba histolytica), Blastocystis hominis, and Cryptosporidium parvum subtype IIaA15G2R1 were detected in 12.6%, 6%, and 0.6 of samples, respectively. This is the first molecular study in Jordan to confirm the diagnosis of Entamoeba species and to discriminate between E. histolytica and E. dispar.
