Abstract
The cDNA of RNA segment coding for VP7 of human rotavirus isolated from patient's stool at Seoul area was synthesized, amplified by polymerase chain reaction, field in with Klenow fragment of DNA polymerase I and cloned into pUC19. The cDNA sequence was determined and compared with that of VP7 coding RNA segments of group A rotaviruses isolates in foreign country. Over 90% sequence homology was found with serotyppe I sepcific WA1 and RE9 strains. Comparative analysis of the deduced amino acid sequences within the two variable regions (amino acid residue 87 through 101 and 208 through 221) with WA1 and RE9 strains also showed high degree of sequence similarity with each other.
서울지역의 소아설사환자가 가검물로부터 분리한 로타바이러스의 VP7을 코딩하는 RNA분절 cDNA를 합성한 후 로타바이러스 혈청형1인 WA1과 RE9의 아홉 번째 RNA분절과 비교하였더니 90%이상의 유사성을 보였다. 염기서열로부터 유추된 아미노산 서열중 혈청간에 변이가 많은 VR5와 VR8 지역을 비교한 결과 역시 혈청형 1인 RE9과 WA1 바이러스주와 매우 높은 유사성을 지님을 알 수 있었다.
