ABSTRACT
Cryptosporidium spp. is an important parasitic protozoa causing diarrhea which is a severe life-threatening diarrhea especially in immunocompromised hosts. We aimed to evaluate the usefulness of detection of Cryptosporidium spp. copro-antigen from fecal specimens by using enzyme linked immunosorbent assay (ELISA) test and comparing its sensitivity and specificity with some staining methods. The results revealed that Modified Acid-Fast stain is considered better than Giemsa in detecting Cryptosporidium species oocysts in faecal smears as their sensitivity were 67.5% and 53.75% respectively. On contrary, ELISA technique is considered the best method used for detection of cryptosporidial infection as its sensitivity is 90%.
