A few granules with autofluorescence were detected in the living embryonated eggs of Trichuris suis by the epi-fluorescence microscopy observation technique, however, they were not detected in dead ones. This technique is useful for the identification of the viability for the embryonated eggs which showed the normal morphology under a visible light microscope. This observation technique is advantage to check the safety for the sawdust litter which contained the embryonated Trichuris eggs.
