An isolated polynucleotide segment comprising:
- a first polynucleotide sequence, or the full complement of the entire length of the first polynucleotide sequence, wherein the first polynucleotide sequence is selected from the group consisting of:
- (a) a polynucleotide comprising a polynucleotide as set forth in SEQ ID NO:1;
- and,
- (b) a nucleic acid sequence identical to the polynucleotide of (a) except that, over the entire length corresponding to the polynucleotide of (a), up to thirty nucleotides are substituted, deleted or inserted for every 100 nucleotides of the polynucleotide of (a)
- and wherein the first polvnucleotide sequence detects Staphylococcus aureus.
An isolated polynucleotide segment, comprising a first polynucleotide sequence or the full complement of the entire length of the first polynucleotide sequence, wherein the first polynucleotide sequence hybridizes to the full complement of SEQ ID NO:1, wherein the hybridization conditions include incubation at 42° C. in a solution comprising:
- 50% formamide, 5×SSC (150 mM NaCl, 15 mM trisodium citrate), 50 mM sodium phosphate (pH7.6), 5×Denhardt's solution, 10% dextran sulfate, and 20 micrograms/ml denatured, sheared salmon sperm DNA, followed by washing in 0.1×SSC at 65° C.;
- and wherein the first polynucleotide sequence is identical to nucleotides 1 to 1365 of SEQ ID NO:1 except that, over the entire length corresponding to SEQ ID NO:1, up to five nucleotides are substituted, deleted or inserted for every 100 nucleotides of SEQ ID NO:1;
- and wherein the first polynucleotide sequence detects Staphylococcus aureus.
An isolated polynucleotide segment comprising a first polynucleotide sequence, or the full complement of the entire length of the first polynucleotide sequence, wherein the first polynucleotide sequence is a polynucleotide encoding a polypeptide consisting of SEQ ID NO:4.
