Risk factors and characteristics of low pathogenic avian influenza virus isolated from commercial poultry in Tunisia.

ABSTRACT:

Objective

Estimate the seroprevalence of influenza A virus in various commercial poultry farms and evaluate specific risk factors as well as analyze their genetic nature using molecular assays.

Materials and methods

This report summarizes the findings of a national survey realized from October 2010 to May 2011 on 800 flocks in 20 governorates. Serum samples were screened for the presence of specific influenza virus antibodies using cELISA test. Additionally, swab samples were tested by real time and conventional RT-PCR and compared with results obtained by others assays. Phylogenetic and genetic analyses of the glycoproteins were established for some strains.

Results

Out of the 800 chicken and turkey flocks tested by cELISA, 223 showed positive anti-NP antibodies (28.
