抗原漂移 meaning in English
antigeic drift
Examples
- Antigenic drifts minor changes of influenza viruses lead to the emergence of new viral strains every year
每年，流感病毒会出现抗原漂移轻微改变，并产生新病毒品种。 - Seasonal outbreaks of ordinary influenza arise as a result of influenza viruses undergoing minor genetic changes known as antigenic drift
普通流感的季节性爆发，是由流感病毒出现称为抗原漂移的轻微基因变异所引起。 - Cause seasonal outbreaks of ordinary influenza arise as a result of influenza viruses undergoing minor genetic changes known as antigenic drift
普通流感的季节性爆发，是由流感病毒出现称为抗原漂移的轻微基因变异所引起。 - The surface antigens of influenza viruses undergo frequent changes . such changes can be minor called antigenic drift or major called antigenic shift
流感病毒的表面抗原会常常改变，这些改变有时较小，称为抗原漂移antigenic drift ，有时则较大，称为抗原转移antigenic shift 。 - Two major hydrophilic peaks were conserved as well . however , there are two amino acid substitutions at positions 280 ( n to s ) and 290 ( m to l ) in the second minor hydrophilic peak of the strain zj2000 , which might have a critical effect on antigenecity
Jd1株在决定其抗原性的大小两个亲水区内高度保守，而zj2000株第二个小亲水区内280位氨基酸由s替代了n 、 290位l替代了m ，这两个突变可能与zj2000株的抗原漂移和毒力变异有关。
