  3. Clinical Relevant Strains

  4. Genotyping Methods • Pulsed-Field Gel Electrophoresis (PFGE) • Multilocus Sequence Typing (MLST) • Sequence protein A repeats (spa Typing)

  5. MLST - Housekeeping Genes • Carbamate kinase (arcC) • Shikimate dehyrogenase (aroE) • Glycerol kinase (glpF) • Gunylate kinase (gmk) • Triosephosphate isomerase (tpi) • Phosphate acetyltransferase (pta) • Acetyl coenzyme A acetyltransferase (yqiL) Note: genes not scattered around the genome

  6. MLST analysis of COL • Carbamate kinase Allele 3 • Shikimate dehyrogenase Allele 3 • Glycerol kinase Allele 1 • Guanylate kinase Allele 1 • Phosphate acetyltransferase Allele 4 • Triosephosphate isomerase Allele 4 • Acetyl coenzyme A acetyltransferase Allele 16 MLST = 3 3 1 1 4 4 16 = ST250

  7. MLST analysis of USA300 • Carbamate kinase Allele 3 • Shikimate dehyrogenase Allele 3 • Glycerol kinase Allele 1 • Guanylate kinase Allele 1 • Phosphate acetyltransferase Allele 4 • Triosephosphate isomerase Allele 4 • Acetyl coenzyme A acetyltransferase Allele 3 MLST = 3 3 1 1 4 4 3 = ST8

  8. MLST – Single Locus Variant (SLV) Strain: COL ST250 = 3 3 1 1 4 4 16 Strain: USA300 ST8 = 3 3 1 1 4 4 3 BOTH MEMBERS OF CLONAL COMPLEX 8

  14. ST45; USA600 ST36: USA200 ST22 – USA900 ST239: USA1100 ST72: USA700 ST59: USA1000 ST8: USA300, USA500 ST1: USA400 ST15: USA1100 ST5: USA100, USA800 MRSA - USA TYPES

  15. spa Typing • Protein A gene (spa) • Present in all S. aureus strains • Sequence analysis of the variable number tandem repeats in the 3’ region of the S. aureus protein A gene

  16. Protein A Gene Organization

  17. spa Typing • Sequence PCR amplicons of the repeat region • Amplicons range in size: ~200-600 bp • Web-based programs to analyze repeats • Ridom (Germany) - eGenomics (US) • Identify and name each repeat cassette • The repeat profile equals the spa type

  18. MLST and spa Typing • Consensus between two typing methods • Database give comparable groups • spa typing - faster molecular clock

  19. Fowler et al - 2007, JID;196:738

  20. NARSA COLLECTION • Typed 208 / 242 isolates • 72 MRSA • MLST and spa typing • 49 Sequence Types (STs) • 79 spa Types • 101 different genotypes (ST and spa Types)

  30. IN SUMMARY • NARSA Collection is representative of the species, but not comprehensive • MLST and spa provide an objective approach to distinguish the NARSA collection • How should the data be presented

  31. GOING FORWARD • Should all strains be catalogued with both MLST and spa? • Should we extend the genotype/phenotype? • Focus only on research strains? • How to update the NARSA strain information
