a
H. influenzae Rd (ATCC 51097) (the recipient) was transformed with PCR-amplified ftsI gene DNA fragments from group I, II, and III strains as the donors. Transformants were selected on plates containing 5 or 10 μg of CEC per ml. As an example of the transformant nomenclature, Rd3A/ME870 corresponds to Rd strain containing the ftsI gene from strain ME870.
