ABSTRACT:A water‐sampling apparatus used for the isolation and detection ofGiardiacysts in water has been designed and tested. The sampling apparatus uses one of a variety of pumps or waterline pressure to move water through a filter. Two of the optional pumps are lightweight enough to make the apparatus portable and thus suitable for sampling in remote areas. This technique of sample processing produces good cyst recovery in much less time than is required with previously established methods.Giardiacysts are identified using direct immunofluorescenc
