Main Methods:
- Establishment of human intestinal enteroid cultures.
- Cryopreservation of Cryptosporidium parvum-infected HCT-8 cell cultures within enteroids.
- Detailed procedures for the recovery and propagation of cryopreserved parasites using enteroids.
Main Results:
- Successful cryopreservation of Cryptosporidium oocysts within enteroid cultures.
- Demonstrated viability and infectivity of recovered parasites after thawing.
- Established a repeatable protocol for enteroid-based cryopreservation.
Conclusions:
- Enteroid-based cryopreservation offers a viable solution for storing Cryptosporidium oocysts.
- This protocol facilitates consistent access to viable parasites, supporting ongoing Cryptosporidium research.
