Complete nucleotide sequences of two RNA segments of human picobirnavirus.
Picobirnaviruses are unclassified, non-enveloped, spherical, small viruses with a genome comprising two double-stranded RNA segments. Only incomplete sequence data on picobirnaviruses are available so far. By cloning involving single primer amplification, full-length cDNAs were prepared corresponding to RNA segments 1 and 2 of a picobirnavirus (strain Hy005102) isolated from a stool specimen from an infant with acute non-bacterial gastroenteritis in Thailand, and the complete nucleotide sequences were determined. RNA segments 1 and 2 are 2,525 and 1,745 base pairs in length, respectively. RNA segment 1 encodes two open reading frames (ORFs) of 224 and 552 amino acids, and RNA segment 2 codes for a single ORF of 534 amino acids. On comparison with a part of the nucleotide sequences of the RNA segment, 2 of the other published picobirnavirus strains, the Thai strain was found to be related most closely to one of the US strains.
