In: Beni-Suef Veterinary Medical Journal. Beni-Suef Vetrinary Medicen Journal November 2010, 6th Scientific conference 2010.v.17(1)(Special issue)Summary: Twenty five isolates of IBV were isolated from 36 broiler aird layer cbicken farms collected from 13 governorates during.2 years started from January 2003. All the examined farms were vaccinated using the commercial live IB-H1B vaccine in addition to the IB-inactivated vaccine in the layer farm. The viruses were isolated and identified previoDsly by chicken embryo, CEK cell culture inoculation. Isolates SUbjected to RT-PeR. Four isolates; three broiler farms and one from layer farm were genotyped using 81 partial gene sequencing. Typing of the four isolates using Sl partial gene sequencing, revealed that the isolated IBV strains showed homology to Asia, Europe, USA and Middle East strains.
