antigenic variant meaning in English

抗原变体

Sequence comparison indicated that the nucleotide homologies between the ha gene and those from eight other h3 subtype sfv isolates from china are over 95 % , and nucleotide identities between h3 sfv isolates in china and a typical h3 subtype avian influenza virus ( aiv ) strain dkuk1 - 63 are 95 % to 100 % . these might tell us that the ha gene of all h3 subtype sives isolated in china was originally from aiv although the vaccine based on ha do not protect against different subtype of influenza virus , it can provide favorable resistance to infection with antigenic variants within a subtype
通过与其它7株国内siv分离株和6株genebank中的h3流感病毒ha序列比较分析，结果表明分离自我国不同地区的8株h3siv核苷酸序列同源性均在95 %以上，且与禽流感病毒( aiv )经典代表株dkuk - 63序列同源性在95 - 100 %之间，证实我国h3sivha基因来源于禽的流感病毒。
