In order to identify various Cryptosporidium species in environment, nested PCR-RFLP and DNA sequencing method were used. The sensitivity of nested PCR-RFLP based on 18s rRNA gene was shown to 1 oocyst. Therefore, we applied nested PCR-RFLP method to environmental samples. As a result, only 4 samples out of 8 samples confirmed as Cryptosporidium parvum by standard method of Cryptosporidium were identified as Cryptosporidium parvum by nested PCR-RFLP and DNA sequencing method. The rest of 4 samples among 8 samples were identified as Cryptosporidium muris , Cryptosporidium bailey . Therefore, in addition to standard method of Cryptosporidium , supplementary verification through nested PCR-RFLP and DNA sequencing should be needed to give more accurate information about risk of Cryptosporidium
