Field inversion gel electrophoresis (FIGE) and contour‐clamped homogenous field (CHEF) electrophoresis were used to analyse the chromosome of Yersinia ruckeri . The 8 base‐pair recognition endonucleases, Not I and Sfi I, generated less than 47 DNA fragments whose size and distribution were appropriate for pulsed field separation. Each isolate displayed a characteristic restriction pattern, with about 20% of bands in common. Depending on the strain used, the estimated genome size for this bacterial fish pathogen ranged from 4460 to 4770 kilobase pairs.
