title: [Mycobacterium shinshuense isolated from cutaneous ulcer lesion of right lower extremity in a 37-year-old woman].
abstract: OBJECTIVE
  Second clinical infection case of Mycobacterium shinshuense was presented, we tried the identification of M. shinshuense that is isolated from skin.
  
  
  OBJECTIVE
  Mycobacteria species isolated from cutaneous ulcer lesion of right lower extremity in a 37-year-old woman.
  
  
  METHODS
  Identification by DNA-DNA Hybridization, 16S rRNA and rpoB method as genomic level and conventional method.
  
  
  RESULTS
  It did not grow on 1% Ogawa's slant medium at both 37 degrees C and 42 degrees C, but grew at 28 degrees C. It formed yellowish colonies in the dark. It was difficult to distinguish M. shinshuense from M. ulcerans and M. marinum by DNA-DNA hybridization (DDH) and DNA sequencing. To identify that it is M. shinshuense, growth rate, temperature range of mycobacterial growth, light coloration reaction, biochemical and biological tests, and drug susceptibility testing were further explored. Finally it was identified as M. shinshuense based on these CONSIDERATION: For Mycobacteria species which grow 2 weeks after inoculation at 28 degrees C, and which is identified as M. marinum by DDH method, it is necessary to identify with sequence and conventional method.
