The genetic diversity of Cryptosporidium in reptiles was analyzed by PCR-restriction fragment
length polymorphism and sequence analysis of the small subunit rRNA gene. A total of 123 samples
were analyzed, of which 48 snake samples, 24 lizard samples, and 3 tortoise samples were
positive for CRYPTOSPORIDIUM: Nine different types of Cryptosporidium were found, including
Cryptosporidium serpentis, Cryptosporidium desert monitor genotype, Cryptosporidium muris,
Cryptosporidium parvum bovine and mouse genotypes, one C. serpentis-like parasite in a lizard,
two new Cryptosporidium spp. in snakes, and one new Cryptosporidium sp. in tortoises. C.
serpentis and the desert monitor genotype were the most common parasites and were found in both
snakes and lizards, whereas the C. muris and C. parvum parasites detected were probably the
result of ingestion of infected rodents. Sequence and biologic characterizations indicated that
the desert monitor genotype was Cryptosporidium saurophilu!
m. Two host-adapted C. serpentis genotypes were found in snakes and lizards.
