This study was conducted to determine the persistence of Giardia lamblia cysts in mixed septic tank effluent and swine manure slurry and to correlate fluorescein diacetate-propidium iodide staining of G. lamblia cysts with their morphology under low-voltage scanning electron microscopy. Under field conditions, G. lamblia cysts were degraded more rapidly in the mixed waste than in the control Dulbecco's phosphate-buffered saline (PBS). For total and viable cysts, the mixed waste had D values (time for a 90% reduction in number of cysts) of 18.3 and 15.5 days, and the Dulbecco's PBS control had D values of 41.6 and 26.8 days. The rates of cyst degradation in septic tank effluent and in Dulbecco's PBS were similar. Increasing the proportion of swine manure slurry in the mixed waste favored degradation of the parasite. These results indicate that the mixed waste treatment was the predominant factor affecting the cyst persistence and that it was swine manure slurry that played the role of degrading the parasite. Visualization of viable and nonviable Giardia cysts with low-voltage scanning electron microscopy revealed an excellent correlation between the viability of the cysts determined by fluorescein diacetate-propidium iodide staining and their electron microscopic morphology.
