Identification of K. pneumoniae was avaluated using conventional microbiological characteristics and molecular assays. Milk specimens were collected from cattle suffered from clinical symptoms of mastitis from different farms of AL-Qadisyiah province. Out of 45 samples obtained, 20 isolates (44.4 %) were detected as K. pneumonia according to morphology of colonies and biochemical features. Molecular detection of Klebsiella pneumoniae based 16S rRNA gene for determination two virulence factor

The primers were made in this study by using NCBI-GenBank and primer3 plus design online. The primer is made by company in Korea (Bioneer). Moleculer detection of isolates which give away specific PCR products of of 312bp for magA gene and 835bp for rmpA gene. The magA and rmpA genes were amplified in six (30%)and five(25%) isolates out of 20 isolates of Klebsiella pneumonia. ‫تفاعل‬ ‫سلسلة‬ ‫تقنية‬ ‫باستخدام‬ ‫االبقار‬ ‫من‬ ‫المعزولة‬ ‫الرئوية‬ ‫الكلبسيال‬ ‫ضراوة‬ ‫عوامل‬ ‫عن‬ ‫الكشف‬ ‫البلمرة‬ ‫صادق‬ ‫ناظم‬ ‫جنان‬ ‫اسماعيل‬ ‫راضي‬ ‫جميلة‬ ‫البيطري‬ ‫الطب‬ ‫كلية‬ \ ‫القادسية‬ ‫جامعة‬ ‫الخالصة‬ ‫ا‬ ‫الخصائص‬ ‫الرئوية‬ ‫الكلبسيال‬ ‫تشخيص‬ ‫تم‬. ‫الجزيئي‬ ‫القياس‬ ‫وطرق‬ ‫التقليدية‬ ‫لميكروبيولوجية‬. ‫القادسية‬ ‫محافظة‬ ‫في‬ ‫مختلفة‬ ‫حقول‬ ‫من‬ ‫الضرع‬ ‫اللتهاب‬ ‫سريرية‬ ‫عالمات‬ ‫من‬ ‫تعاني‬ ‫ابقار‬ ‫من‬ ‫الحليب‬ ‫عينات‬ ‫جمع‬ ‫تم‬ ‫بين‬ ‫من‬ 54 ‫عن‬ ‫الكشف‬ ‫.تم‬ ‫عليها‬ ‫الحصول‬ ‫تم‬ ‫عينة‬ 02 (‫بنسبة‬ ‫عزلة‬ 5545 ‫على‬ ‫الرئوية‬ ‫الكلبسيال‬ ‫تحديد‬ ‫%).وتم‬ ‫شكل‬ ‫اساس‬. ‫الكيموحيوية‬ ‫واالختبارات‬ ‫المستعمرات‬ ‫الرئوية‬ ‫للكلبسيال‬ ‫الجزيئي‬ ‫التشخيص‬ ‫تم‬ 16srRNA ‫جين‬ ‫على‬ ‫باالستناد‬ ‫بادئات‬ ‫باستخدام‬ ‫متخصصة‬ (MagA,rmpA) ‫وهما‬ ‫الضراوة‬ ‫عوامل‬ ‫من‬ ‫عاملين‬ ‫لتحديد‬ ‫باستخدام‬ ‫الدراسة‬ ‫في‬ ‫البادئات‬ ‫هذه‬ ‫صممت‬ ‫بواسطة‬ ‫جهزت‬ ‫بادئات‬ ‫ثالث‬ ‫وصممت‬ ‫الجينات‬ ‫بنك‬ ‫نواتج‬ ‫وحددت‬ ‫للعزالت‬ ‫الجزيئي‬ ‫الكشف‬ ‫.تم‬ ‫كوريا‬ (Bioneer company) ‫شركة‬ 210 ‫و‬ 524. ‫التوالي‬ ‫على‬ ‫)للجينين‬)bp PCR
