Short communication SEROSURVEY OF H9N2 AVIAN INFLUENZA VIRUS DURING RESPIRATORY DISEASE OUTBREAKS IN BROILER FLOCKS IN DEZFUL, SOUTHERN IRAN
نویسنده
چکیده
Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent was a low-pathogenicity H9N2 avian influenza virus that caused frequent episodes of high mortality in broiler chicken farms in Iran and some other Asian countries. This study was designed to investigate the prevalence of AIV H9N2 subtype in commercial chicken flocks in Dezful, southern Iran. Serum samples from 160 broilers (8 broiler flocks) with respiratory symptoms, were examined by hemagglutination inhibition (HI) test for specific antibodies against AIV H9N2 subtype. Overall HI titre and seroprevalence against H9N2 were 7.3 and 75.95%, respectively.

Isolation of H9N2 Subtype of Avian Influenza Viruses during an Outbreak in Chickens in Iran
Avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. The presence of avian influenza viruses (AIV) in chickens in Iran has not been previously reported. An avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in July 1998. Three AIV isolates designated as 101, 102 and 10...

Widespread occurrence of H9N2 low pathogenic avian influenza (LPAI) viruses in many Asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of H9N2 virus infection. In this study, tissue tropism and dissemination of A/Chicken/Iran/772/1998(H9N2) virus throughout the body of broiler chickens were investigated. The clinical signs, gross lesions and antibo...

Avian influenza virus (AIV) H9N2 is endemic in Iran and its large-scale circulation in the poultry industry of the country is devastating. This virus was first reported in the industrial poultry populations of Iran in July 1998. Some of the published studies showed that inactivated avian influenza (AI) vaccines are capable of inducing an immune response and providing protection against morbidit...
متن کاملAssessment of a rapid immunochromatographic assay for the detection of avian influenza viruses
Rapid spreading of the low pathogenic avian influenza virus (AIV) caused by the H9N2 subtype and the highly pathogenic AIV caused by H5N1 have caused serious economic losses in the poultry industries of Asia. Therefore, the early detection of AIVs is crucial for the control of the disease. In the present study, the applicability of a rapid immunochromatographic (RIC) assay, which specifically d...
متن کاملA Survey of Pathogenic Avian Mycoplasma Involvement in Multicausal Respiratory Disease in Broiler Flocks
BACKGROUND: Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most important and pathogenic mycoplasma in chicken production. The tendency of avian mycoplasma for interaction with other pathogen is well-known. Interaction within several disease-producing factors in respiratory tract exacerbate the disease and known as multicausal respiratory disease. OBJECTIVES: In recent years...
