background and aims: hemagglutinin (ha) protein of avian influenza (ai) plays an essential role in the virus pathogenicity. ai h9n2 subtype causes significant economic loss in broiler and layer in poultry farms in iran. ai viruses have a great involvement in evolutionary changes at nucleotide and amino acid levels and vaccines could induce faster rates of such changes. up-dated understanding of...
the polymerase chain reaction (pcr) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. avipoxvirus (apv) specific dna was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from tehran province. sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...
Avian influenza is one of the most important diseases in avian industry, which also threats human population. Thus, vaccination is necessary for controlling this viral disease. In this study, killed vaccine of avian influenza subtype H9N2 and formalin solution (for virus inactivation) were used. It is necessary to study the effect of different factors such as formalin concentration, as well as ...
In this study, we determined if the sensitivity of the currently available in vitro test to detect bovine tuberculosis could be enhanced by adding the following immunomodulators: interleukin-2 (IL-2); granulocyte-macrophage colony-stimulating factor (GM-CSF); antibodies neutralizing IL-10 and transforming growth factor beta (TGF-beta); mono-methyl-l-arginine, which blocks nitric oxide productio...
