| use of sequence analysis of the vp4 gene to classify recent vietnamese rotavirus isolates. | twenty-eight strains of p(8), four of p(4) and one of p(19) rotavirus, isolated in ho chi minh city, vietnam, during 2002-2003, were investigated by sequence analysis of the vp4 gene. seven of the 28 p(8) rotavirus vp4 sequences clustered in the p(8)-3 lineage, or the rare, so-called op354-like lineage. amino-acid sequence comparison revealed that vietnamese p(8)-3 rotaviruses were generally very similar to malawian strains, including the prototype op354 strain. the numerical severity scores of ... | 2008 | 18190567 |
