	abstract = {The viability of Cryptosporidium parvum oocysts and Ascaris suum eggs inoculated into aerobic and anaerobic digesters was measured. The digesters were maintained at 37{\textdegree}C, 47{\textdegree}C, and 55{\textdegree}C, with 10-day detention times. Eggs and oocysts were added to each digester in a single spike or in chambers placed in the digesters for varying periods. Oocysts were inactivated very rapidly in all systems as determined by a dye permeability assay, {\textgreater} 99\% inactivated after 10 days at 37{\textdegree}C, 4 days at 47{\textdegree}C, and 2 days at 55{\textdegree}C. Eggs were more rapidly inactivated in anaerobic digesters than in aerobic digesters. At 55{\textdegree}C, eggs in both anaerobic and aerobic digesters were {\textgreater} 99\% inactivated within 1 h. At 47{\textdegree}C, anaerobic digestion inactivated around 95\% eggs in 2 days, but around 25\% of the eggs were still viable after 10 days in aerobic digesters. At 37{\textdegree}C, anaerobic digestion inactivated more than 75\% of the eggs after 10 days, but in the aerobic digester at 37{\textdegree}C, 10 days of treatment had no effect on viability. The oocysts and eggs added in chambers appeared to behave similarly to these pathogens added directly to the biosolids within the digesters.},
