Abstract Surveillance of human immunodeficiency virus (HIV) molecular diversity and drug resistance-associated mutations (DRMs) among treatment-naive blood donors is critical for monitoring viral evolution and blood safety. From 2016-2017, 199 plasma samples were collected from 24 blood centers and confirmed as HIV viral load positive or serologically reactive in National Centers for Clinical Laboratories (NCCL), of which 179 were sequenced and subtyped in the gag, protease (PR)-reverse transcriptase (RT), integrase (IN) and/or envelope (env) regions. DRMs in PR-RT and IN regions were analyzed in Stanford HIVdb Program. The majority of subtypes were circulating recombinant form (CRF) 07_BC (34.6%) and CRF01_AE (32.4%); many unique recombinant forms (URFs) (39, 21.8%) and other rare CRFs were observed in the study. Notably, CRF02_AG and CRF06_cpx strains typically found in Africa were firstly identified amongst Chinese blood donors. DRMs were common, with 28 of 179 (15.6%) specimens carrying DRMs, including the PR N88S and RT K103N mutations, which have been implicated in elevated resistance to antiretroviral drugs. Furthermore, 4 HIV-1 isolates (2.4%, 4/168) had surveillance drug-resistance mutation (SDRM), including 3 nonnucleosidereverse transcriptase inhibitors (NNRTI) SDRMs (1 K101E, 2 K103N) and 1 protease inhibitor (PI) SDRM (M46I). The HIV viral diversity among blood donors observed in this study suggest that ongoing HIV-1 recombination is becoming progressively complex in China, and lots of DRMs found in the study exacerbate the primary drug resistance landscape, which highlight the necessity of timely genotypic drug resistance monitoring and molecular surveillance of HIV-1 among blood donors.

Mutation Information
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.
