The condition of an electroporation method was re-evaluated for the introduction of foreign plasmid DNA into Rhodococcus equi. The method is based on an electroporation of the bacteria made competent by culturing in a broth containing glycine and by heat shock at 50°C. Transformation of R. equi could be achieved with a chloramphenicol-resistant shuttle vector originating from Rhodococcus fascians at an efficiency of about 104 transformants/ μg DNA. The bacteria were also shown to become competent when they were incubated with a chemical transformation buffer prior to washing with an electroporation buffer.
