ABSTRACT:
A process to excystate protozoal sporocysts involves treatment of an infected tissue sample with a sodium hypochlorite solution to stimulate excystation of the sporocysts from the tissue. Thereafter, removal of the sodium hypochlorite solution and treatment of the sample with a cell culture media as the excystation fluid eliminates incubation and subsequent washing steps using expensive reagents. The excystation fluid contains substantially no chelating agents, proteins, enzymes or bile acids.
