the 13+ species in the
Cryptosporidium genus have been confirmed as
causative agents of human disease.
Cryptosporidium is a
parasitic protozoan that is transmitted by multiple routes; the
animal host range is diverse. The following
species are currently accepted, on the basis of host
specificity, pathogenesis, morphology and genotyping:
C. parvum, C. wrairi, C. felis, C. canis, C. andersoni,
C. muris and C. ubiquitum
birds: C. baileyi, C.
reptiles: C. serpentis
fish: C. molnari
analyses have been largely based on sequencing of the small
subunit rRNA gene (18S rRNA), the hsp 70 gene, or other
housekeeping or structural genes. These analyses reveal that the
species interact in complex ways with hosts. For example, the
specific host of C. felis
is cats, but this species has also been isolated from a cow,
while C. andersoni
is morphologically close to C. muris but infects cattle rather than mice. And
C. parvum includes a
complex of subspecies that specifically infect cattle, pigs,
kangaroos, ferrets or monkeys.
