Abstract:
                                      Objective: To explore the prompt methods in determination of viability of the adult of 
Trichinella spiralis. 
Methods: The adult worms of 
Trichinella spiralis were stained with 0.5% safranine,1.0% neutral red or 0.5% methylene blue. 
Results: The dead adults were observed when stained with 0.5% safranine or 1.0% neutral red in the study. The vital adults were unstained with all three stains. 
Conclusions: Both 0.5% safranine staining and 1.0% neutral red staining are prompt method in determination of viability of the adult of 
Trichinella spiralis.
