In the present study, Cryptosporidium parvum was diagnosed in stool by Z-N stain, ELISA and PCR. The detected cases were 5.3%, 8.3% and 9.6% by the previous three methods, respectively. The sensitivity, specificity and accuracy of the different techniques were evaluated. The Z-N stain showed the lowest sensitivity and accuracy in relation to either ELISA or PCR. Moreover, the study revealed that the sensitivity, specificity and accuracy of ELISA detection of Cryptosporidium in relation to detection of DNA in stool by PCR were 84.2%, 96% and 88.8%, respectively. Consequently, PCR showed the best results. From a practical point of view, ELISA is recommended for wide spread use in diagnosis of cryptosporidiosis. |
