Multi-locus analysis of human infective Cryptosporidium species and subtypes using ten novel genetic loci [PDF]

, 2010
Background: Cryptosporidium is a protozoan parasite that causes diarrheal illness in a wide range of hosts including humans. Two species, C. parvum and C. hominis are of primary public health relevance. Genome sequences of these two species are available

Infection With Cryptosporidium hominis Provides Incomplete Protection of the Host Against Cryptosporidium parvum [PDF]

The Journal of Infectious Diseases, 2012
Cryptosporidium hominis and Cryptosporidium parvum, which infect humans equally, are genetically/antigenically almost identical. It remains unclear, however, whether infection with C. hominis protects against C. parvum. Gnotobiotic piglets were used to investigate cross-protection. After ≥3 days of recovery from C.
