Molecular diagnosis of bacteria isolated from Trifolium repens root nodules

The Fabaceae genus Trifolium comprises around 250 species widely distributed worldwide, with the temperate Northern Hemisphere exhibiting the highest variety. The plants in this genus are widely used as livestock fodder crops and are particularly significant economically.This study's objective included isolating bacteria from the root nodules of the Trifolium repens plant and diagnosing it at the molecular and microbiological levels. T. repens root nodules were used as the source of an endophytic bacteria isolated on Yeast Extract Mannitol (YEM) media that had solidified and diagnosed at the molecular level by DNA Sequencing technique for analysis of the sequence of the nitrogenous bases of 16S rRNA gene with the global database. The isolated bacteria were characteristic of greyish-white color after 48 hours of growth and appeared as a circular shape, slightly convex and gram-negative. The bacteria were resistant to the antibiotics 20µg/ml Aztreonam.The DNA sequencing technique for analysis of the sequence of the nitrogenous bases of 16S rRNA gene with the global database of the National Center for Biotechnology Information (NCBI) showed that the isolated bacteria was at least 96.22% similar to the species Acinetobacter baumannii As a result, it was recorded for the first time as Acinetobacter sp. AZS1 strain in NCBI.
