Abstract
The present invention provides a method for measuring oocyst of protozoa, such as, in an environment sample with high sensitivity at low cost within a short period of time; and a detecting reagent for use therein. Magnetic fine particles of 5 to 500 nm particle diameter having, immobilized thereto, binding factors for specific recognition of oocyst are added to an analyte containing a protozoan oocyst to form oocyst/binding factor/magnetic fine particle complexes by using a binding reaction to the oocyst, the formed complexes are recovered by a magnetic separation, and the protozoan oocysts contained in the complexes are assayed. Further, there is provided, for conducting the above method, a reagent for detecting protozoan oocysts comprising magnetic fine particles of 5 to 500 nm particle diameter having, immobilized thereto, antibodies against oocysts or binding factors for recognizing the antibodies.
