Open Access Highlights Chicken cells produce spherical while duck cells produce short filament virions.
Reduced infectious virus from duck cells is correlated with altered virus morphology. Actin disruption did not inhibit the production of filamentous virus by DEF cells. Viral progeny from chicken or duck cells has identical nucleotide sequences. Abstract Although wild ducks are considered to be the major reservoirs for most influenza A virus subtypes, they are typically resistant to the effects of the infection. Abbreviations Keywords.

Preventive Veterinary Medicine Volume 113, Issue 4, 1 March 2014, Using quantitative disease dynamics as a tool for guiding response to avian influenza in poultry in the United States of America. Open Access Abstract Wild birds are the primary source of genetic diversity for influenza A viruses that eventually emerge in poultry and humans.
Much progress has been made in the descriptive ecology of avian influenza viruses (AIVs), but contributions are less evident from quantitative studies (e.g., those including disease dynamic models). Transmission between host species, individuals and flocks has not been measured with sufficient accuracy to allow robust quantitative evaluation of alternate control protocols. We focused on the United States of America (USA) as a case study for determining the state of our quantitative knowledge of potential AIV emergence processes from wild hosts to poultry. Keywords.

Abstract Accumulating infections of highly pathogenic H5N1 avian influenza in humans underlines the need to track the ability of these viruses to spread among humans.
A human-transmissible avian influenza virus is expected to cause clusters of infections in humans living in close contact. Therefore, epidemiological analysis of infection clusters in human households is of key importance. Infection clusters may arise from transmission events from (i) the animal reservoir, (ii) humans who were infected by animals (primary human-to-human transmission), or (iii) humans who were infected by humans (secondary human-to-human transmission). Here we propose a method of analysing household infection data to detect changes in the transmissibility of avian influenza viruses in humans at an early stage. Author Summary Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans.

PLOS 11/11/14 Transfer of Maternal Antibodies against Avian Influenza Virus in Mallards (Anas platyrhynchos) Maternal antibodies protect chicks from infection with pathogens early in life and may impact pathogen dynamics due to the alteration of the proportion of susceptible individuals in a population.
We investigated the transfer of maternal antibodies against avian influenza virus (AIV) in a key AIV host species, the mallard (Anas platyrhynchos). Combining observations in both the field and in mallards kept in captivity, we connected maternal AIV antibody concentrations in eggs to (i) female body condition, (ii) female AIV antibody concentration, (iii) egg laying order, (iv) egg size and (v) embryo sex. We applied maternity analysis to the eggs collected in the field to account for intraspecific nest parasitism, which is reportedly high in Anseriformes, detecting parasitic eggs in one out of eight clutches. AIV antibody prevalence in free-living and captive females was respectively 48% and 56%, with 43% and 24% of the eggs receiving these antibodies maternally. Figures Introduction. Rev. Bras. Cienc.

Brazil presents privileged environmental conditions of reduced risk. In addition, all commercial poultry and conservation holdings are registered in state or national inventories and geographically located (GPS) for health control.

UNIVERSITY OF DENMARK - MARS 2011 - Thèse en ligne : Rapid detection of Avian Influenza Virus - Towards point of care diagnosis. Bird flu or Avian flu is an infectious disease caused by an influenza A virus of the Orthomyxoviridae family.
Avian influenza virus (AIV) causes significant economic losses to the poultry industry worldwide and threatens human life with a pandemic. Pandemic of AIV is the human infection caused by the appearance of a “new” influenza virus as a result of antigenic shift or antigenic drift. Several outbreaks of AIV caused by the rapid spread of infection have been identified.
Therefore, there is an urgent need for rapid diagnostic methods that would enable early detection and improve measurements to control the AIV outbreak. J Infect Dev Ctries 2011; 5(8):565-570.

Selection of peptides that interact with AIV Peptides selected from phage display library have been used as effective anti-microbial agents in previous studies . In this study, a 7-mer constrained phage displayed random peptide library containing about 3.7 × 109 different recombinant bacteriophages were used to select ligands that interact with the purified target molecule, AIV subtype H9N2.
Four rounds of panning were carried out, each with a slight increase in stringency to isolate high-affinity peptide ligands. Table 1 shows the heptapeptide sequences obtained from four rounds of panning the peptide library against AIV subtype H9N2. Seventeen out of 35 phages analysed from the fourth round represented the sequence NDFRSKT and other major sequences found in the final round of panning were LPYAAKH and ILGDKVG. Table 1.
