  • Nonspecific reactions, hypergammaglobulinemia, or the presence of antibodies directed to other infectious agents that may be antigenically similar to HIV can produce false positive results. (wikipedia.org)
  • humans
  • I had indeed wondered why, as reported many years ago, humans sera contain natural antibodies with detectable in vitro activity against VSV, whereas sera from my naive mice never did. (virology.ws)
  • Transmission of the virus from pigs to humans is not common and does not always lead to human flu, often resulting only in the production of antibodies in the blood. (wikipedia.org)
  • subtype
  • A universal flu vaccine is flu vaccine that is effective against all influenza virus strains regardless of the virus subtype or viral genetic drift. (wikipedia.org)
  • adaptive
  • Work on adaptive immunity focuses on B lymphocytes and antibodies to HIV-1, while work on innate immunity focuses on dendritic cells. (wikipedia.org)
  • virus
  • Evidence suggests viral presence in mature erythrocytes is a result of replication of the virus in hematopoitic erythrocyte precursor cells and simultaneous maturation of the infected immature cells rather than of direct entry and replication of CTFV in mature erythrocytes. (wikipedia.org)
  • Blood samples are tested for viral RNA, viral antibodies or for the virus itself to confirm the diagnosis. (wikipedia.org)
