[Herpes simplex causing a therapy-resistant panaritium (author's transl)].

In an eight-month-old child an inflammation developed in the region of the nail bed of the right middle finger. It showed no improvement after immobilisation, extraction of the nail and antibiotics. After ten months unsuccessful treatment electron microscopy of the inflammatory tissue showed numerous Herpes simplex viruses. These increased rapidly in tissue culture and could be neutralised with antibodies against Herpes simplex virus.
