<prompt> Surface hemagglutination with adherence to glycoprotein act inHerpes virusInfluenza virusHepatitis-B virusCytomegala virus  <response>: Influenza virus 428-30- Ananthanarayanan 8th In the case of the Influenza viruses, the hemagglutinin on the virus surface gets attached to glycoprotein receptor sites on the surface of the respiratory epithelium.Other examples are, Human immuno deficiency virus, poliovirus Haemagglutin - surface antigen, strain specific, Antibody against this protective Neuraminidase - surface antigen, strain specific, Antibody not protective Hemagglutin - is glycoprotein, responsible for hemagglutination and hemadsorption Neuraminidase - is glycoprotein enzyme which destroys cell receptors by hydrolytic cleavageAntigenic shifts - Influenza virus A are because of genetic ressortment bw human and avian virusesAntigenic drifts - Influenza A B are because of point mutation during viral replication causes smaller epidemic only The phenomenon of genetic reassortment - can occure during influenza virus replication Pandemic strain Von- magnus-phenomenon - virus yield has high hamagglutination titre but low infectivity H5N1 is the Avian flue Influenza- A virus also called the Bird flue virus Micro-organism used as weapon in biological terrorism is small pox virusEmerging or Resurging diseases are Nipah virus H5N1 nv CJD. Australian bat Lyssa virus Ebola virus Hanta virus E. coli - 0157; H7 strain West Nile virus SARS Pertussis, diphtheria, anthrax, lagionaires disease, pandemic cholera, lassa fever, Rift valley fever, VRSA, and yellow fever Reys syndrome is commonly caused by Influenza type B Influenza vaccines administered through nasal drops Newer influenza vaccines - split virus vaccine, Neurominidase specific vaccine, Recombinant vaccinePost exposure prophylaxis is used in HIV Hepatitis A and B Rabies Tetanus H. influenza HIb Meningococcus Influenza-A Measles
