Extrachromosomal DNA analysis and restriction endonuclease analysis of whole cellular DNA were used to characterize 30 Staphylococcus lugdunensis strains isolated from 13 different hospitals from 1977 to 1988. All the strains were susceptible to most of the antibiotics tested, including penicillin G. A single 3.2 kilobase plasmid was detected in 13 strains and one or two plasmids, ranging from 2.3 to 6.6 kilobases, were found in 7 strains. EcoRI, PstI and PvuII restriction patterns of total cellular DNA were identical for 23 isolates, indicating strong conservation of endonuclease sites in this species. One or two additional DNA bands occurred in seven isolates. Molecular markers show rather little variations between different S. lugdunensis isolates suggesting that they are closely related.
