Giardiasis is an intestinal parasitosis affecting dogs and able to infect human beings. Its diagnosis can not be done with the only clinical signs, the main of which is non characteristic diarrhoea. It implicates to perform further tests to detect the parasite. The zinc sulfate concentration technique (ZSCT) is the more effective one if performed on two or three successive days. Fecal ELISA kits have been developed to detect Giardia in humans and were found to be less sensitive than the ZSCT in dogs. In this study, we used 30 infected Beagles to compare the sensitivity of one, two or three fecal examinations following ZSCT and one or two ELISA tests. We conclude that if a single ZSCT is insufficient, two or three ZSCT and one or two ELISA using the commercial kit ProSpecT® Giardia have almost the same sensitivity.
