Abstract
جهت آگاهي از گروههاي فيلوژني باكتري اشريشياكلي جدا شده از طيور گوشتي تبريز تعداد 70 باكتري اشريشياكلي جدا شده از جوجههاي گوشتي مبتلا به كلي باسيلوز مورد بررسي قرار گرفت. از اين 70 نمونه 35 نمونه (50 درصد) متعلق به گروه A ، 32 نمونه متعلق به گروه D، 2 نمونه گروه B1 و 1 نمونه متعلق به گروه B2 بودند. نتايج اين مطالعه نشان از فراواني گروه فيلوژني A دارد. اين امر حاكي از اين امر است كه عامل مسبب كلي باسيلوز در اين منطقه گروه كمسنال A مي باشد. دليل اين امر ميتواند احتمالا ناشي از انتقال ژن بين سويههاي كمنسال و غير كمنسال باشد. البته چنين ادعايي نيازمند مطالعات بيشتر است.
Abstract
In this study, to know about the phylogeny of Escherichia coli isolated from broilers with collibacillosis in
Tabriz, 70 E. coli isolates recovered from broilers with collibacillosis were characterized for phylogenetic
group (A, B1, B2, D) by multiplex PCR. Of the all 70 samples, 35 (50%) isolates were classified as type A,
32 (45%) as type D, 2 (2.8%) as type B1 and 1 (2.8%) as type B2. This study demonstrates the high
prevalence of E. coli types A and D in infected broilers. This shows that the collibacilosis-causing E. coli
bacteria are typical commensals, type A alongside pathogenic type, D in Iran. It is possible that this type of
E. coli could acquire virulence genes from pathogenic types. Of course, such a claim needs further study.
