Elms (Ulmusspp.) are popular species of deciduous trees belonging to the family Ulmaceae. Elms are ornamental trees commonly used in cities and forests. During late June 2015, isolation of bacterial associated was performed for the first time on elm trees, in the Tabriz (East Azarbaijan Province, Iran). Based on morphological, biochemical and molecular characteristics, the isolates were identified as Arthrobacter agilis. This study provides the first report on the occurrence of this bacterium on elm trees in Iran.
