Abstract AR
في هذه الدراسة تم فحص 1304 طائر ظاهريا سليمة و قد صنفت إلى 19 نوع مختلف من الطيور البرية المهاجرة عبر جمهورية مصر العربية، و قد تم تجميع الطيور من بور سعيد و دمياط و الفيوم و العريش شرم الشيخ.
و بالفحص الفيرولوجي وجد أن 203 (15.57 %) كانت إيجابية لفيروس الإنفلونزا.
و معظم الإصابات وجدت في الأنواع المختلفة للبط.
كما أكدت النتائج وجود حالتين فقط من نوع بط الشرشير إيجابيتين لفيروس الإنفلونزاH5N1 أحدهما ضعيف الضراوة LPAI و الثاني شديد الضراوة HPAI و تم تسجيلهم في بنك الجينات الأمريكي برقمي EF42624 and EF042623 على الترتيب.
و قد أثبت التحليل الجيني لعترة إنفلونزا الطيور شديدة الضراوة المعزولة من بط الشرشير المهاجر تتقارب بنسبة 98 % مع العترات المعزولة من الإنسان و الحيوان و المسؤولة عن إنتشار الوباء في مصر منذ فبراير 2006.
Abstract EN
During migratory seasons (2005-2006), a total of 1304 living migratory birds belonging to19 different species were collected from Port Said, Domietta, Fayoum, Arish and Sharm-Elsheikh.
All examined birds were apparently healthy.
A total of 203 (15.57 %) from examined birds were positive for influenza A virus matrix gene when tested by real-time PCR.
Duck species were the most common affected species.
Positive samples for Flu-A matrix were tested for hemagglutinine (H) and if positive for H5, further testing for the neuraminidase (N1) by real time RT-PCR.
Only two cases of Common teal species were PCR positive and the sequence from both bird samples were performed and posted on the Gen Bank as follow : Low pathogenic avian influenza "LPAI", (A / teal / Egypt / 9885-NAMRU 3 / 2005 (H5) Gen Bank accession no.
EF04262 and the highly pathogenic avian influenza ,("HPAI "H5N1) (3 / 2005 A / teal / Egypt / 14051-NAMRU (H5N1), Gen Bank accession no.
EF042624.
Phylogenetic Analysis from highly pathogenic avian influenza strains in Egypt, from humans and animals, cluster together with a bootstrap support value of 98 % (Figure, 2).
The HPAI specimen EF042624 from Common teal along the northern coast of Egypt appears to have harbored a strain very closely related to the parent strain responsible for the HPAI H5N1 outbreak in Egypt in February 2006.
