Background: Several serological assays are used for detection of a hydatid antigen in serum for diagnosis of cystic echinococcosis (CE). However, it requires technical expertise and is associated with the risk of acquiring blood-borne infections. Of late, interests have been shifted to other body fluids like urine, saliva, tear drops as alternate specimens in the diagnosis of CE. Aim: The aim of the study was to evaluate the dot enzyme-linked immunosorbent assay (Dot-ELISA) and electro-immunotransfer blot (EITB) for detection of a hydatid antigen in the urine for diagnosis of CE. Materials and Methods: 100 ml of urine samples were collected from the patients with confirmed CE (n=30), patients with suspected CE (n=30), patients with other diseases (n=30) and healthy controls (n=30). A hydatid antigen in urine was detected by Dot-ELISA and EITB using only polyclonal antibodies raised against a complete homogenate hydatid (CHH) antigen in rabbits. Results and Conclusions: The Dot-ELISA using polyclonal antibodies showed a sensitivity of 53.33% and specificity of 96.66%, whereas EITB showed a sensitivity of 46.66%. The Dot-ELISA and EITB employing polyclonal antibodies showed no significant difference in sensitivity (P=0.426). Hence, the Dot-ELISA being a simple procedure can be used for detection of a hydatid antigen in urine for diagnosis of CE.
