influenza a viruses possesses two virion surface glycoproteins including haemagglutinin (ha) and neuraminidase (na). the na plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. to find out any genomic changes that might be occurred on na gene of avian influenza circulating viruses, we have genetically analy...

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 ...

This study was conducted to molecularly detect avian adenoviruses in broiler flocks showing liver lesions and respiratory syndrome in northeast Iran. In total, 60 tissue samples were collected from broiler farms with liver lesions, respiratory syndrome and also from clinically healthy flocks. Six samples were positive; however, three samples were selected for molecular studies. PCR products wer...

Avian Pasteurella multocida is the causative agent of fowl cholera, a disease much affecting the poultry industry. In order to study the efficacy of the recombinant subunit vaccine constructed with ptfA gene of avian P. multocida, the ptfA gene fragment amplified by PCR from avian P. multocida was cloned into the prokaryotic expression vector pET32a and the recombinant plasmid pET32a-ptfA was o...

Influenza is a contagious viral disease that is seen in avian, human and other mammals, so its control is important. Vaccination against influenza virus subtype H9N2 is one of the ways in controlling program, for this reason several vaccines has been produced. Recently, application of inactivated oil-emulsion vaccines in poultry for controlling low pathogenic avian influenza is increasing. At p...

Background and Aims: Avian Influenza (AI) H9N2 subtype was first reported to infect turkeys in the United States in 1966 and has been panzootic in Europe and Asia. The impact of avian influenza caused by H9N2 viruses in Iran is now significantly more severe than in previous years. Methods: Sequence analysis and phylogenetic study of the complete coding region Polymerase A (PA) gene of H9N2 subt...

background and aims: avian metapneumovirus (ampv) is rna virus responsible for upper respiratory disease in poultry which is usually accompanied by secondary bacterial infections. in iran, some molecular and serological studies indicated that ampv infection occurred in commercial poultry industry. materials and methods: in this study ampv was molecularly identified and characterized in an affec...

avian influenza (ai) is a viral respiratory disease of domestic and wild birds. in the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. cloacal swabs collected from chickens experimentally infected with h9 subtype ai virus, used in a reverse transcription-polymerase chain reaction (rt-pcr) assay for detection of ai. in infected animals, ai...
