Hypothesis
Are clinical manifestations associated with genotypes or subtypes of Cryptosporidium spp.?
Conclusion
Different genotypes and subtypes of Cryptosporidium spp. are linked to different clinical manifestations in children.
Supporting Evidence
- C. hominis was associated with diarrhea, nausea, vomiting, and general malaise.
- C. parvum, C. meleagridis, C. canis, and C. felis were associated with diarrhea only.
- Children infected with C. hominis subtype family Ib had more severe symptoms than those infected with other subtypes.
Takeaway
This study found that different types of Cryptosporidium can make kids sick in different ways, with some causing more symptoms than others.
Methodology

Potential Biases

Limitations
The study lacked data on other gastrointestinal pathogens and had small sample sizes for some analyses.
Participant Demographics
Children under 2 years of age from a community in Lima, Peru.
