title: [Pilot study on the use of diode laser therapy for treatment of dermatitis in koi carp (Cyprinus carpio)].
abstract: OBJECTIVE
  Therapy of dermatitis in koi using a diode laser technique.
  
  
  METHODS
  A diode laser with a wavelength of 980 nm and an energy density of 9 J/cm(2) was used to treat defined skin alterations in ten koi carp. The clinical situation after repeated laser application was recorded. In addition, the diode laser was used for surgical removal of proliferative skin alterations caused by Dermocystidium sp. in two koi ponds.
  
  
  RESULTS
  An improvement of the clinical situation following laser therapy was seen in nine of the ten koi carp. Complete healing of the wound area occurred in four carp. A pronounced healing process was observed in four patients and a low healing tendency in one fish. Healing of the skin lesions following removal of the alterations caused by Dermocystidium sp. was unproblematic in one pond, whereas in the other collection a repeated treatment was necessary due to relapse of the alterations.
  
  
  CONCLUSIONS
  Diode laser therapy for treatment of dermatitis in koi is a promising technique. An expedited wound healing process was seen in wound areas that were present for long periods and resistant to previous therapy attempts, including antibiotics. Wound healing was undisturbed following surgical use of the laser technique for the removal of skin proliferations. Therefore, the diode laser technique can be recommended for the treatment of dermatitis in koi, especially in cases of unsuccessful treatment using anti-infective drugs, and for the treatment of Dermocystidium infections.
