Abstract The replication fidelity of reassortant A/Fujian/411/02(H3N2)-like influenza viruses was assessed by in vitro detection of escape mutants developing under selective pressure from monoclonal antibodies. The results showed A/Wyoming/3/03(H3N2) possessed lower fidelity relative to the A/California/7/04(H3N2) and A/Wisconsin/57/05(H3N2) viruses through the emergence of mutant viruses carrying H156Q hemagglutinin mutation which allows antibody escape. Using the neutralization assay to compare the fidelity of reassortant pandemic A/California/7/09(H1N1) viruses, the pandemic virus was shown to possess relative higher fidelity compared to A/Wyoming/3/03. This higher fidelity may contribute to the lack of major antigenic changes in the pandemic virus since the emergence in 2009.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
