Figure Lengend Snippet: (A) Comparison of representative S. capitis chromosome sequences relative to S. capitis NZ-SC16875, illustrating a high level of conservation among the international NICU-associated S. capitis BP3 isolates (inner six rings). Variable regions are annotated in the outer ring. These regions include two putative bacteriophages (phage 1 and phage 2), the SCC cad -SCC ars -SCC cop region, and the embp gene (B) Schematic diagram illustrating the genetic organization of the composite SCC cad -SCC ars -SCC cop element in BP3 lineage S. capitis isolates NZ-SC16875 and CR01. Also included are the SCC mec V elements of S. schleiferi TSCC54, S. pseudintermedius 06-3228, S. aureus JCSC6944, and MRSA P126, and S. haemolyticus NW19A, as well as the SCC cad -SCC ars -SCC cop regions of S. haemolyticus S167 and SH621 and S. simulans FDAARGOS_124 for comparison. Green and yellow arrows indicate sequences present within SCC mec V regions; orange arrows are CRISPR-associated genes; and blue, purple, and red arrows indicate genes within SCC cad -SCC ars -SCC cop regions. The direction of the arrows indicates the direction of transcription for open reading frames. Only coding sequences of >200 bp are shown. Shaded areas represent regions that share >99% nucleotide sequence identity (pink denotes the same orientation, and blue denotes the reverse orientation). Note that the S. capitis NZ-SC16875 region is shown at the top and bottom of the figure for ease of comparison.
Article Snippet: Initial identification of S. capitis isolates was performed using matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry (Bruker Daltonics, USA), and urease and maltose fermentation tests were used to differentiate between S. capitis subsp. urealyticus and S. capitis subsp. capitis .
