I understand that its known bacterium since you've mentioned the full name (to species level). So I suggest to read the original paper describe this bacterium, then look for the identification keys and apply these to yours (test it). If this is a new isolate then I would strongly suggest to use genetic techniques (genotype) to confirm its identity other wise it would be difficult to publish it in good journal.
Thank you Adam B Shapiro, Laith Al-ANi and Abdulhadi Albaser. Dear Abdulhadi Albaser I mentioned it to species level because last potato growing season of Bnagladesh I got scab disease in my research plot. Yes I will do follow genetic techniques too to be confirmed.
