To accomplish this work, a strain of H5N1 circulating in Egypt was confirmed using rapid diagnostic methods and also, reverse transcriptase polymerase chain reaction (RT-PCR) to hemagglutinin and neuraminidase genes. The virus was propagated in MDCK cell line and the viral genes were extracted and reverse transcribed individually. Individual genes were cloned in gene expression vector (PHW2000) and were used as DNA vaccine. The level of maternal antibodies was determined by ELISA to appoint the right time to give the vaccine. The chicks were divided into eight groups and each group was vaccinated by the couple of DNA NP with one of the other genes. The efficiency of coupled DNA vaccine was determined by neutralization assay and compared with the inactivated vaccine. The results showed that the vaccine that had NP with NS had adequate protection for poultry.  ردمد : 1684-5315  اسم الدورية : African Journal of Biotechnology  المجلد : 10  العدد : 26  سنة النشر : 1432 هـ 2011 م  نوع المقالة : مقالة علمية  تاريخ الاضافة على الموقع : Wednesday, June 6, 2012  الباحثون اسم الباحث (عربي) اسم الباحث (انجليزي) نوع الباحث المرتبة العلمية البريد الالكتروني ثامر أحمد فرج بوبك Bouback, Thamer Ahmd F. باحث دكتوراه th_ah@hotmail.com نزار عبدالمعطي رضوان Redwan, Nezar Abdul-Moaty باحث دكتوراه nezar_redhwan@yahoo.com الملفات اسم الملف النوع الوصف  33519.pdf pdf Abstract الرجوع إلى صفحة الأبحاث
