摘要：

The genomic M segment of Seoul 80-39 virus was characterized by cloning and nucleotide sequence analysis. The virion M RNA segment is 3651 nucleotides long with the 3' and 5' terminal sequences inversely complementary for 20 bases. A single open reading frame was detected in the viral complementary-sense RNA which can encode a polypeptide of 1133 amino acids. The Seoul 80-39 virus M segment was compared with the M segments of related viruses, Hantaan 76-118, Hallnas B1 and Sapporo Rat (SR-11) virus. Our results demonstrate a significant similarity between M RNA segments of the Seoul 80-39, Hantaan 76-118, Hallnas B1 and SR-11 viruses. The degree of conservation of both nucleic acid and protein sequences between these viruses reveals a close evolutionary relationship. Furthermore, it is evident that the serotypic profile of hantaviruses is determined by the rodent host species from which the virus was isolated and not by the geographical area.
