1. Encysted protozoan pathogens may require higher temperatures to remove any risk.2. The final hosts are infected by ingestion of raw vegetation or water containing encysted metacercaria. 3. The encysted metacercaria appears yellow, slightly oval spot, about 3 to 6 mm long. 4. There is some reason to do with bacteria going into encysted form; I forget the details. 5. The infective metacercaria are encysted and attached on plants, from which mammals get the infection through ingestion. 6. They undergo metamorphosis while encysted before dropping off the host and settling on the stream bed as juvenile creekshells. 7. On the other hand, encysted zoospores of P . colocasiae can survive for several months without a host. 8. As an example, artificial digestion is used to detect the presence of encysted trichinella larvae in suspected muscle tissue. 9. As with " T . canis ", encysted second stage larvae in pregnant or lactating cats become reactivated. 10. The glochidia lodge in the gills or fins of the fish and develop into juvenile mussels encysted in the fish tissue.
