title: Cryptosporidium systematics and implications for public health.
abstract: There is controversy in the taxonomy of Cryptosporidium parasites and the public health significance of Cryptosporidium isolates from various animals. Recent advances in molecular characterization of Cryptosporidium parasites have allowed the re-examination of species structure of the genus Cryptosporidium. Non-parvum Cryptosporidium spp and new C. parvum genotypes in immunocompromised humans can now be clearly detected. In this article, Lihua Xiao and colleagues summarize the current biological and molecular evidence for different Cryptosporidium spp, and the public health importance of these species and new C. parvum genotypes.
