Complete cryspovirus genome sequences from Cryptosporidium parvum isolate Iowa

Complete cryspovirus genome sequences from Cryptosporidium parvum isolate Iowa Bisegmented dsRNA viruses that infect most or all isolates of apicomplexan parasite Cryptosporidium parvum are currently assigned to a single species, Cryptosporidium parvum virus 1, in genus Cryspovirus, family Partitiviridae. An analysis of existing sequence data suggested that the complete sequences of both cryspovirus genome segments, dsRNA1 and dsRNA2, had yet to be determined. We therefore set out to accomplish this for the virus strain that infects C. parvum isolate Iowa. The results suggest that several previous cryspovirus sequences are indeed truncated at one or both segment termini and also identify sequences at or near the termini that are conserved in both segments. Complete sequences of other cryspovirus strains, including ones from other Cryptosporidium species, are needed for refining their classification into one or more virus species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

Bisegmented dsRNA viruses that infect most or all isolates of apicomplexan parasite Cryptosporidium parvum are currently assigned to a single species, Cryptosporidium parvum virus 1, in genus Cryspovirus, family Partitiviridae. An analysis of existing sequence data suggested that the complete sequences of both cryspovirus genome segments, dsRNA1 and dsRNA2, had yet to be determined. We therefore set out to accomplish this for the virus strain that infects C. parvum isolate Iowa. The results suggest that several previous cryspovirus sequences are indeed truncated at one or both segment termini and also identify sequences at or near the termini that are conserved in both segments. Complete sequences of other cryspovirus strains, including ones from other Cryptosporidium species, are needed for refining their classification into one or more virus species.
