| sequences of e/ns1 gene junction from four dengue-2 viruses of northeastern thailand and their evolutionary relationships with other dengue-2 viruses. | we determined the 240-nucleotide sequences of the e/ns1 gene junction of four dengue-2 viruses by the primer extension dideoxy chain termination method. these viruses were isolated from dengue patients with different clinical severities in nakhon phanom, northeastern thailand in 1993. the results were compared with the 52 published dengue-2 sequences of the same gene region. sequence divergence of four new isolates varied from 4.17% to 5.42% compared with dengue-2 prototype new guinea c strain w ... | 1995 | 7494497 |
