Anergy means the intradermal tuberculin test is negative. The lack of cellular defence against M. tuberculosis can be caused by several circumstances. A lack of contact with M. tuberculosis as well as a weakened immune defence can be decisive for the negative tuberculin test.

 

Examples:

  • Tuberculous primary complex.
  • Tuberculosis cutis miliaris disseminata.
  • Tuberculosis (miliaris) ulcerosa mucosae et cutis.
  • Tuberculosis fungosa serpiginosa.
