| isolation and genetic characteristics of human genotype 1 japanese encephalitis virus, china, 2009. | several studies have shown that the predominant genotype of chinese japanese encephalitis virus (jev) is evolving from genotype 3 to genotype 1. however, in recent years, almost all genotype 1 isolates were from mosquitoes, and genotype 1 has been less associated with human disease than genotype 3. this study reports the isolation of human genotype 1 jev and its genetic characteristics to provide additional insights into human je pathogens that are currently circulating in china. | 2011 | 21283590 |
