Partial DNA sequences were determined, and several homologies were discovered with known S. aureus sequences (plasmid pSH6 DNA with insertion sequences, agrA and agrB sequences, hld genes, the gene for 23S rRNA, the lysyl tRNA synthetase gene, and the threonyl tRNA synthetase gene) and with genes from other species (Haemophilus influenzae bexA and Bacillus subtilis spoF and ctrA).
