title: Characterization of cryptic plasmids pDP1 and pSMB1 of Streptococcus pneumoniae.
abstract: Cryptic plasmids pDP1 and pSMB1 from clinical strains of Streptococcus pneumoniae isolated 74 years apart were found to be essentially identical in their nucleotide sequence. pDP1, 3161 bp, contains five codirectional ORFs and presents all the general features of plasmids replicating by the rolling circle mechanism. The rep gene, 963 bp, is highly homologous to the rep gene of other streptococcal plasmids of the pC194 family.
