Abstract
Sequences related to the Staphylococcus aureus accessory gene regulator (agr) were demonstrated in S. lugdunensis by Southern blot analysis of 13 strains and sequencing of the S. lugdunensis agr-like locus (agr-sl). Northern blot analysis of cellular RNA revealed the presence of a transcript having homology with the agr-P3 transcript (RNAIII) for three of the six strains tested. The three strains containing this transcript produce a hemolysin with phenotypic properties similar to that of S. aureus δ-hemolysin. Nevertheless, unlike agr-P3 from S. aureus, agr-sl does not encode any potential peptides homologous to S. aureus δ-hemolysin, suggesting that the hemolytic activity detected in S. lugdunensis is encoded elsewhere and may be controlled by agr-sl.
