Identification and isolation of low pathogenic avian influenza (LPAI) virus from chicken farms in Iraq

Abstract

The objective of the study was Investigation and isolation of the Low Pathogenic Avian Influenza virus in poultry farms (Broilers and layers) in different provinces in Iraq over the period from August 2020 to June 2021. A total of 241 samples, including (Larynx, trachea & lunge) were collected from 31 poultry farms suspected to be infected with avian influenza and distributed in different provinces including Baghdad, Babylon, Wasit, Karbala & Salahuddin provinces. Collected samples were prepared firstly then viral RNA was extracted by a special viral RNA extraction kit and amplified by using primers for M gene-specific for type A influenza virus and primers specific for H9 gene of LPAI in Real-time RT-PCR which showed that from (31) farms suspected to have low pathogenic avian influenza, six farms (19.35%) were positive H9 LPAI.
