   The early phase of trichinellosis is difficult to diagnose due to the non-specificity of the signs and symptoms that may be mis - diagnosed as alimentary intoxication or enterobacterial infection. Therefore, it is important to study early diagnostic methods for Trichinella spiralis infection to allow medical intervention at early stages of the disease. Coproantigen has become an important alternative method for the diagnosis of intestinal infections caused by either protozoa or helminths. To investigate the sensitivity of coproantigen detection in comparison with other traditional serodiagnostics, the following techniques were performed on T. spiralis infected rats: examination of the stool for Trichinella adult or newborn larvae, detection of coproantigen by capture ELISA and PCR, ELISA for detection of Trichinella antibodies in serum and PCR for detection of Trichinella DNA in the serum. We found that Trichinel- la coproantigen by ELISA and PCR show positivity from 1st day until 9th day post infection (P.I.). PCR detected T. spiralis DNA in serum from 5th day P.I.. Trichinella antibodies in sera detected by ELISA technique show positivity starting from 10th day P.I. till the end of the experiment. No Trichinella adults or larvae were detected in stool. In conclusion, early diagnosis of T. spiralis showed higher sensitiv - ity by copro-PCR and copro-ELISA followed by detection of T. spiralis DNA in serum then detection of T. spiralis antibodies in serum.
