    conserved pocket in the stem region shared with the diverse influenza subtyupes and function critical for viral fusion. Therefore, characterizing permitted evolutionary routes of the virus over the course of F10-type immune selection may serve as templates for the design of universal influenza vaccine and treatment strategies against all types of influenza viruses including those emergent pandemic strains. Selection of VN/04 (H5N1) or A/PR/8 virus escape mutants with F10 antibody was performed in MDCK

  • Influenza Virus Causes

    1843 Words  | 4 Pages

    Influenza is an acute respiratory illness caused by infection of influenza A and B viruses. The disease can affect both the upper and lower respiratory tract and is often followed by systemic signs and symptoms, such as: sudden onset of fever, chills, non-productive cough, myalgias (muscle pain), headache, nasal congestion, sore throat, and fatigue. (Cox et al.1998). Influenza viruses evolve continuously, challenging mammalian and avian hosts with new variants and causing complex epidemic patterns

  • Influenza Virus Prevention

    680 Words  | 2 Pages

    Influenza is caused by an RNA virus from the Orthomyxoviridae family (that consists of the genera influenza A, B, and C). Human influenza A and B viruses cause seasonal epidemics almost each winter within the United States. Influenza type B infects humans only, therefore it is unable of undergoing a mutation. Pandemics are caused solely by influenza A strains. The emergence of a new and completely different influenza virus to infect people will cause an influenza pandemic. Influenza kind C infections

    Introduction In 1918-19 approximately 50 million deaths were a detriment of the Spanish H1N1 virus pandemic; a respiratory virus. According to the World Health Organization, the second Influenza A H1N1 pandemic in 2009 spread to more than 200 countries causing more than 18 000 deaths. Before the World Health Organization had announced the official end of the pandemic in August 2010, in July 2009 the World Health Organization sent out a phase 6 warning that H1N1 could soon be a global pandemic.

    Jordan Richards BIOB 425 Paper #1 Assembly of endocytic machinery around individual influenza viruses during viral entry The purpose of this paper was to determine the entry method of influenza by tracking an individual influenza virus and endocytic structures in living cells. The main focus of entry was clathrin-mediated pathways and clathrin- and caveolin- independent pathways. These pathways were further researched to understand the development and use of clathrin-coated pits (CCP) and clathrin-coated

  • Influenza Virus: A Case Study

    916 Words  | 2 Pages

    Influenza viruses are constantly evolving due to the mechanism of antigenic drift. This results in seasonal vaccination to target only specific strains, which puts us in a race against the clock in the prevention of the next pandemic. One key to solving this is the development of a universal influenza vaccine, which would elicit a broad antibody response. This would target either multiple strains or strains from the past, present, and future in a single vaccination. As vaccine may target sites such

    Introduction The influenza virus is an RNA virus has an envelope that included members of the family Orthomyxoviridae. Its genome is a single negative strand segmented RNA. This virus consists of three types: A, B, and C. Influenza types A and B has eight segments of RNA, but the influenza virus type C only has 7 segments (Cheung and Poon, 2007).

    protein capsid is a protein layer that wraps around the virus. There are four basic shapes of viruses. The tobacco mosiac, adenovirus, influenza virus, and t-even bacteriophage are each examples of a different virus structure. Each individual protein subunit composing the capsid is a capsomere. The tobacco mosiac virus has a helical capsoid and is rod shaped. The adenovirus is polyhedral and has a protein spike at each vertex. The influenza virus is made of a flexible, helecal capsid. It has an outer
