Gene flow and competitive exclusion of avian influenza A virus in natural reservoir hosts

Isolation and Identification of Avian Influenza Virus H9N2 Subtype

Immunologic Evaluation of DNA Vaccine Encoding Influenza Virus M2 Gene in Type A- Influenza Mice Model

Abstract Background and Objective: The M2 gene expressing the conserved protein in influenza virus can be used to make a single-dose vaccine with permanent immunity. Material and Methods: The mice were allocated to one case group immunized with pcDNA3-M2 and two control groups with pcDNA and PBS, in three dozes with interval of two weeks. Two weeks after the last injection, Cellular imm...

Standardization of ELISA for Detection of Avian Influenza Virus Antibodies

Comparing Competitive Fitness of West Nile Virus Strains in Avian and Mosquito Hosts

Enzootic transmission of West Nile virus (WNV; Flaviviridae, Flavivirus) involves various species of birds and ornithophilic mosquitoes. Single nucleotide substitutions in the WNV genome may impact viral fitness necessary for WNV adaptation and evolution as previously shown for the WN02 genotype. In an effort to study phenotypic change, we developed an in vivo fitness competition model in two b...

Evaluating the Immunogenicity of Avian Influenza Virus Nucleoprotein

  Background:  Influenza viruses cause Avian Influenza (AI) is a serious infectious disease belonging to type A Orthomyxovirus. A viral RNA synthesis is due to an interaction of the nucleoprotein (NP) with the viral polymerase. In the present study, we have evaluated the immunogenicity of avian influenza virus nucleoprotein.  Materials & Methods:   An Influenza Virus N9H2 subtype A/Chicken I...
