31. Influenza viruses A, B and C represent the three antigenic types of influenza viruses. 32. Antigenic variation is common among pathogenic organisms.33. Many genes involved in antigenic variation are located in the subtelomeric regions of the chromosomes. 34. The Antigenics vaccine is custom-made for each patient from the cells of their tumors. 35. Elan and Antigenics are worthy companies. 36. These NICs collect specimens in their country, perform primary virus isolation and preliminary antigenic characterization. 37. In dengue fever, the effect of original antigenic sin has important implications for vaccine development. 38. H9N2 viruses isolated from chickens in China showed antigenic drift that evolved into distinct antigenic groups. 39. H9N2 viruses isolated from chickens in China showed antigenic drift that evolved into distinct antigenic groups. 40. AGEs are antigenic and represent many of the important neoantigens found in cooked or stored foods.
