Primers used for MLST of Staphylococcus lugdunensis
Genes
The Staphylococcus lugdunensis MLST scheme uses internal fragments of the following housekeeping genes:
aroE (shikimate dehydrogenase)
dat (D-amino acid aminotransferase)
ddl (D-alanine:D-alanine ligase)
gmk (guanylate kinase)
ldh (L-lactate dehydrogenase)
recA (recombinase)
yqiL (acetyl-CoA acetyltransferase)

PCR conditions
The PCR mixtures were heated for 3 min at 95°C, then a touch-down procedure followed, consisting of 30 s at 95°C, annealing for 30 s at temperatures decreasing from 60°C to 50°C during the first 11 cycles (with 1°C decremental steps in cycles 1 to 11), and ending with an extension step at 72°C for 30 s. A total of 40 cycles were performed.
