transfer of the f ' factor to h. influenzae was verified by expression of unselected markers in h. influenzae ( lac+ or cotransfer of the nonselected antibiotic resistance ) , physical presence of a high-molecular-weight plasmid in recipient h. influenzae cells , and detection by southern hybridization analysis of dna sequences specific for the f ' factor replication and partition functions in recipient h. influenzae cells .
